cd49b84d61 mfd: stmfx: Uninitialized variable in stmfx_irq_handler()
The problem is that on 64bit systems then we don't clear the higher
bits of the "pending" variable.  So when we do:

        ack = pending & ~BIT(STMFX_REG_IRQ_SRC_EN_GPIO);
        if (ack) {

the if (ack) condition relies on uninitialized data.  The fix it that
I've changed "pending" from an unsigned long to a u32.  I changed "n" as
well, because that's a number in the 0-10 range and it fits easily
inside an int.  We do need to add a cast to "pending" when we use it in
the for_each_set_bit() loop, but that doesn't cause a problem, it's
fine.

62e59c4e69 clk: Remove io.h from clk-provider.h
Now that we've gotten rid of clk_readl() we can remove io.h from the
clk-provider header and push out the io.h include to any code that isn't
already including the io.h header but using things like readl/writel,
etc.

I also reordered a couple includes when they weren't alphabetical and
removed clk.h from kona, replacing it with clk-provider.h because
that driver doesn't use clk consumer APIs.

4f799e47ad mfd: axp20x: Allow the AXP223 to be probed by I2C
The AXP223 can be used both using the RSB proprietary bus, or a more
traditional I2C bus. The RSB is a faster bus and provides more features
(like some integrity checks on the messages), so it's usually preferrable
to use it, but since it's proprietary, when we want to use the PMIC in a
multi-master setup, the i2c might make sense as well.

Let's add that possibility.

48171d0ea7 mfd: twl6040: Fix device init errors for ACCCTL register
I noticed that we can get a -EREMOTEIO errors on at least omap4 duovero:

twl6040 0-004b: Failed to write 2d = 19: -121

And then any following register access will produce errors.

There 2d offset above is register ACCCTL that gets written on twl6040
powerup. With error checking added to the related regcache_sync() call,
the -EREMOTEIO error is reproducable on twl6040 powerup at least
duovero.

To fix the error, we need to wait until twl6040 is accessible after the
powerup. Based on tests on omap4 duovero, we need to wait over 8ms after
powerup before register write will complete without failures. Let's also
make sure we warn about possible errors too.

Note that we have twl6040_patch[] reg_sequence with the ACCCTL register
configuration and regcache_sync() will write the new value to ACCCTL.

4c11edfcf7 Remove MODULE_ALIAS() calls that take undefined macro
These files do not define (USBHS_)DRIVER_NAME. Yet, they can be
successfully compiled because they are never built as a module by
anyone, i.e, the MODULE_ALIAS() calls are always no-op.

A problem showed up when a patch "moduleparam: Save information about
built-in modules in separate file" was applied. With this new feature,
MODULE_*() will be populated even if the callers are built-in.

To avoid the build errors, the lines referencing to the undefined
macro must be removed.

The complete fix is to remove all MODULE_* and #include <linux/module.h>
like many "make ... explicitly non-modular" commits did.

For now, I am touching only the offending lines.

The SOCFPGA System Manager register block aggregates different

On 32 bit ARM parts, handle in the same way as syscon.
On 64 bit ARM parts, the System Manager can only be accessed by
EL3 secure mode. Since a SMC call to EL3 is required, this new
driver uses regmaps similar to syscon to handle the SMC call.

Since regmaps abstract out the underlying register access, the
changes to drivers accessing the System Manager are minimal.

Since commit 6e2bd956936 ("i2c: omap: Use noirq system sleep pm ops to idle device for suspend")

This happens when we wakeup via something behing twl4030 (powerbutton or rtc

Disable the irq on suspend and enable it on resume to avoid
having i2c access problems when the irq registers are checked.

regulator: wm8400: Get rid of wm8400_block_read/wm8400_set_bits functions
The only user of wm8400_block_read/wm8400_set_bits functions is the
wm8400 regulator driver. At the context of all the callers, we can
use regmap_bulk_read/regmap_update_bits directly.
Thus remove wm8400_block_read/wm8400_set_bits functions.

3601fe43e8 This is the bulk of GPIO changes for the v5.1 cycle:
Core changes:
 
 - The big change this time around is the irqchip handling in
   the qualcomm pin controllers, closely coupled with the
   gpiochip. This rework, in a classic fall-between-the-chairs
   fashion has been sidestepped for too long. The Qualcomm
   IRQchips using the SPMI and SSBI transport mechanisms have
   been rewritten to use hierarchical irqchip. This creates
   the base from which I intend to gradually pull support for
   hierarchical irqchips into the gpiolib irqchip helpers to
   cut down on duplicate code. We have too many hacks in the
   kernel because people have been working around the missing
   hierarchical irqchip for years, and once it was there,
   noone understood it for a while. We are now slowly adapting
   to using it. This is why this pull requests include changes
   to MFD, SPMI, IRQchip core and some ARM Device Trees
   pertaining to the Qualcomm chip family. Since Qualcomm have
   so many chips and such large deployments it is paramount
   that this platform gets this right, and now it (hopefully)
   does.
 
 - Core support for pull-up and pull-down configuration, also
   from the device tree. When a simple GPIO chip support a
   "off or on" pull-up or pull-down resistor, we provide a
   way to set this up using machine descriptors or device tree.
   If more elaborate control of pull up/down (such as
   resistance shunt setting) is required, drivers should be
   phased over to use pin control. We do not yet provide a
   userspace ABI for this pull up-down setting but I suspect
   the makers are going to ask for it soon enough. PCA953x
   is the first user of this new API.
 
 - The GPIO mockup driver has been revamped after some
   discussion improving the IRQ simulator in the process.
   The idea is to make it possible to use the mockup for
   both testing and virtual prototyping, e.g. when you do
   not yet have a GPIO expander to play with but really
   want to get something to develop code around before
   hardware is available. It's neat. The blackbox testing
   usecase is currently making its way into kernelci.
 
 - ACPI GPIO core preserves non direction flags when updating
   flags.
 
 - A new device core helper for devm_platform_ioremap_resource()
   is funneled through the GPIO tree with Greg's ACK.
 
 New drivers:
 
 - TQ-Systems QTMX86 GPIO controllers (using port-mapped
   I/O)
 
 - Gateworks PLD GPIO driver (vaccumed up from OpenWrt)
 
 - AMD G-Series PCH (Platform Controller Hub) GPIO driver.
 
 - Fintek F81804 & F81966 subvariants.
 
 - PCA953x now supports NXP PCAL6416.
 
 Driver improvements:
 
 - IRQ support on the Nintendo Wii (Hollywood) GPIO.
 
 - get_direction() support for the MVEBU driver.
 
 - Set the right output level on SAMA5D2.
 
 - Drop the unused irq trigger setting on the Spreadtrum
   driver.
 
 - Wakeup support for PCA953x.
 
 - A slew of cleanups in the various Intel drivers.

384d11fa0e ARM: SoC driver updates for 5.1
As usual, the drivers/tee and drivers/reset subsystems get merged
 here, with the expected set of smaller updates and some new hardware
 support. The tee subsystem now supports device drivers to be attached
 to a tee, the first example here is a random number driver with its
 implementation in the secure world.
 
 Three new power domain drivers get added for specific chip families:
  - Broadcom BCM283x chips (used in Raspberry Pi)
  - Qualcomm Snapdragon phone chips
  - Xilinx ZynqMP FPGA SoCs
 
 One new driver is added to talk to the BPMP firmware on NVIDIA
 Tegra210
 
 Existing drivers are extended for new SoC variants from NXP,
 NVIDIA, Amlogic and Qualcomm.

ff4c25f26a dma-mapping: improve selection of dma_declare_coherent availability
This API is primarily used through DT entries, but two architectures
and two drivers call it directly.  So instead of selecting the config
symbol for random architectures pull it in implicitly for the actual
users.  Also rename the Kconfig option to describe the feature better.

d037739220 mfd/sm501: depend on HAS_DMA
Currently the sm501 mfd driver can be compiled without any dependencies,
but through the use of dma_declare_coherent it really depends on
having DMA and iomem support.  Normally we don't explicitly require DMA
support as we have stubs for it if on UML, but in this case the driver
selects support for dma_declare_coherent and thus also requires
memmap support.  Guard this by an explicit dependency.

1a25d59a55 mfd: pm8xxx: revert "disassociate old virq if hwirq mapping already exists"
Now that ssbi-gpio is a proper hierarchical IRQ chip, and all in-tree
users of device tree have been updated, we can now drop the hack that
was introduced to disassociate the old Linux virq if a hwirq mapping
already exists. That patch was introduced to not break git bisect for
any existing boards.

This change was tested on an APQ8060 DragonBoard.

ee08e24c2e mfd: pm8xxx: disassociate old virq if hwirq mapping already exists
Check to see if the hwirq is already associated with another virq on
this IRQ domain. If so, then disassociate it before associating the
hwirq with the new virq.

This is a temporary hack that is needed in order to not break git
bisect for existing boards. The next patch in this series converts
ssbi-gpio to be a hierarchical IRQ chip, then there are several patches
to update all of the device tree files, and finally this patch will be
reverted within the same patch series.

IRQs for ssbi-gpio are all initially setup without an IRQ hierarchy
this driver is probed due to the interrupts property in device tree.
Once ssbi-gpio is converted to be a hierarchical IRQ chip in the next
patch, existing users of gpio[d]_to_irq() will call pmic_gpio_to_irq(),
and that will use the new IRQ chip code in ssbi-gpio that sets up the
IRQ in an IRQ hierarchy. The hwirq is now associated with two Linux
virqs and interrupts will not work as expected. This patch corrects
that issue.

3324a7c1a2 mfd: pm8xxx: convert to v2 irq interfaces to support hierarchical IRQ chips
Convert the PM8XXX IRQ code to use the version 2 IRQ interface in order
to support hierarchical IRQ chips. This is necessary so that ssbi-gpio
can be setup as a hierarchical IRQ chip with PM8xxx as the parent. IRQ
chips in device tree should be usable from the start without having to
make an additional call to gpio[d]_to_irq() to get the proper IRQ on the
parent.

pm8821_irq_domain_ops and pm8821_irq_domain_map are removed by this
patch since the irq_chip is now contained in the pm_irq_data struct, and
that allows us to use a common IRQ mapping function.

While ioctls normally return a negative error or 0 on success, this is not
the case for CROS_EC_DEV_IOCXCMD in the cros_ec driver, which returns the
number of bytes read instead. However, CROS_EC_DEV_IOCRDMEM in the same
driver does not return the number of byte read on success. This is both
inconsistent and problematic, since the amount of returned data can be
dynamic. Have it return the number of data bytes for consistency.

66265e719b mfd: tps68470: Drop unused MODULE_DEVICE_TABLE
The Kconfig currently controlling compilation of this code is:

drivers/mfd/Kconfig:config MFD_TPS68470
drivers/mfd/Kconfig:    bool "TI TPS68470 Power Management / LED chips"

...meaning that it currently is not being built as a module by anyone.

Hence we remove the MODULE_DEVICE_TABLE since it is a no-op for
non-modular code.

There is no removal of <linux/module.h> here because there isn't one.
Instead, it is relying on including that implicitly from an ACPI header.

In cleaning up the ACPI instance of module.h (which also isn't strictly
needed), then this mfd driver breaks when MODULE_DEVICE_TABLE becomes
undefined here.

The easiest dependency solution is to simply defer the ACPI cleanup
until this change is present in mainline.

422dcafe47 mfd: lochnagar: Add support for the Cirrus Logic Lochnagar
Lochnagar is an evaluation and development board for Cirrus
Logic Smart CODEC and Amp devices. It allows the connection of
most Cirrus Logic devices on mini-cards, as well as allowing
connection of various application processor systems to provide a
full evaluation platform. This driver supports the board
controller chip on the Lochnagar board. Audio system topology,
clocking and power can all be controlled through the Lochnagar
controller chip, allowing the device under test to be used in
a variety of possible use cases.

As the Lochnagar is a fairly complex device this MFD driver
allows the drivers for the various features to be bound
in. Initially clocking, regulator and pinctrl will be added as
these are necessary to configure the system. But in time at least
audio and voltage/current monitoring will also be added.

9f208eca4f mfd: sm501: Use struct_size() in devm_kzalloc()
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    struct boo entry[];
};

instance = devm_kzalloc(dev, sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL);

drivers/mfd/Kconfig:config MFD_WM831X_I2C
drivers/mfd/Kconfig:    bool "Wolfson Microelectronics WM831x/2x PMICs with I2C"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.

Since module_init was not in use by this code, the init ordering
remains unchanged with this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

0545625baa mfd / platform: cros_ec_vbc: Instantiate only if the EC has a VBC NVRAM
The cros-ec-vbc driver is DT-only and there is a DT property that
indicates if the EC has the VCB NVRAM, in such case instantiate the
driver but don't instantiate on the other cases.

To do this move the check code to its parent instead of play with the
attribute group visibility. This changes a bit the actual behaviour.
Before the patch if an EC doesn't have a VBC NVRAM an empty vbc folder
is created in /sys/class/chromeos/<ec-device-name>, after the patch the
empty folder is not created, so, the folder is only created if the vbc
is set.

9baddb61df mfd: Fix unmet dependency warning for MFD_TPS68470
After commit 5d32a66541 ("PCI/ACPI: Allow ACPI to be built without
CONFIG_PCI set") dependencies on CONFIG_PCI that previously were
satisfied implicitly through dependencies on CONFIG_ACPI have to be
specified directly.

WARNING: unmet direct dependencies detected for I2C_DESIGNWARE_PLATFORM
  Depends on [n]: I2C [=y] && HAS_IOMEM [=y] && (ACPI [=y] && COMMON_CLK [=n] || !ACPI [=y])
  Selected by [y]:
  - MFD_TPS68470 [=y] && HAS_IOMEM [=y] && ACPI [=y] && I2C [=y]=y

MFD_TPS68470 is an ACPI only device and selects I2C_DESIGNWARE_PLATFORM.

I2C_DESIGNWARE_PLATFORM does not have any configuration today for ACPI
support without CONFIG_PCI set.

For sake of a quick fix this introduces a new mandatory dependency to
the driver which may survive without it. Otherwise we need to revisit
the driver architecture to address this properly.

670c672608 soc: bcm: bcm2835-pm: Add support for power domains under a new binding.
This provides a free software alternative to raspberrypi-power.c's
firmware calls to manage power domains.  It also exposes a reset line,
where previously the vc4 driver had to try to force power off the
domain in order to trigger a reset.

3f2d347e85 mfd: exynos-lpass: Enable UART module support
This patch enables proper interrupts routing between UART module
in Exynos Audio SubSystem and the rest of the SoC. This routing is
completely transparent for UART device and CPU/GIC. UART driver requests
interrupts from the respective controller and enables/masks/handles it
by itself via standard methods.

There are boards (for example TM2), which use UART module in Exynos Audio
SubStem for communication with BlueTooth chip.

In the axp20x driver, the various mfd_cell lists had varying amounts

Re-align the right hand side of the assignments with the least amount

ac4ca4b9f4 mfd: tps6586x: Handle interrupts on suspend
The tps6586x driver creates an irqchip that is used by its various child
devices for managing interrupts. The tps6586x-rtc device is one of its
children that uses the tps6586x irqchip. When using the tps6586x-rtc as
a wake-up device from suspend, the following is seen:

 PM: Syncing filesystems ... done.
 Freezing user space processes ... (elapsed 0.001 seconds) done.
 OOM killer disabled.
 Freezing remaining freezable tasks ... (elapsed 0.000 seconds) done.
 Disabling non-boot CPUs ...
 Entering suspend state LP1
 Enabling non-boot CPUs ...
 CPU1 is up
 tps6586x 3-0034: failed to read interrupt status
 tps6586x 3-0034: failed to read interrupt status

The reason why the tps6586x interrupt status cannot be read is because
the tps6586x interrupt is not masked during suspend and when the
tps6586x-rtc interrupt occurs, to wake-up the device, the interrupt is
seen before the i2c controller has been resumed in order to read the
tps6586x interrupt status.

The tps6586x-rtc driver sets it's interrupt as a wake-up source during
suspend, which gets propagated to the parent tps6586x interrupt.
However, the tps6586x-rtc driver cannot disable it's interrupt during
suspend otherwise we would never be woken up and so the tps6586x must
disable it's interrupt instead.

Prevent the tps6586x interrupt handler from executing on exiting suspend
before the i2c controller has been resumed by disabling the tps6586x
interrupt on entering suspend and re-enabling it on resuming from
suspend.

This function is supposed to return zero on success or negative error
codes on error.  Unfortunately, there is a bug so it sometimes returns
non-zero, positive numbers on success.

I noticed this bug during review and I can't test it.  It does appear
that the return is sometimes propogated back to _regmap_read() where all
non-zero returns are treated as failure so this may affect run time.

48a2ca0ee3 Revert "mfd: cros_ec: Use devm_kzalloc for private data"
This reverts commit 3aa2177e47.

That commit triggered a new WARN when unloading the module (see at the
end of the commit message). When a class_dev is embedded in a structure
then that class_dev is the thing that controls the lifetime of that
structure, for that reason device managed allocations can't be used here.
See Documentation/kobject.txt.

Revert the above patch, so the struct is allocated using kzalloc and we
have a release function for it that frees the allocated memory, otherwise
it is broken.

 ------------[ cut here ]------------
 Device 'cros_ec' does not have a release() function, it is broken and must be fixed.

regulator: wm8994: Pass descriptor instead of GPIO number
Instead of passing a global GPIO number for the enable GPIO, pass
a descriptor looked up from the device tree node or the board file
decriptor table for the regulator.

There is a single board file passing the GPIOs for LDO1 and LDO2
through platform data, so augment this to pass descriptors
associated with the i2c device as well.

The special GPIO enable DT property for the enable GPIO is
nonstandard but this was accomodated in
commit 6a537d4846
"gpio: of: Support regulator nonstandard GPIO properties".

55143439b7 mfd: mc13xxx-core: Fix PMIC shutdown when reading ADC values
When trying to read any MC13892 ADC channel on a imx51-babbage board:

The MC13892 PMIC shutdowns completely.

After debugging this issue and comparing the MC13892 and MC13783
initializations done in the vendor kernel, it was noticed that the
CHRGRAWDIV bit of the ADC0 register was not being set.

This bit is set by default after power on, but the driver was
clearing it.

After setting this bit it is possible to read the ADC values correctly.

The main MFD driver for Samsung PMICs (S2MPSXX, S5M876X) used with
Exynos SoCs can be compiled and used as a module.  The dependent clock,
regulator and RTC drivers already can be built as a module.

Building entire set of drivers as modules might require using initial
ramdisk and can make booting process longer (due to probe deferrals).
However adding such option is useful for testing and for multi-platform
configurations.

This also add required module authors to sec-irq.c file based on recent

The biggest chunk of the regulator changes for this release outside of

 descriptor API, there's a small addition to the GPIO API plus a bunch of
 updates to board files to implement it.  This is some really welcome
 work from Linus Walleij that's had a bunch of review and has been
 sitting in -next for a while so I'm fairly happy there's no major
 issues.
 
  - Helpers for overlapping linear ranges.
  - Display opmode and consumer requested load in the regualtor_summary
    file in debugfs, plus a fix there.
  - Support for the fun and entertaining power off mechanism that the
    pfuze100 hardware implements.
  - Conversion of the fixed regulator API to use GPIO descriptors,
    including pulling in a bunch of patches to a bunch of board files.
  - New drivers for Cirrus Logic Lochnagar, Qualcomm PMS405, Rohm
    BD71847, ST PMIC1, and TI LM363x devices.

10492ee8ed mfd: omap-usb-host: Fix dts probe of children
It currently only works if the parent bus uses "simple-bus". We
currently try to probe children with non-existing compatible values.
And we're missing .probe.

I noticed this while testing devices configured to probe using ti-sysc
interconnect target module driver. For that we also may want to rebind
the driver, so let's remove __init and __exit.

9612f8f503 mfd: menelaus: Fix possible race condition and leak
The IRQ work is added before the struct rtc is allocated and registered,
but this struct is used in the IRQ handler. This may lead to a NULL pointer
dereference.

Switch to devm_rtc_allocate_device/rtc_register_device to allocate the rtc
before calling menelaus_add_irq_work.

Also, this solves a possible leak as the RTC is never released.

regmap: split up regmap_config.use_single_rw
Split regmap_config.use_single_rw into use_single_read and
use_single_write. This change enables drivers of devices which only
support bulk operations in one direction to use the regmap_bulk_*()
functions for both directions and have their bulk operation split into
single operations only when necessary.

Update all struct regmap_config instances where use_single_rw==true to
instead set both use_single_read and use_single_write. No attempt was
made to evaluate whether it is possible to set only one of
use_single_read or use_single_write.

99cc7ad46b Merge branch 'i2c/for-4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:

 - the core has now a lockless variant of i2c_smbus_xfer. Some open
   coded versions of this got removed in drivers. This also enables
   proper SCCB support in regmap.

 - locking got a more precise naming. i2c_{un}lock_adapter() had to go,
   and we know use i2c_lock_bus() consistently with flags like
   I2C_LOCK_ROOT_ADAPTER and I2C_LOCK_SEGMENT to avoid ambiguity.

 - the gpio fault injector got a new delicate testcase

 - the bus recovery procedure got fixed to handle the new testcase
   correctly

 - a new quirk flag for controllers not able to handle zero length
   messages together with driver updates to use it

 - new drivers: FSI bus attached I2C masters, GENI I2C controller, Owl
   family S900

 - and a good set of driver improvements and bugfixes

The AXP806 can operate in a standalone "self-working" mode, in which it
is also responsible for power control of the overall system. This mode
is similar to the master mode, but the EN/PWRON pin functions as a power

This patch adds code checking for the new "x-powers,self-working-mode"
property, and a separate mfd_cell list that includes the power button

Relying on serial port defaults for flow control and parity can result

6afebb70ee mfd: hi655x: Fix regmap area declared size for hi655x

LTP Functional tests have caused a bad paging request when triggering
the regmap_read_debugfs() logic of the device PMIC Hi6553 (reading
regmap/f8000000.pmic/registers file during read_all test):

Unable to handle kernel paging request at virtual address ffff0

Investigations have showed that, when triggered by debugfs read()
handler, the mmio regmap logic was reading a bigger (16k) register area
than the one mapped by devm_ioremap_resource() during hi655x-pmic probe
time (4k).

This commit changes hi655x's max register, according to HW specs, to be
the same as the one declared in the pmic device in hi6220's dts, fixing
the issue.

50d44f82c7 mfd: dln2: Use irqsave() in USB's complete callback
The USB completion callback does not disable interrupts while acquiring
the lock. We want to remove the local_irq_disable() invocation from
__usb_hcd_giveback_urb() and therefore it is required for the callback
handler to disable the interrupts while acquiring the lock.
The callback may be invoked either in IRQ or BH context depending on the
USB host controller.
Use the _irqsave() variant of the locking primitives.

f99fea9497 mfd: arizona: Don't use regmap_read_poll_timeout
Some Arizona CODECs have a small timing window where they will
NAK an I2C transaction if it happens before the boot done bit is
set. This can cause the read of the register containing the boot
done bit to fail until it is set. Since regmap_read_poll_timeout
will abort polling if a read fails it can't be reliably used to
poll the boot done bit over I2C.

Do a partial revert of ef84f885e0 ("mfd: arizona: Refactor
arizona_poll_reg"), removing the regmap_read_poll_timeout but
leaving the refactoring to make the arizona_poll_reg take more
sensible arguments.

After this patch, there are 225 files that use <linux/mod_devicetable.h>,
for a reduction of around 3900 times that <linux/mod_devicetable.h>
does not have to be read & parsed.

as well as handling cases of:

        devm_kzalloc(handle, a * b * c, gfp)

with:

        devm_kzalloc(handle, array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        devm_kcalloc(handle, array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        devm_kzalloc(handle, 4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".

The Coccinelle script used for this was:

6396bb2215 treewide: kzalloc() -> kcalloc()
The kzalloc() function has a 2-factor argument form, kcalloc(). This
patch replaces cases of:

        kzalloc(a * b, gfp)

with:
        kcalloc(a * b, gfp)

as well as handling cases of:

        kzalloc(a * b * c, gfp)

with:

        kzalloc(array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        kzalloc_array(array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        kzalloc(4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The Coccinelle script used for this was:

68cc38ff33 regulator: Updates for v4.18
Quite a lot of core work this time around, though not 100% successful.
 
 We gained support for runtime mode changes thanks to David Collins and
 improved support for write only regulators (ones where we can't read
 back the configuration) from Douglas Anderson.
 
 There's been quite a bit of work from Linus Walleij on converting from
 specfying GPIOs by numbers to descriptors.  Sadly the testing turned out
 to be less good than we had hoped and so a lot of this had to be
 reverted.
 
 We also have the start of updates to use coupled regulators from Maciej
 Purski, unfortunately there are further problems there so the last
 couple of patches have been reverted.
 
 We also have new drivers for BD71837 and SY8106A devices, SAW regulators
 on Qualcomm SPMI and dropped support for some preproduction chips
 that never made it to market from the AB8500 driver.

ea125dedbc This is the bulk of GPIO changes for the v4.18 development
cycle.
 
 Core changes:
 
 - We have killed off VLA from the core library and all drivers.
   The background should be clear for everyone at this point:
   https://lwn.net/Articles/749064/
   Also I just don't like VLA's, kernel developers hate it when
   compilers do things behind their back. It's as simple as that.
   I'm sorry that they even slipped in to begin with.
   Kudos to Laura Abbott for exorcising them.
 
 - Support GPIO hogs in machines/board files.
 
 New drivers and chip support:
 
 - R-Car r8a77470 (RZ/G1C)
 - R-Car r8a77965 (M3-N)
 - R-Car r8a77990 (E3)
 - PCA953x driver improvements to accomodate more variants.
 
 Improvements and new features:
 
 - Support one interrupt per line on port A in the DesignWare
   dwapb driver.
 
 Misc:
 
 - Random cleanups, right header files in the drivers, some
   size optimizations etc.

Pull overflow updates from Kees Cook:
 "This adds the new overflow checking helpers and adds them to the
  2-factor argument allocators. And this adds the saturating size
  helpers and does a treewide replacement for the struct_size() usage.
  Additionally this adds the overflow testing modules to make sure
  everything works.

  I'm still working on the treewide replacements for allocators with
  "simple" multiplied arguments:

     *alloc(a * b, ...) -> *alloc_array(a, b, ...)

  and

     *zalloc(a * b, ...) -> *calloc(a, b, ...)

  as well as the more complex cases, but that's separable from this
  portion of the series. I expect to have the rest sent before -rc1
  closes; there are a lot of messy cases to clean up.

These are complex audio codec SoCs with a variety of digital and analogue

These codecs are all based off a common set of hardware IP so can be
supported by a core of common code (with a few minor device-to-device

df7c3bf24f mfd: cros_ec_dev: Don't advertise junk features on failure
If the feature query fails during this driver's probe, we memset the
features bits to 0, but then we continue to overwrite that with whatever
junk we read back when the feature probing failed. In the case of a SPI
device, it may be complete junk, causing the caller of this function to
think certain features are present when they aren't. Don't copy over the
bad message on failure so we can fail more gracefully.

4e93a65857 mfd: intel-lpss: Fix Intel Cannon Lake LPSS I2C input clock
Intel Cannon Lake PCH has much higher 216 MHz input clock to LPSS I2C
than Sunrisepoint which uses 120 MHz. Preliminary information was that
both share the same clock rate but actual silicon implements elevated
rate for better support for 3.4 MHz high-speed I2C.

This incorrect input clock rate results too high I2C bus clock in case
ACPI doesn't provide tuned I2C timing parameters since I2C host
controller driver calculates them from input clock rate.

Fix this by using the correct rate. We still share the same 230 ns SDA
hold time value than Sunrisepoint.

The cros_ec_i2c driver is still active after it had suspended or before it
resumes. Besides that, it also tried to transfer data even after the I2C
host had been suspended. This will lead the system to crash.

During the test, we also observe that the EC needs to be resumed earlier
due to some status polling from the EC FW (e.g. battery status). So we
move the PM ops to late stage to make it work normally.

11799564fc mfd: cros_ec: Retry commands when EC is known to be busy
Commit 001dde9400 ("mfd: cros ec: spi: Fix "in progress" error
signaling") pointed out some bad code, but its analysis and conclusion
was not 100% correct.

It *is* correct that we should not propagate result==EC_RES_IN_PROGRESS
for transport errors, because this has a special meaning -- that we
should follow up with EC_CMD_GET_COMMS_STATUS until the EC is no longer
busy. This is definitely the wrong thing for many commands, because
among other problems, EC_CMD_GET_COMMS_STATUS doesn't actually retrieve
any RX data from the EC, so commands that expected some data back will
instead start processing junk.

For such commands, the right answer is to either propagate the error
(and return that error to the caller) or resend the original command
(*not* EC_CMD_GET_COMMS_STATUS).

Unfortunately, commit 001dde9400 forgets a crucial point: that for
some long-running operations, the EC physically cannot respond to
commands any more. For example, with EC_CMD_FLASH_ERASE, the EC may be
re-flashing its own code regions, so it can't respond to SPI interrupts.
Instead, the EC prepares us ahead of time for being busy for a "long"
time, and fills its hardware buffer with EC_SPI_PAST_END. Thus, we
expect to see several "transport" errors (or, messages filled with
EC_SPI_PAST_END). So we should really translate that to a retryable
error (-EAGAIN) and continue sending EC_CMD_GET_COMMS_STATUS until we
get a ready status.

IOW, it is actually important to treat some of these "junk" values as
retryable errors.

Together with commit 001dde9400, this resolves bugs like the
following:

1. EC_CMD_FLASH_ERASE now works again (with commit 001dde9400, we
   would abort the first time we saw EC_SPI_PAST_END)
2. Before commit 001dde9400, transport errors (e.g.,
   EC_SPI_RX_BAD_DATA) seen in other commands (e.g.,
   EC_CMD_RTC_GET_VALUE) used to yield junk data in the RX buffer; they
   will now yield -EAGAIN return values, and tools like 'hwclock' will
   simply fail instead of retrieving and re-programming undefined time
   values

The DesignWare GPIO IP can be configured for either 1 interrupt or 1
per GPIO in port A, but the driver currently only supports 1 interrupt.
See the DesignWare DW_apb_gpio Databook description of the
'GPIO_INTR_IO' parameter.

This change allows the driver to work with up to 32 interrupts, it will
get as many interrupts as specified in the DT 'interrupts' property.
It doesn't do anything clever with the different interrupts, it just calls
the same handler used for single interrupt hardware.

STM32 Timers can support up to 7 DMA requests:
- 4 channels, update, compare and trigger.
Optionally request part, or all DMAs from stm32-timers MFD core.

Also add routine to implement burst reads using DMA from timer registers.
This is exported. So, it can be used by child drivers, PWM capture
for instance (but not limited to).

platform/chrome: mfd/cros_ec_dev: Add sysfs entry to set keyboard wake lid angle
This adds a sysfs attribute (/sys/class/chromeos/cros_ec/kb_wake_angle)
used to set and get the keyboard wake lid angle. This attribute is
present only if 2 accelerometers are controlled by the EC.

This patch also moves the cros_ec features check before the device is
added so the features map obtained from the EC is ready on time.

a9a08845e9 vfs: do bulk POLL* -> EPOLL* replacement
This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:

    for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
        L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
        for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
    done

with de-mangling cleanups yet to come.

NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do.  But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.

The next patch from Al will sort out the final differences, and we
should be all done.

b5856f97b3 regmap: Updates for v4.16
A very busy release for regmap, all fairly specialist stuff but useful:
 
  - Support for disabling locking from Bartosz Golaszewski, allowing
    users that handle their own locking to save some overhead.
  - Support for hwspinlocks in syscons in MFD from Baolin Wang, this is
    going through the regmap tree since the first users turned up some
    some cases that needed interface tweaks with 0 being used as a syscon
    identifier.
  - Support for devices with no read or write flag from Andrew F. Davis.
  - Basic support for devices on SoundWire buses from Vinod Koul.

The EC SPI driver prevents SPI transfers being to rapidly by keeping
track of the time the last transfer was issued via the
'last_transfer_ns' variable. Previously, if the 'last_transfer_ns'
variable was zero, this indicated that no previous transfer had been
sent and that no delay was needed. However, the EC SPI driver has
been updated to always initialise the 'last_transfer_ns' variable
during probe and therefore, it is no longer necessary to test if it
is zero. Remove the code that checks if this variable is zero.

107b7d9fa9 mfd: rtsx: Release IRQ during shutdown
'Commit cc27b735ad ("PCI/portdrv: Turn off PCIe services during
shutdown")' revealed a resource leak in rtsx_pci driver during shutdown.

Issue shows up as a warning during shutdown as follows:

remove_proc_entry: removing non-empty directory 'irq/17', leaking at least
'rtsx_pci'
WARNING: CPU: 0 PID: 1578 at fs/proc/generic.c:572
remove_proc_entry+0x11d/0x130
Modules linked in <long list but none that are out-of-tree>
...
Call Trace:
unregister_irq_proc

mp_unmap_irq
acpi_unregister_gsi_apic
acpi_pci_irq_disable
do_pci_disable_device
pci_disable_device
device_shutdown
kernel_restart
Sys_reboot

Even though rtsx_pci driver implements a shutdown callback, it is not
releasing the interrupt that it registered during probe. This is causing
the ACPI layer to complain that the shared IRQ is in use while freeing
IRQ.

This code releases the IRQ to prevent resource leak and eliminate the
warning.

39c3fd5895 kernel/irq: Extend lockdep class for request mutex
The IRQ code already has support for lockdep class for the lock mutex
in an interrupt descriptor. Extend this to add a second class for the
request mutex in the descriptor. Not having a class is resulting in
false positive splats in some code paths.

5e0115581b cros_ec: Move cros_ec_dev module to drivers/mfd
The cros_ec_dev module is responsible for registering the MFD devices
attached to the ChromeOS EC. This patch moves this module to drivers/mfd
so calls to mfd_add_devices() are not done from outside the MFD subtree
anymore.

ea01a31b90 cros_ec: Split cros_ec_devs module
This patch splits the cros_ec_devs module in two parts with a
cros_ec_dev module responsible for handling MFD devices registration and
a cros_ec_ctl module responsible for handling the various user-space
interfaces.

For consistency purpose, the driver name for the cros_ec_dev module is
now cros-ec-dev instead of cros-ec-ctl.

In the next commit, the new cros_ec_dev module will be moved to the MFD
subtree so mfd_add_devices() calls are not done from outside MFD.

001dde9400 mfd: cros ec: spi: Fix "in progress" error signaling
For host commands that take a long time to process, cros ec can return
early by signaling a EC_RES_IN_PROGRESS result. The host must then poll
status with EC_CMD_GET_COMMS_STATUS until completion of the command.

None of the above applies when data link errors are encountered. When
errors such as EC_SPI_PAST_END are encountered during command
transmission, it usually means the command was not received by the EC.
Treating such errors as if they were 'EC_RES_IN_PROGRESS' results is
almost always the wrong decision, and can result in host commands
silently being lost.

85e9b13cbb mfd: twl6040: Fix child-node lookup
Fix child-node lookup during probe, which ended up searching the whole
device tree depth-first starting at the parent rather than just matching
on its children.

To make things worse, the parent node was prematurely freed, while the
child node was leaked.

Note that the CONFIG_OF compile guard can be removed as
of_get_child_by_name() provides a !CONFIG_OF implementation which always
fails.

A helper purported to look up a child node based on its name was using
the wrong of-helper and ended up prematurely freeing the parent of-node
while leaking any matching node.

To make things worse, any matching node would not even necessarily be a
child node as the whole device tree was searched depth-first starting at
the parent.

15d8374874 mfd: cros ec: spi: Don't send first message too soon
On the Tegra124 Nyan-Big chromebook the very first SPI message sent to
the EC is failing.

The Tegra SPI driver configures the SPI chip-selects to be active-high
by default (and always has for many years). The EC SPI requires an
active-low chip-select and so the Tegra chip-select is reconfigured to
be active-low when the EC SPI driver calls spi_setup(). The problem is
that if the first SPI message to the EC is sent too soon after
reconfiguring the SPI chip-select, it fails.

The EC SPI driver prevents back-to-back SPI messages being sent too
soon by keeping track of the time the last transfer was sent via the
variable 'last_transfer_ns'. To prevent the very first transfer being
sent too soon, initialise the 'last_transfer_ns' variable after calling
spi_setup() and before sending the first SPI message.

and they bridge mmc subsystem and memstick subsystem, they are
not mfd drivers. Greg and Lee Jones had a discussion about
where to put the drivers, the result is that misc is a good
place for them, so I move all files to misc. If I don't move
them to a right place, I can't add any patch for this driver.

e99e88a9d2 treewide: setup_timer() -> timer_setup()
This converts all remaining cases of the old setup_timer() API into using
timer_setup(), where the callback argument is the structure already
holding the struct timer_list. These should have no behavioral changes,
since they just change which pointer is passed into the callback with
the same available pointers after conversion. It handles the following
examples, in addition to some other variations.

Casting from unsigned long:

    void my_callback(unsigned long data)
    {
        struct something *ptr = (struct something *)data;
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, ptr);

and forced object casts:

    void my_callback(struct something *ptr)
    {
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr);

become:

    void my_callback(struct timer_list *t)
    {
        struct something *ptr = from_timer(ptr, t, my_timer);
    ...
    }
    ...
    timer_setup(&ptr->my_timer, my_callback, 0);

Direct function assignments:

    void my_callback(unsigned long data)
    {
        struct something *ptr = (struct something *)data;
    ...
    }
    ...
    ptr->my_timer.function = my_callback;

have a temporary cast added, along with converting the args:

    void my_callback(struct timer_list *t)
    {
        struct something *ptr = from_timer(ptr, t, my_timer);
    ...
    }
    ...
    ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback;

And finally, callbacks without a data assignment:

    void my_callback(unsigned long data)
    {
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, 0);

have their argument renamed to verify they're unused during conversion:

    void my_callback(struct timer_list *unused)
    {
    ...
    }
    ...
    timer_setup(&ptr->my_timer, my_callback, 0);

The conversion is done with the following Coccinelle script:

spatch --very-quiet --all-includes --include-headers \
	-I ./arch/x86/include -I ./arch/x86/include/generated \
	-I ./include -I ./arch/x86/include/uapi \

4e4510fec4 sound updates for 4.15-rc1
There are no big surprising changes in this cycle, yet not too
 boring, either.  The biggest change from diffstat POV is the removal
 of the legacy OSS driver codes that have been already disabled for a
 long time.  This will bring a few trivial merge conflicts.
 
 As new features in ASoC side, there are two things: a new AC97 bus
 implementation and AMD Stony platform support.  Both include the
 relevant changes shared with other subsystems, e.g. AC97 MFD changes
 and DRM AMD changes.
 
 Some other highlighted topics are:
 - A bunch of USB-audio drivers got the hardening against the malicious
   device accesses with a new helper code for endpoint sanity check.
 - Lots of cleanups for ASoC Intel platform code, including support for
   their open source audio firmware.
 - Continued ASoC core componentization works.
 - Support for scaling MCLK with sample rate in ASoC simple-card.
 - Stabler PCM hot-unplug capability, especially for ASoC usages.

b24413180f License cleanup: add SPDX GPL-2.0 license identifier to files with no license
Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.

By default all files without license information are under the default
license of the kernel, which is GPL version 2.

Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier.  The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.

How this work was done:

Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
 - file had no licensing information it it.
 - file was a */uapi/* one with no licensing information in it,
 - file was a */uapi/* one with existing licensing information,

Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.

The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne.  Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.

The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed.  Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.

Criteria used to select files for SPDX license identifier tagging was:
 - Files considered eligible had to be source code files.
 - Make and config files were included as candidates if they contained >5
   lines of source
 - File already had some variant of a license header in it (even if <5
   lines).

All documentation files were explicitly excluded.

The following heuristics were used to determine which SPDX license
identifiers to apply.

 - when both scanners couldn't find any license traces, file was
   considered to have no license information in it, and the top level
   COPYING file license applied.

   For non */uapi/* files that summary was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0                                              11139

   and resulted in the first patch in this series.

   If that file was a */uapi/* path one, it was "GPL-2.0 WITH
   Linux-syscall-note" otherwise it was "GPL-2.0".  Results of that was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0 WITH Linux-syscall-note                        930

   and resulted in the second patch in this series.

 - if a file had some form of licensing information in it, and was one
   of the */uapi/* ones, it was denoted with the Linux-syscall-note if
   any GPL family license was found in the file or had no licensing in
   it (per prior point).  Results summary:

   SPDX license identifier                            # files
   ---------------------------------------------------|------
   GPL-2.0 WITH Linux-syscall-note                       270
   GPL-2.0+ WITH Linux-syscall-note                      169
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause)    21
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause)    17
   LGPL-2.1+ WITH Linux-syscall-note                      15
   GPL-1.0+ WITH Linux-syscall-note                       14
   ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause)    5
   LGPL-2.0+ WITH Linux-syscall-note                       4
   LGPL-2.1 WITH Linux-syscall-note                        3
   ((GPL-2.0 WITH Linux-syscall-note) OR MIT)              3
   ((GPL-2.0 WITH Linux-syscall-note) AND MIT)             1

   and that resulted in the third patch in this series.

 - when the two scanners agreed on the detected license(s), that became
   the concluded license(s).

 - when there was disagreement between the two scanners (one detected a
   license but the other didn't, or they both detected different
   licenses) a manual inspection of the file occurred.

 - In most cases a manual inspection of the information in the file
   resulted in a clear resolution of the license that should apply (and
   which scanner probably needed to revisit its heuristics).

 - When it was not immediately clear, the license identifier was
   confirmed with lawyers working with the Linux Foundation.

 - If there was any question as to the appropriate license identifier,
   the file was flagged for further research and to be revisited later
   in time.

In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.

Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights.  The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.

Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.

In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.

Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
 - a full scancode scan run, collecting the matched texts, detected
   license ids and scores
 - reviewing anything where there was a license detected (about 500+
   files) to ensure that the applied SPDX license was correct
 - reviewing anything where there was no detection but the patch license
   was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
   SPDX license was correct

This produced a worksheet with 20 files needing minor correction.  This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.

These .csv files were then reviewed by Greg.  Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected.  This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.)  Finally Greg ran the script using the .csv files to
generate the patches.

4d0ce62c0a i2c: gpio: Augment all boardfiles to use open drain
We now handle the open drain mode internally in the I2C GPIO
driver, but we will get warnings from the gpiolib that we
override the default mode of the line so it becomes open
drain.

We can fix all in-kernel users by simply passing the right
flag along in the descriptor table, and we already touched
all of these files in the series so let's just tidy it up.

b2e6355559 i2c: gpio: Convert to use descriptors
This converts the GPIO-based I2C-driver to using GPIO
descriptors instead of the old global numberspace-based
GPIO interface. We:

- Convert the driver to unconditionally grab two GPIOs
  from the device by index 0 (SDA) and 1 (SCL) which
  will work fine with device tree and descriptor tables.
  The existing device trees will continue to work just
  like before, but without any roundtrip through the
  global numberspace.

- Brutally convert all boardfiles still passing global
  GPIOs by registering descriptor tables associated with
  the devices instead so this driver does not need to keep
  supporting passing any GPIO numbers as platform data.

There is no stepwise approach as elegant as this, I
strongly prefer this big hammer over any antsteps for this
conversion. This way the old GPIO numbers go away and
NEVER COME BACK.

Special conversion for the different boards utilizing
I2C-GPIO:

- EP93xx (arch/arm/mach-ep93xx): pretty straight forward as
  all boards were using the same two GPIO lines, just define
  these two in a lookup table for "i2c-gpio" and register
  these along with the device. None of them define any
  other platform data so just pass NULL as platform data.
  This platform selects GPIOLIB so all should be smooth.
  The pins appear on a gpiochip for bank "G" as pins 1 (SDA)
  and 0 (SCL).

- IXP4 (arch/arm/mach-ixp4): descriptor tables have to
  be registered for each board separately. They all use
  "IXP4XX_GPIO_CHIP" so it is pretty straight forward.
  Most board define no other platform data than SCL/SDA
  so they can drop the #include of <linux/i2c-gpio.h> and
  assign NULL to platform data.

  The "goramo_mlr" (Goramo Multilink Router) board is a bit
  worrisome: it implements its own I2C bit-banging in the
  board file, and optionally registers an I2C serial port,
  but claims the same GPIO lines for itself in the board file.
  This is not going to work: there will be competition for the
  GPIO lines, so delete the optional extra I2C bus instead, no
  I2C devices are registered on it anyway, there are just hints
  that it may contain an EEPROM that may be accessed from
  userspace. This needs to be fixed up properly by the serial
  clock using I2C emulation so drop a note in the code.

- KS8695 board acs5k (arch/arm/mach-ks8695/board-acs5.c)
  has some platform data in addition to the pins so it needs to
  be kept around sans GPIO lines. Its GPIO chip is named
  "KS8695" and the arch selects GPIOLIB.

- PXA boards (arch/arm/mach-pxa/*) use some of the platform
  data so it needs to be preserved here. The viper board even
  registers two GPIO I2Cs. The gpiochip is named "gpio-pxa" and
  the arch selects GPIOLIB.

- SA1100 Simpad (arch/arm/mach-sa1100/simpad.c) defines a GPIO
  I2C bus, and the arch selects GPIOLIB.

- Blackfin boards (arch/blackfin/bf533 etc) for these I assume
  their I2C GPIOs refer to the local gpiochip defined in
  arch/blackfin/kernel/bfin_gpio.c names "BFIN-GPIO".
  The arch selects GPIOLIB. The boards get spiked with
  IF_ENABLED(I2C_GPIO) but that is a side effect of it
  being like that already (I would just have Kconfig select
  I2C_GPIO and get rid of them all.) I also delete any
  platform data set to 0 as it will get that value anyway
  from static declartions of platform data.

- The MIPS selects GPIOLIB and the Alchemy machine is using
  two local GPIO chips, one of them has a GPIO I2C. We need
  to adjust the local offset from the global number space here.
  The ATH79 has a proper GPIO driver in drivers/gpio/gpio-ath79.c
  and AFAICT the chip is named "ath79-gpio" and the PB44
  PCF857x expander spawns from this on GPIO 1 and 0. The latter
  board only use the platform data to specify pins so it can be
  cut altogether after this.

- The MFD Silicon Motion SM501 is a special case. It dynamically
  spawns an I2C bus off the MFD using sm501_create_subdev().
  We use an approach to dynamically create a machine descriptor
  table and attach this to the "SM501-LOW" or "SM501-HIGH"
  gpiochip. We use chip-local offsets to grab the right lines.
  We can get rid of two local static inline helpers as part
  of this refactoring.

18f7739379 mfd: fsl-imx25: Clean up irq settings during removal
When fsl-imx25-tsadc is compiled as a module, loading, unloading and
reloading the module will lead to a crash.

Unable to handle kernel paging request at virtual address bf005430
[<c004df6c>] (irq_find_matching_fwspec)
   from [<c028d5ec>] (of_irq_get+0x58/0x74)
[<c028d594>] (of_irq_get)
   from [<c01ff970>] (platform_get_irq+0x48/0xc8)
[<c01ff928>] (platform_get_irq)
   from [<bf00e33c>] (mx25_tsadc_probe+0x220/0x2f4 [fsl_imx25_tsadc])

irq_find_matching_fwspec() loops over all registered irq domains. The
irq domain is still registered from last time the module was loaded but
the pointer to its operations is invalid after the module was unloaded.

Add a removal function which clears the irq handler and removes the irq
domain. With this cleanup in place, it's possible to unload and reload
the module.

362741a21a mfd: mxs-lradc: Fix error handling in mxs_lradc_probe()
There is the only path, where mxs_lradc_probe() leaves clk undisabled,
since it does return instead of goto err_clk.

Found by Linux Driver Verification project (linuxtesting.org).

Avoton/Rangeley are based on Silvermount micro-architecture, like
Bay Trail, and uses the INTEL_SPI_BYT method to drive SPI.

b2b3adc93e mfd: tps65218: Introduce dependency on CONFIG_OF
Currently the driver boots only via device tree hence add a
dependency on CONFIG_OF. This leaves with a bunch of unused code
so clean that up.

8f76af65a5 mfd: tps65218: Correct the config description
When the initial support was added for this PMIC was added
only regulator support was present. Now we have GPIO and Powerbutton
support as well. Hence correct the description of MFD_TPS65218 config
option.
