9af93db9e1 platform/x86: asus: Rename "fan mode" to "fan boost mode" 
The Asus WMI spec indicates that the function being controlled here
is called "Fan Boost Mode". The user-facing documentation also calls it
this.

The spec uses the term "fan mode" is used to refer to other things,
including functionality expected to appear on future products.
We missed this before as we are not dealing with the most readable of
specs, and didn't forsee any confusion around shortening the name.

Rename "fan mode" to "fan boost mode" to improve consistency with the
spec and to avoid a future naming conflict.

There is no interface breakage here since this has yet to be included
in an official kernel release. I also updated the kernel version listed
under ABI accordingly.

5516745311 platform-drivers-x86 for v5.3-1 
ASUS WMI driver got a big refactoring in order to support the TUF Gaming
 laptops. Besides that, the regression with backlight being permanently off
 on various EeePC laptops has been fixed.
 
 Accelerometer on HP ProBook 450 G0 shows wrong measurements due to
 X axis being inverted. This has been fixed.
 
 Intel PMC core driver has been extended to be ACPI enumerated
 if the DSDT provides device with _HID "INT33A1". This allows
 to convert the driver to be pure platform and support new hardware
 purely based on ACPI DSDT.
 
 From now on the Intel Speed Select Technology is supported thru
 a corresponding driver. This driver provides an access to the features
 of the ISST, such as Performance Profile, Core Power, Base frequency and
 Turbo Frequency.
 
 Mellanox platform drivers has been refactored and now extended
 to support more systems, including new coming ones.
 
 The OLPC XO-1.75 platform is now supported.
 
 CB4063 Beckhoff Automation board is using PMC clocks,
 provided via pmc_atom driver, for ethernet controllers in a way
 that they can't be managed by the clock driver. The quirk
 has been extended to cover this case.
 
 Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile
 the information of Chuwi Hi10 Air has been fixed to cover more models
 based on the same platform.
 
 Xiaomi notebooks have WMI interface enabled. Thus, the driver to support it
 has been provided. It required some extension of the generic WMI library,
 which allows to propagate opaque context to the ->probe() of the
 individual drivers.
 
 This release includes debugfs clean up from Greg KH for several drivers
 that drop return code check and make debugfs absence or failure non-fatal.
 
 Miscellaneous fixes here and there, mostly for Acer WMI and
 various Intel drivers.
 
 The listed below commits are duplicated due to previously pushed fixes in v5.2 cycle:
 - 1dd93f873d platform/x86: asus-wmi: Only Tell EC the OS will handle display hotkeys from asus_nb_wmi
 - 89ae3a0736 platform/x86: intel-vbtn: Report switch events when event wakes device
 - fa882fc80d platform/x86: mlx-platform: Fix parent device in i2c-mux-reg device registration

97ff4ca46d Char / Misc driver patches for 5.3-rc1 
Here is the "large" pull request for char and misc and other assorted
 smaller driver subsystems for 5.3-rc1.
 
 It seems that this tree is becoming the funnel point of lots of smaller
 driver subsystems, which is fine for me, but that's why it is getting
 larger over time and does not just contain stuff under drivers/char/ and
 drivers/misc.
 
 Lots of small updates all over the place here from different driver
 subsystems:
   - habana driver updates
   - coresight driver updates
   - documentation file movements and updates
   - Android binder fixes and updates
   - extcon driver updates
   - google firmware driver updates
   - fsi driver updates
   - smaller misc and char driver updates
   - soundwire driver updates
   - nvmem driver updates

Pull GPIO updates from Linus Walleij:
 "This is the big slew of GPIO changes for the v5.3 kernel cycle. This
  is mostly incremental work this time.

  Three important things:

   - The FMC subsystem is deleted through my tree. This happens through
     GPIO as its demise was discussed in relation to a patch decoupling
     its GPIO implementation from the standard way of handling GPIO. As
     it turns out, that is not the only subsystem it reimplements and
     the authors think it is better do scratch it and start over using
     the proper kernel subsystems than try to polish the rust shiny. See
     the commit (ACKed by the maintainers) for details.

   - Arnd made a small devres patch that was ACKed by Greg and goes into
     the device core.

   - SPDX header change colissions may happen, because at times I've
     seen that quite a lot changed during the -rc:s in regards to SPDX.
     (It is good stuff, tglx has me convinced, and it is worth the
     occasional pain.)

  Apart from this is is nothing controversial or problematic.

81a409bfd5 media: marvell-ccic: provide a clock for the sensor 
The sensor needs the MCLK clock running when it's being probed. On
platforms where the sensor is instantiated from a DT (MMP2) it is going
to happen asynchronously.

Therefore, the current modus operandi, where the bridge driver fiddles
with the sensor power and clock itself is not going to fly. As the comments
wisely note, this doesn't even belong there.

Luckily, the ov7670 driver is already able to control its power and
reset lines, we can just drop the MMP platform glue altogether.

It also requests the clock via the standard clock subsystem. Good -- let's
set up a clock instance so that the sensor can ask us to enable the clock.
Note that this is pretty dumb at the moment: the clock is hardwired to a
particular frequency and parent. It was always the case.

driver (used on OLPC XO-1, not present in DT) and set up appropriate

d308dfbf62 i2c: mux/i801: Switch to use descriptor passing 
This switches the i801 GPIO mux to use GPIO descriptors for
handling the GPIO lines. The previous hack which was reaching
inside the GPIO chips etc cannot live on. We pass descriptors
along with the GPIO mux device at creation instead.

The GPIO mux was only used by way of platform data with a
platform device from one place in the kernel: the i801 i2c bus
driver. Let's just associate the GPIO descriptor table with
the actual device like everyone else and dynamically create
a descriptor table passed along with the GPIO i2c mux.

This enables simplification of the GPIO i2c mux driver to
use only the descriptor API and the OF probe path gets
simplified in the process.

The i801 driver was registering the GPIO i2c mux with
PLATFORM_DEVID_AUTO which would make it hard to predict the
device name and assign the descriptor table properly, but
this seems to be a mistake to begin with: all of the
GPIO mux devices are hardcoded to look up GPIO lines from
the "gpio_ich" GPIO chip. If there are more than one mux,
there is certainly more than one gpio chip as well, and
then we have more serious problems. Switch to
PLATFORM_DEVID_NONE instead. There can be only one.

b096f626a6 platform/x86: asus-wmi: Switch fan boost mode 
The WMI exposes a write-only device ID where up to three fan modes can be
switched on some laptops (TUF Gaming FX505GM). There is a hotkey
combination Fn-F5 that does have a fan icon, which is designed to toggle
between fan modes. The DSTS of the device ID returns information about the
presence of this capability and the presence of each of the two additional
fan modes as a bitmask (0x01 - overboost present, 0x02 - silent present)
[1].

Add a SysFS entry that reads the last written value and updates value in
WMI on write and a hotkey handler that toggles the modes taking into
account their availability according to DSTS.

Modes:
* 0x00 - normal or balanced,
* 0x01 - overboost, increased fan RPM,
* 0x02 - silent, decreased fan RPM

e0668f2888 platform/x86: asus-wmi: Improve DSTS WMI method ID detection 
The DSTS method detection mistakenly selects DCTS instead of DSTS if
nothing is returned when the method ID is not defined in WMNB. As a result,
the control of keyboard backlight is not functional for TUF Gaming series
laptops. Implement detection based on _UID of the WMI device instead.

There is evidence that DCTS is handled by ACPI WMI devices that have _UID
ASUSWMI, whereas none of the devices without ASUSWMI respond to DCTS and
DSTS is used instead [1].

DSDT examples:

FX505GM (_UID ATK):
Method (WMNB, 3, Serialized)
{ ...
    If ((Local0 == 0x53545344))
    {
        ...
        Return (Zero)
    }
    ...
    // No return
}

K54C (_UID ATK):
Method (WMNB, 3, Serialized)
{ ...
    If ((Local0 == 0x53545344))
    {
        ...
        Return (0x02)
    }
    ...
    Return (0xFFFFFFFE)
}

c3bd15a078 ti-sysc interconnect target module driver changes for v5.3 
This series of changes improves probing devices with ti-sysc to the
 point where we can now probe most devices without the custom dts
 property "ti,hwmods" and no legacy platform data :)
 
 We add support for platform data callbacks for idling and unidling the
 clockdomain the module belongs to. The rest of the series mostly adds
 handling for the various quirks needed by old legacy modules such as
 i2c and watchdog. Some quirk handling is still missing for few modules,
 but those will be added as they get tested.
 
 The related platform data and dts changes will be sent separately.

4e23be473e bus: ti-sysc: Add support for module specific reset quirks 
Some older interconnect target modules need module internal clock
toggling quirks to reset properly. We've been doing this in the
platform code earlier, but need to be able to it directly in the
ti-sysc driver when we no longer rely on on the platform code.

Let's add reset handling for 1-wire, i2c and watchdog. Later on
we can add more modules like msdi and dss as they get tested.
For dra7 pcie, we should be able to just use the rstctrl reset
driver when available.

1210d1e6ba platform/chrome: wilco_ec: Add telemetry char device interface 
The Wilco Embedded Controller is able to send telemetry data
which is useful for enterprise applications. A daemon running on
the OS sends a command to the EC via a write() to a char device,
and can read the response with a read(). The write() request is
verified by the driver to ensure that it is performing only one
of the whitelisted commands, and that no extraneous data is
being transmitted to the EC. The response is passed directly
back to the reader with no modification.

The character device will appear as /dev/wilco_telemN, where N
is some small non-negative integer, starting with 0. Only one
process may have the file descriptor open at a time. The calling
userspace program needs to keep the device file descriptor open
between the calls to write() and read() in order to preserve the
response. Up to 32 bytes will be available for reading.

For testing purposes, try requesting the EC's firmware build
date, by sending the WILCO_EC_TELEM_GET_VERSION command with
argument index=3. i.e. write [0x38, 0x00, 0x03]
to the device node. An ASCII string of the build date is
returned.

The phylink conflict was between a bug fix by Russell King
to make sure we have a consistent PHY interface mode, and
a change in net-next to pull some code in phylink_resolve()
into the helper functions phylink_mac_link_{up,down}()

On the dp83867 side it's mostly overlapping changes, with
the 'net' side removing a condition that was supposed to
trigger for RGMII but because of how it was coded never

e0db94fe87 bus: ti-sysc: Make OCP reset work for sysstatus and sysconfig reset bits 
We've had minimal OCP softreset support in ti-sysc interconnect target
module driver only used for MCAN driver so far. But it turns out that
MCAN has the sysstatus register resetdone bit inverted compared to most
other modules.

Let's make OCP softreset work for other typical cases with reset status
in sysstatus or sysconfig register so we can use the new functions for
sysc_enable_module() and sysc_disable_module() without "ti,hwmods"
property in the following patches.

2b2f7def05 bus: ti-sysc: Add support for missing clockdomain handling 
We need to let ti-sysc driver manage clockdomain autoidle for the
duration of of reset, enable and idle. And we need to do it before we
enable the clock and after we disable it. Currently we are still
relying on platform callbacks indirectly managing clockdomain autoidle.
But I noticed that for device tree only probed drivers it now happens
only after we enabling the clocks and before we disable the clocks,
while it should be the other way around. So far I have not noticed
any issues with this though.

Let's add new ti_sysc_clkdm_deny_idle() and ti_sysc_clkdm_allow_idle()
functions for ti-sysc driver to use to manage clockdomains directly via
platform data callbacks. Note that we can implement the clockdomain
functions in pdata-quirks.c as for probing devices without "ti,hwmods"
custom property we don't need to use the other platform data callbacks.

Let's do this in one patch as there's is still an unlikely chance we
may need to apply this as a fix for v5.2 for dropping legacy platform
data for some devices. We also do have the option of adding back the
platform data if needed in case of trouble.

With .ndo_set_rx_mode/temac_set_multicast_list() being called in atomic
context (holding addr_list_lock), and temac_set_multicast_list() needing
to access temac indirect registers, the mutex used to synchronize indirect
register is a no-no.

Replace it with a spinlock, and avoid sleeping in
temac_indirect_busywait().

To avoid excessive holding of the lock, which is now a spinlock, the
temac_device_reset() function is changed to only hold the lock for short
periods.  With timeouts, it could be holding the spinlock for more than
2 seconds.

0c0b7ea23a platform/chrome: wilco_ec: Add property helper library 
A Property is typically a data item that is stored to NVRAM
by the EC. Each of these data items has an index associated
with it, known as the Property ID (PID). Properties may have
variable lengths, up to a max of WILCO_EC_PROPERTY_MAX_SIZE
bytes. Properties can be simple integers, or they may be more
complex binary data.

This patch adds support for getting and setting properties.
This will be useful for setting the charge algorithm and charge
schedules, which all use properties.

8fbce8efe1 backlight: lm3630a: Add firmware node support 
Add fwnode support to the lm3630a driver and optionally allow
configuring the label, default brightness level, and maximum brightness
level. The two outputs can be controlled by bank A and B independently
or bank A can control both outputs.

If the platform data was not configured, then the driver defaults to
enabling both banks. This patch changes the default value to disable
both banks before parsing the firmware node so that just a single bank
can be enabled if desired. There are no in-tree users of this driver.

Driver was tested on a LG Nexus 5 (hammerhead) phone.

8148c17b17 This is the bulk of the GPIO changes for the v5.2 kernel cycle: 
Core changes:
 - The gpiolib MMIO driver has been enhanced to handle two direction
   registers, i.e. one register to set lines as input and one register
   to set lines as output. It turns out some silicon engineer thinks
   the ability to configure a line as input and output at the same
   time makes sense, this can be debated but includes a lot of analog
   electronics reasoning, and the registers are there and need to
   be handled consistently. Unsurprisingly, we enforce the lines to
   be either inputs or outputs in such schemes.
 - Send in the proper argument value to .set_config() dispatched to
   the pin control subsystem. Nobody used it before, now someone
   does, so fix it to work as expected.
 - The ACPI gpiolib portions can now handle pin bias setting (pull up
   or pull down). This has been in the ACPI spec for years and we
   finally have it properly integrated with Linux GPIOs. It was based
   on an observation from Andy Schevchenko that Thomas Petazzoni's
   changes to the core for biasing the PCA950x GPIO expander actually
   happen to fit hand-in-glove with what the ACPI core needed.
   Such nice synergies happen sometimes.
 
 New drivers:
 - A new driver for the Mellanox BlueField GPIO controller. This is
   using 64bit MMIO registers and can configure lines as inputs
   and outputs at the same time and after improving the MMIO library
   we handle it just fine. Interesting.
 - A new IXP4xx proper gpiochip driver with hierarchical interrupts
   should be coming in from the ARM SoC tree as well.
 
 Driver enhancements:
 - The PCA053x driver handles the CAT9554 GPIO expander.
 - The PCA053x driver handles the NXP PCAL6416 GPIO expander.
 - Wake-up support on PCA053x GPIO lines.
 - OMAP now does a nice asynchronous IRQ handling on wake-ups by
   letting everything wake up on edges, and this makes runtime PM
   work as expected too.
 
 Misc:
 - Several cleanups such as devres fixes.
 - Get rid of some languager comstructs that cause problems when
   compiling with LLVMs clang.
 - Documentation review and update.

MIPS: SGI-IP27: use generic PCI driver 
Converted bridge code to a platform driver using the PCI generic driver
framework and use adding platform devices during xtalk scan. This allows
easier sharing bridge driver for other SGI platforms like IP30 (Octane) and
IP35 (Origin 3k, Fuel, Tezro).

Signed-off-by: Thomas Bogendoerfer <tbogendoerfer@suse.de>
[paul.burton@mips.com:
  - Leave __phys_to_dma(), __dma_to_phys() & pcibus_to_node() in
    arch/mips/pci/pci-ip27.c since the motivation for moving them
    disappeared when the driver stopped being moved to drivers/pci.]

487579bab8 platform/x86: asus-wmi: Add fn-lock mode switch support 
Some of latest ASUS laptops support new fn-lock mode switching.
This commit detect whether if the fn-lock option is enabled in
BIOS setting, and toggle the fn-lock mode via a new WMI DEVID
0x00100023 when the corresponding notify code captured.

The ASUS fn-lock mode switch is activated by pressing Fn+Esc.
When on, keys F1 to F12 behave as applicable, with meanings
defined by the application being used at the time. When off,
F1 to F12 directly triggers hardware features, well known audio
volume up/down, brightness up/down...etc, which were triggered
by holding down Fn key and F-keys.

Because there's no way to retrieve the fn-lock mode via existing
WMI methods per ASUS spec, driver need to initialize and keep the
fn-lock mode by itself.

8b95274784 net: macb: shrink macb_platform_data structure 
This structure was used intensively for machine specific values
when DT was not used. Since the removal of AVR32 from the kernel,
this structure is only used for passing clocks from PCI macb wrapper, all
other fields being 0.
All other known platforms use DT.

Remove the leftovers but make sure that PCI macb still works as
expected by using default values:
- phydev->irq is set to PHY_POLL by mdiobus_alloc()
- mii_bus->phy_mask is cleared while allocating it
- bp->phy_interface is set to PHY_INTERFACE_MODE_MII if mode not found
in DT.

This simplifies driver probe path and particularly phy handling.

I have maintained the 0x00000400 bit in TX_CHNL_CTRL.  It is specified as

f14f5c11f0 net: ll_temac: Support indirect_mutex share within TEMAC IP 
Indirect register access goes through a DCR bus bridge, which
allows only one outstanding transaction.  And to make matters
worse, each TEMAC IP block contains two Ethernet interfaces, and
although they seem to have separate registers for indirect access,
they actually share the registers.  Or to be more specific, MSW, LSW
and CTL registers are physically shared between Ethernet interfaces
in same TEMAC IP, with RDY register being (almost) specificic to
the Ethernet interface.  The 0x10000 bit in RDY reflects combined
bus ready state though.

So we need to take care to synchronize not only within a single
device, but also between devices in same TEMAC IP.

This commit allows to do that with legacy platform devices.

For OF devices, the xlnx,compound parent of the temac node should be
used to find siblings, and setup a shared indirect_mutex between them.
I will leave this work to somebody else, as I don't have hardware to
test that.  No regression is introduced by that, as before this commit
using two Ethernet interfaces in same TEMAC block is simply broken.

1895ef4ef2 This modernizes the IXP4xx platform and adds initial Device Tree 
Support. We migrate to MULTI_IRQ_HANDLER, bumps the IRQs to
 offset 16, converts to SPARSE_IRQ, then we add proper subsystem
 drivers in each subsystem for irqchip, GPIO and clocksource and
 switch over to using these new drivers.
 
 Next we modernize the NPE and QMGR drivers and push them down
 into drivers/soc.
 
 This has been tested on the IXP4xx NSLU2 and the Gateworks
 GW2358-4.

Merge tag 'ixp4xx-for-armsoc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik into arm/soc

This modernizes the IXP4xx platform and adds initial Device Tree
Support. We migrate to MULTI_IRQ_HANDLER, bumps the IRQs to
offset 16, converts to SPARSE_IRQ, then we add proper subsystem
drivers in each subsystem for irqchip, GPIO and clocksource and
switch over to using these new drivers.

Next we modernize the NPE and QMGR drivers and push them down
into drivers/soc.

This has been tested on the IXP4xx NSLU2 and the Gateworks
GW2358-4.

dfb6db007a ARM: ep93xx: keypad: stop using mach/platform.h 
We can communicate the clock rate using platform data rather than setting
a flag to use a particular value in the driver, which is cleaner and
avoids the dependency.

No platform in the kernel currently defines the ep93xx keypad device
structure, so this is a rather pointless excercise.  Any out of tree
users are probably dead now, but if not, they have to change their
platform code to match the new platform_data structure.

0065198e67 PM changes for am335x and am437x 
This series adds support for am437x RTC-only mode in suspend. In the
 RTC-only mode suspend, everything is shut down except the RTC. This
 makes the power consumption very low for suspend mode.
 
 To support RTC-only mode, we need to export omap_rtc_power_off_program()
 from the rtc driver and improve PM code to save and restore the wkup
 domain context. As RTC-only mode depends on the device being wired
 properly for things like memory, we need to also check for the machine
 type before we allow it. We also need to run DDR3 hardware leveling on
 resume.
 
 Note that there is a trivial merge conflict between the RTC branch
 and these changes where the RTC branch makes tm2bcd() a void function
 and the error handling parts can be just dropped.

 To do this, we improve ti-sysc driver not to rely on platform data
 callbacks to manage module clocks, and handle more quirks needed for
 some devices. Also few minor fixes are needed, but were considered
 not needed to be sent separately as they only show up with this series.
 
 Then we drop several thousands of lines of legacy platform data for
 omap4, omap5, dra7, am335x and am437x. We drop platform data for mmc,
 i2c, gpio and uart devices to start with as those are typically
 easily tested on all devices. In case of unexpected issues, we can just
 add back the legacy platform data for a single device type if needed.
 
 Finally we add initial support for enabling and disabling some devices
 without legacy platform data callbacks. I was planning on sending the
 dropping of legacy platform data as a separate series, but already
 applied Roger's patch on top and pushed it out.
 
 Note that this series depends on related SoC and is based on those.

14e14aaf61 platform/chrome: wilco_ec: Standardize mailbox interface 
The current API for the wilco EC mailbox interface is bad.

It assumes that most messages sent to the EC follow a similar structure,
with a command byte in MBOX[0], followed by a junk byte, followed by
actual data. This doesn't happen in several cases, such as setting the
RTC time, using the raw debugfs interface, and reading or writing
properties such as the Peak Shift policy (this last to be submitted soon).

Similarly for the response message from the EC, the current interface
assumes that the first byte of data is always 0, and the second byte
is unused. However, in both setting and getting the RTC time, in the
debugfs interface, and for reading and writing properties, this isn't
true.

The current way to resolve this is to use WILCO_EC_FLAG_RAW* flags to
specify when and when not to skip these initial bytes in the sent and
received message. They are confusing and used so much that they are
normal, and not exceptions. In addition, the first byte of
response in the debugfs interface is still always skipped, which is
weird, since this raw interface should be giving the entire result.

Additionally, sent messages assume the first byte is a command, and so
struct wilco_ec_message contains the "command" field. In setting or
getting properties however, the first byte is not a command, and so this
field has to be filled with a byte that isn't actually a command. This
is again inconsistent.

wilco_ec_message contains a result field as well, copied from
wilco_ec_response->result. The message result field should be removed:
if the message fails, the cause is already logged, and the callers are
alerted. They will never care about the actual state of the result flag.

These flags and different cases make the wilco_ec_transfer() function,
used in wilco_ec_mailbox(), really gross, dealing with a bunch of
different cases. It's difficult to figure out what it is doing.

Finally, making these assumptions about the structure of a message make
it so that the messages do not correspond well with the specification
for the EC's mailbox interface. For instance, this interface
specification may say that MBOX[9] in the received message contains
some information, but the calling code needs to remember that the first
byte of response is always skipped, and because it didn't set the
RESPONSE_RAW flag, the next byte is also skipped, so this information
is actually contained within wilco_ec_message->response_data[7]. This
makes it difficult to maintain this code in the future.

To fix these problems this patch standardizes the mailbox interface by:
- Removing the WILCO_EC_FLAG_RAW* flags
- Removing the command and reserved_raw bytes from wilco_ec_request
- Removing the mbox0 byte from wilco_ec_response
- Simplifying wilco_ec_transfer() because of these changes
- Gives the callers of wilco_ec_mailbox() the responsibility of exactly
  and consistently defining the structure of the mailbox request and
  response
- Removing command and result from wilco_ec_message.

This results in the reduction of total code, and makes it much more
maintainable and understandable.

e6818d29ea gpio: gpio-omap: configure edge detection for level IRQs for idle wakeup 
The GPIO block can enter idle independently of the CPU power management
calls via smart-idle.  When the GPIO block enters idle, level detection
stops working due to clocks being shut off, and an alternative form of
edge detection is used.  However, this needs the edge detection
registers set to mark the appropriate edges.

Arrange to configure the edge detection enables along with the level
detection to ensure that any transition to active interrupt state that
occurs while the block is idle is detected as a wake-up event.

Since we enable the edge detection when configuring the IRQ, both
omap2_gpio_enable_level_quirk() nor omap2_gpio_disable_level_quirk()
become redundant, which also means OMAP_GPIO_QUIRK_IDLE_REMOVE_TRIGGER
can be removed. This can be now done without regressions as patch
"gpio: gpio-omap: fix level interrupt idling" allows level interrupts
to idle on omap4 without a workaround.

386cb76681 bus: ti-sysc: Handle missed no-idle property in addition to no-idle-on-init 
We have ti,no-idle in use in addition to ti,no-idle-on-init but we're
missing handling for it in the ti-sysc interconnect target module driver.

Let's also group the idle defines together and update the binding
documentation for it.

b45a02e13e gpio: amd-fch: Fix bogus SPDX identifier 
spdxcheck.py complains:

 include/linux/platform_data/gpio/gpio-amd-fch.h: 1:28 Invalid License ID: GPL+

which is correct because GPL+ is not a valid identifier. Of course this
could have been caught by checkpatch.pl _before_ submitting or merging the
patch.

 WARNING: 'SPDX-License-Identifier: GPL+ */' is not supported in LICENSES/...
 #271: FILE: include/linux/platform_data/gpio/gpio-amd-fch.h:1:

Fix it under the assumption that the author meant GPL-2.0+, which makes
sense as the corresponding C file is using that identifier.

dc2535be1f We have a fairly balanced mix of clk driver updates and clk framework 
updates this time around. It's the usual pile of new drivers for new
 hardware out there and the normal small fixes and updates, but then we
 have some core framework changes too.
 
 In the core framework, we introduce support for a clk_get_optional() API
 to get clks that may not always be populated and a way to devm manage clkdev
 lookups registered by provider drivers. We also do some refactoring to simplify
 the interface between clkdev and the common clk framework so we can reuse the DT
 parsing and clk_get() path in provider drivers in the future. This work will
 continue in the next few cycles while we convert how providers specify clk
 parents.
 
 On the driver side, the biggest part of the dirstat is the Amlogic clk driver
 that got support for the G12A SoC. It dominates with almost half the overall
 diff, while the second largest part of the diff is in the i.MX clk driver
 that gained support for imx8mm SoCs. After that, we have the Actions Semiconductor
 and Qualcomm drivers rounding out the big part of the dirstat because they both
 got new hardware support for SoCs. The rest is just various updates and non-critical
 fixes for existing drivers.
 
 Core:
  - Convert a few clk bindings to JSON schema format
  - Add a {devm_}clk_get_optional() API
  - Add devm_clk_hw_register_clkdev() API to manage clkdev lookups
  - Start rewriting clk parent registration and supporting device links
    by moving around code that supports clk_get() and DT parsing of the
    'clocks' property
 
 New Drivers:
  - Add Qualcomm MSM8998 RPM managed clks
  - IPA clk support on Qualcomm RPMh clk controllers
  - Actions Semi S500 SoC clk support
  - Support for fixed rate clks populated from an MMIO register
  - Add RPC (QSPI/HyperFLASH) clocks on Renesas R-Car V3H
  - Add TMU (timer) clocks on Renesas RZ/G2E
  - Add Amlogic G12A Always-On Clock Controller
  - Add 32k clock generation for Amlogic AXG
  - Add support for the Mali GPU clocks on Amlogic Meson8
  - Add Amlogic G12A EE clock controller driver
  - Add missing CANFD clocks on Renesas RZ/G2M and RZ/G2E
  - Add i.MX8MM SoC clk driver support
 
 Removed Drivers:
  - Remove clps711x driver as the board support is gone
 
 Updates:
  - 3rd ECO fix for Mediatek MT2712 SoCs
  - Updates for Qualcomm MSM8998 GCC clks
  - Random static analysis fixes for clk drivers
  - Support for sleeping gpios in the clk-gpio type
  - Minor fixes for STM32MP1 clk driver (parents, critical flag, etc.)
  - Split LCDC into two clks on the Marvell MMP2 SoC
  - Various DT of_node refcount fixes
  - Get rid of CLK_IS_BASIC from TI code (yay!)
  - TI Autoidle clk support
  - Fix Amlogic Meson8 APB clock ID name
  - Claim input clocks through DT for Amlogic AXG and GXBB
  - Correct the DU (display unit) parent clock on Renesas RZ/G2E
  - Exynos5433 IMEM CMU crypto clk support (SlimSS)
  - Fix for the PLL-MIPI on the Allwinner A23
  - Fix Rockchip rk3328 PLL rate calculation
  - Add SET_RATE_PARENT flag on display clk of Rockhip rk3066
  - i.MX SCU clk driver clk_set_parent() and cpufreq support

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.

aebbfafc74 ARM: SoC platform updates for 5.1 
The APM X-Gene platform is now maintained by folks from Ampere
 computing that took over the product line a while ago, this gets
 reflected in the MAINTAINERS file.
 
 Cleanups continue on the older mach-davinci and mach-pxa platform,
 to get them to be more like the modern ones. For pxa, we
 now remove the Raumfeld platform code as it now works with
 device tree based booting.
 
 i.MX adds a couple new features for the i.MX7ULP SoC
 
 Mediatek gains support for a new SoC: MT7629 is a new wireless
 router platform, following MT7623.
 
 Aside from those, there are the usual minor cleanups and bugfixes
 across several platforms.

0d2f2a3da1 platform/chrome: wilco_ec: Add RTC driver 
This Embedded Controller has an internal RTC that is exposed
as a standard RTC class driver with read/write functionality.

The driver is added to the drivers/rtc/ so that the maintainer of that
directory will be able to comment on this change, as that maintainer is
the expert on this system. In addition, the driver code is called
indirectly after a corresponding device is registered from core.c,
as opposed to core.c registering the driver callbacks directly.

To test:

69da8be90d dmaengine: dw: Split DW and iDMA 32-bit operations 
Here is a kinda big refactoring that should have been done
in the first place, when Intel iDMA 32-bit support appeared.

It splits operations which are different to Synopsys DesignWare and
Intel iDMA 32-bit controllers.

No functional change intended.

0781657796 dmaengine: dw: Remove unused internal property 
All known devices, which use DT for configuration, support
memory-to-memory transfers. So enable it by default.

The rest two cases, i.e. Intel Quark and PPC460ex, instantiate DMA driver and
use its channels exclusively for hardware, which means there is no available
channel for any other purposes anyway.

d7dba6be0f dmaengine: dw: Remove misleading is_private property 
The commit a9ddb575d6

   ("dmaengine: dw_dmac: Enhance device tree support")

introduces is_private property in uncertain understanding what does it mean.

First of all, documentation defines DMA_PRIVATE capability as

Documentation/crypto/async-tx-api.txt:
  The DMA_PRIVATE capability flag is used to tag dma devices that should not be
  used by the general-purpose allocator. It can be set at initialization time
  if it is known that a channel will always be private. Alternatively,
  it is set when dma_request_channel() finds an unused "public" channel.

  A couple caveats to note when implementing a driver and consumer:
  1/ Once a channel has been privately allocated it will no longer be
     considered by the general-purpose allocator even after a call to
     dma_release_channel().
  2/ Since capabilities are specified at the device level a dma_device with
     multiple channels will either have all channels public, or all channels
     private.

Documentation/driver-api/dmaengine/provider.rst:
  - DMA_PRIVATE
    The devices only supports slave transfers, and as such isn't available
    for async transfers.

The capability had been introduced by the commit 59b5ec2144

  ("dmaengine: introduce dma_request_channel and private channels")

and some code didn't changed from that times ever.

Taking into consideration above and the fact that on all known platforms
Synopsys DesignWare DMA engine is attached to serve slave transfers,
the DMA_PRIVATE capability must be enabled for this device unconditionally.
Otherwise, as rightfully noticed in drivers/dma/at_xdmac.c:
  /*
   * Without DMA_PRIVATE the driver is not able to allocate more than
   * one channel, second allocation fails in private_candidate.
   */
because of of a caveats mentioned in above documentation excerpts.

So, remove conditional around DMA_PRIVATE followed by removal leftovers.

If someone wonders, DMA_PRIVATE can be not used if and only if the all channels
of the DMA controller are supposed to serve memory-to-memory like operations.
For example, EP93xx has two controllers, one of which can only perform
memory-to-memory transfers

Note, this change doesn't affect dmatest to be able to test such controllers.

f54005b508 mmc: pxa: Use GPIO descriptor for power 
After converting the PXA driver to use GPIO descriptors for
card detect and write protect it is relatively simple to
convert it to also use a descriptor for getting the optional
power control GPIO.

The polarity inversion flag can also go away from the platform
data since this is indicated in the GPIO machine descriptor
table.

80a68f387c mmc: pxamci: Delete platform data handling of CD and WP 
This deletes the code dealing with handling card detect
and write protect passed in as platform data and makes
the host rely on just GPIO descriptors.

The card read only inversion flag has to be kept around
for now, as the core cannot handle the inversion flags
on the descriptors yet.

Since we can now rely on the descriptors to have the
right polarity, we set the "override_active_level" to
false in mmc_gpiod_request_cd() and mmc_gpiod_request_ro().

d2951dfa07 mmc: s3cmci: Use the slot GPIO descriptor 
Simplify things by making the S3CMCI driver just use
slot GPIO with descriptors instead of passing around the
global GPIO numbers that we want to get rid of.

Getting the names of the GPIO chips into the machine
descriptor tables was a bit of a challenge but I think
I have them right.

The platform data supports passing in inversion flags, but
no platform is using them, and it is highly unlikely
that we will add more, so drop them. The long term plan
is to let the inversion flags on the GPIO machine
descriptor do the job.

The lines are flagged as GPIO_ACTIVE_[LOW|HIGH] as that is
what they are, and since we can now rely on the descriptors
to have the right polarity, we set the
"override_active_level" to false in mmc_gpiod_request_cd()
and mmc_gpiod_request_ro().

4cc1feeb6f Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net 
Several conflicts, seemingly all over the place.

I used Stephen Rothwell's sample resolutions for many of these, if not
just to double check my own work, so definitely the credit largely
goes to him.

The NFP conflict consisted of a bug fix (moving operations
past the rhashtable operation) while chaning the initial
argument in the function call in the moved code.

The net/dsa/master.c conflict had to do with a bug fix intermixing of
making dsa_master_set_mtu() static with the fixing of the tagging
attribute location.

cls_flower had a conflict because the dup reject fix from Or
overlapped with the addition of port range classifiction.

__set_phy_supported()'s conflict was relatively easy to resolve
because Andrew fixed it in both trees, so it was just a matter
of taking the net-next copy.  Or at least I think it was :-)

Joe Stringer's fix to the handling of netns id 0 in bpf_sk_lookup()
intermixed with changes on how the sdif and caller_net are calculated
in these code paths in net-next.

The remaining BPF conflicts were largely about the addition of the
__bpf_md_ptr stuff in 'net' overlapping with adjustments and additions
to the relevant data structure where the MD pointer macros are used.

dc9d38cec7 net: phy: mdio-gpio: Add phy_ignore_ta_mask to platform data 
The Marvell 6390 Ethernet switch family does not perform MDIO
turnaround correctly. Many hardware MDIO bus masters don't care about
this, but the bitbangging implementation in Linux does by default. Add
phy_ignore_ta_mask to the platform data so that the bitbangging code
can be told which devices are known to get TA wrong.

04fa26bab0 net: phy: mdio-gpio: Add platform_data support for phy_mask 
It is sometimes necessary to instantiate a bit-banging MDIO bus as a
platform device, without the aid of device tree.

When device tree is being used, the bus is not scanned for devices,
only those devices which are in device tree are probed. Without device
tree, by default, all addresses on the bus are scanned. This may then
find a device which is not a PHY, e.g. a switch. And the switch may
have registers containing values which look like a PHY. So during the
scan, a PHY device is wrongly created.

After the bus has been registered, a search is made for
mdio_board_info structures which indicates devices on the bus, and the
driver which should be used for them. This is typically used to
instantiate Ethernet switches from platform drivers.  However, if the
scanning of the bus has created a PHY device at the same location as
indicated into the board info for a switch, the switch device is not
created, since the address is already busy.

This can be avoided by setting the phy_mask of the mdio bus. This mask
prevents addresses on the bus being scanned.

786a9ab133 gpio: davinci: restore a way to manually specify the GPIO base 
Commit 587f7a694f ("gpio: davinci: Use dev name for label and
automatic base selection") broke the network support in legacy boot
mode for da850-evm since we can no longer request the MDIO clock GPIO.

Other boards may be broken too, which I haven't tested.

The problem is in the fact that most board files still use the legacy
GPIO API where lines are requested by numbers rather than descriptors.

While this should be fixed eventually, in order to unbreak the board
for now - provide a way to manually specify the GPIO base in platform
data.

7b0c03ecc4 dmaengine: dw-dmac: implement dma protection control setting 
This patch adds a new device-tree property that allows to
specify the dma protection control bits for the all of the
DMA controller's channel uniformly.

Setting the "correct" bits can have a huge impact on the
PPC460EX and APM82181 that use this DMA engine in combination
with a DesignWare' SATA-II core (sata_dwc_460ex driver).

In the OpenWrt Forum, the user takimata reported that:
|It seems your patch unleashed the full power of the SATA port.
|Where I was previously hitting a really hard limit at around
|82 MB/s for reading and 27 MB/s for writing, I am now getting this:
|
|root@OpenWrt:/mnt# time dd if=/dev/zero of=tempfile bs=1M count=1024
|1024+0 records in
|1024+0 records out
|real    0m 13.65s
|user    0m 0.01s
|sys     0m 11.89s
|
|root@OpenWrt:/mnt# time dd if=tempfile of=/dev/null bs=1M count=1024

|1024+0 records out
|real    0m 8.41s
|user    0m 0.01s
|sys     0m 4.70s
|
|This means: 121 MB/s reading and 75 MB/s writing!
|
|The drive is a WD Green WD10EARX taken from an older MBL Single.
|I repeated the test a few times with even larger files to rule out
|any caching, I'm still seeing the same great performance. OpenWrt is
|now completely on par with the original MBL firmware's performance.

Another user And.short reported:
|I can report that your fix worked! Boots up fine with two
|drives even with more partitions, and no more reboot on
|concurrent disk access!

A closer look into the sata_dwc_460ex code revealed that
the driver did initally set the correct protection control
bits. However, this feature was lost when the sata_dwc_460ex
driver was converted to the generic DMA driver framework.

  - Tidy up pattern mask generation.
  - Read regulator when scale is requested (which should be infrequent)
    as it might have changed from initialization.

  - Don't use a busy_pin for ad7818 as there isn't one.

1be7aa9b6e Input: ad7879 - drop platform data support 
This driver supports configuration via platform data but
absolutely nothing in the upstream kernel uses it. Since this
configuration allows harmful practices such as encoding the
GPIO base for the chip, delete platform data support so that
no new platform using it gets introduced.

Also: include the right driver header, not <linux/gpio.h>.

4b42745211 ARM: SoC platform updates for 4.20 
A couple of platforms change hands in the MAINTAINERS file:
 
 - Linus Walleij lists himself for the ARM Reference platforms:
   versatile, vexpress, integrator and realview. He has been the main
   contributor for these for a while, and makes it official now.
 
 - Vladimir Zapolskiy takes over the LPC18xx platform from Joachim Eastwood
 
 - Manivannan Sadhasivam becomes a secondary maintainer for the
   Actions Semi machines
 
 - Nicolas Ferre lists updates the MAINTAINER listing for the AT91
   platform: Ludovic Desroches is now a co-maintainer for the platform, and
   several other people (Claudiu Beznea, Cristian Birsan, Eugen Hristev,
   Codrin Ciubotariu) take over individual device drivers.
 
 Thanks everyone for working on this, and welcome to the new maintainers!
 
 The "virt" platform on qemy or kvm can now be used in big-endian mode
 without additional tricks, thanks to Jason Donenfeld.
 
 Once again, we gain support for another NXP i.MX6 variant, this time
 it's the i.MX 6ULZ 32-bit single-core version.
 
 On arm64, we add support for two SoCs from Renesas: RZ/G2E (r8a774c0)
 and RZ/G2M (r8a774a1). These are described as microcontrollers on the
 manufacturer website, but appear to be rather powerful. The RZ/G2M is
 used on the reference board for the CIP Super Long Term Support (SLTS)
 Linux Kernels.

b22b6beae6 ARM: SoC driver updates for 4.17 
The most noteworthy SoC driver changes this time include:
 
 - The TEE subsystem gains an in-kernel interface to access the TEE
   from device drivers.
 
 - The reset controller subsystem gains a driver for the Qualcomm
   Snapdragon 845 Power Domain Controller.
 
 - The Xilinx Zynq platform now has a firmware interface for its
   platform management unit. This contains a firmware "ioctl" interface
   that was a little controversial at first, but the version we merged
   solved that by not exposing arbitrary firmware calls to user space.
 
 - The Amlogic Meson platform gains a "canvas" driver that is used
   for video processing and shared between different high-level drivers.
 
 The rest is more of the usual, mostly related to SoC specific power
 management support and core drivers in drivers/soc:
 
 - Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
   features related to power and reset control.
 
 - The Mediatek mt8183 and mt6765 SoC platforms gain support for
   their respective power management chips.
 
 - A new driver for NXP i.MX8, which need a firmware interface for
   power management.
 
 - The SCPI firmware interface now contains support estimating power
   usage of performance states
 
 - The NVIDIA Tegra "pmc" driver gains a few new features, in particular
   a pinctrl interface for configuring the pads.
 
 - Lots of small changes for Qualcomm, in particular the "smem"
   device driver.
 
 - Some cleanups for the TI OMAP series related to their sysc
   controller.
 
 Additional cleanups and bugfixes in SoC specific drivers include the
 Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms.

114b5f8f7e This is the bulk of GPIO changes for the v4.20 series: 
Core changes:
 
 - A patch series from Hans Verkuil to make it possible to
   enable/disable IRQs on a GPIO line at runtime and drive GPIO
   lines as output without having to put/get them from scratch.
   The irqchip callbacks have been improved so that they can
   use only the fastpatch callbacks to enable/disable irqs
   like any normal irqchip, especially the gpiod_lock_as_irq()
   has been improved to be callable in fastpath context.
   A bunch of rework had to be done to achieve this but it is
   a big win since I never liked to restrict this to slowpath.
   The only call requireing slowpath was try_module_get() and
   this is kept at the .request_resources() slowpath callback.
   In the GPIO CEC driver this is a big win sine a single
   line is used for both outgoing and incoming traffic, and
   this needs to use IRQs for incoming traffic while actively
   driving the line for outgoing traffic.
 
 - Janusz Krzysztofik improved the GPIO array API to pass a
   "cookie" (struct gpio_array) and a bitmap for setting or
   getting multiple GPIO lines at once. This improvement
   orginated in a specific need to speed up an OMAP1 driver and
   has led to a much better API and real performance gains
   when the state of the array can be used to bypass a lot
   of checks and code when we want things to go really fast.
   The previous code would minimize the number of calls
   down to the driver callbacks assuming the CPU speed was
   orders of magnitude faster than the I/O latency, but this
   assumption was wrong on several platforms: what we needed
   to do was to profile and improve the speed on the hot
   path of the array functions and this change is now
   completed.
 
 - Clean out the painful and hard to grasp BNF experiments
   from the device tree bindings. Future approaches are looking
   into using JSON schema for this purpose. (Rob Herring
   is floating a patch series.)
 
 New drivers:
 
 - The RCAR driver now supports r8a774a1 (RZ/G2M).
 
 - Synopsys GPIO via CREGs driver.
 
 Major improvements:
 
 - Modernization of the EP93xx driver to use irqdomain and
   other contemporary concepts.
 
 - The ingenic driver has been merged into the Ingenic pin
   control driver and removed from the GPIO subsystem.
 
 - Debounce support in the ftgpio010 driver.

e63201f194 mmc: omap_hsmmc: Delete platform data GPIO CD and WP 
The OMAP HSMMC driver has some elaborate and hairy handling for
passing GPIO card detect and write protect lines from a boardfile
into the driver: the machine defines a struct omap2_hsmmc_info
that is copied into struct omap_hsmmc_platform_data by
omap_hsmmc_pdata_init() in arch/arm/mach-omap2/hsmmc.c.

However the .gpio_cd and .gpio_wp fields are not copied from
omap2_hsmmc_info to omap_hsmmc_platform_data by
omap_hsmmc_pdata_init() so they remain unused. The only platform
defining omap2_hsmmc_info also define both to -1, unused.

It turn out there are no boardfiles passing any valid GPIO
lines into the OMAP HSMMC driver at all. And since we are not
going to add any more OMAP2 boardfiles, we can delete this
card detect and write protect handling altogether.

This seems to also fix a bug: the card detect callback
mmc_gpio_get_cd() in the slot GPIO core needs to be called
by drivers utilizing slot GPIO. It appears the the boardfile
quirks were not doing this right, so this would only get
called for boardfiles, i.e. since no boardfile was using it,
never.

Just assign mmc_gpio_get_cd() unconditionally to omap_hsmmc_ops
.get_cd() so card detects from the device tree works.
AFAICT card detect with GPIO lines assigned from
mmc_of_parse() are not working at the moment, but that is
no regression since it probably never worked.

7838a8ddc8 mmc: omap_hsmmc: Kill off cover detection 
Cover detection appears to be a feature protecting the SD
card on mobile phones with a slide-cover, such as some Nokia
phones. The idea seems to be to not allow access to the
SD card when the cover is open.

It is only usable with platform data from board files, but
no board file in the kernel is using it, yet it takes up
a sizeable chunk of code in the OMAP HSMMC driver.

Since we do not add new board files for the OMAPs any target
that need this should anyway reimplement it properly using
the device tree, so delete this legacy code.

The driver is marked as orphan in MAINTAINERS by the way.

The platform data for the PXAv3 driver allows passing a card

In order to not encourage the use of the old global GPIO
numberspace we need to remove this.

Card detect (and write protect) GPIO can easily be added into
the driver using machine descriptor tables instead, and the
descriptor-based (gpiod) variants of the slot GPIO APIs.

 need to be detected to set legacy quirks.
 
 We also add support for booting am335x, am437x and dra7 SoCs with L4 devices
 defined in device tree instead of legacy platform data.
 
 And finally we simplify suspend with just SET_NOIRQ_SYSTEM_SLEEP_PM_OPS
 and dropping the custom functions that were attempting to work around
 issues that really turned out to be child device driver related issues.
 
 Apologies for a late pull request, debugging the suspend issues took a while

40d9f91248 bus: ti-sysc: Defer suspend as needed 
We don't care when we suspend but some our children do. In order to
avoid tagging various modules with SYSC_QUIRK_RESOURCE_PROVIDER, let's
do it automatically by tagging modules that are busy on suspend for
noirq suspend. This way we can just do module detection on define DEBUG.

Note that we still need to keep SYSC_QUIRK_LEGACY_IDLE flag around so
the our legacy single-child devices that set pm_runtime_irq_safe() can
manage the interconnect target module themselves.

b764a5863f gpio: omap: Remove custom PM calls and use cpu_pm instead 
For a long time the gpio-omap custom PM calls have been annoying me so
let's replace them with cpu_pm instead. This will enable GPIO PM for
deeper idle states on omap4. And we can handle GPIO PM for omap2/3/4
in the same way.

Note that with this patch we are also slightly changing GPIO PM to be
less aggressive for omap3 and only will idle GPIO when PER context
may be lost.

For omap2, we don't need to save context and don't want to remove any
triggering so let's add a quirk flag for that.

Let's do this all in a single patch to avoid a situation where old
custom calls still are used with new code.

ec0daae685 gpio: omap: Add level wakeup handling for omap4 based SoCs 
I noticed that unlike omap2 and 3 based SoCs, omap4 based SoCs keep
the GPIO clocks enabled for GPIO level interrupts with wakeup enabled.
This blocks deeper idle states as the whole domain will stay busy.

The GPIO functional clock seems to stay enabled if the wakeup register
is enabled and a level interrupt is triggered. In that case the only
way to have the GPIO module idle is to reset it. It is possible this
has gone unnoticed with OSWR (Open SWitch Retention) and off mode
during idle resetting GPIO context most GPIO instances in the earlier
Android trees for example.

Looks like the way to deal with this is to have omap4 based SoCs
only set wake for the duration of idle for level interrupts, and clear
level registers for the idle. With level interrupts we can do this as
the level interrupt from device will be still there on resume.

I've taken the long path to fixing this to avoid yet more hard to
read code. I've set up a quirks flag, and a struct for function
pointers so we can use these to clean up other quirk handling easier
in the later patches. The current level quirk handling is moved to
the new functions.
