Some newer Atom CPUs, eg Avoton and Bay Trail, use slightly different
register layouts for the iTCO than the current v1 and v2 iTCO.
Differences from previous iTCO versions include:
- The ACPI space is enabled in the "ACPI base address" register instead
of the "ACPI control register"
- The "no reboot" functionality is set in the "Power Management
Configuration" register instead of the "General Control and Status"
(GCS) register or PCI configuration space.
- The "ACPI Control Register" is not present on v3. The "Power
Management Configuration Base Address" register resides at the same
address is Avoton/Bay Trail.
To differentiate these newer chipsets create a new v3 iTCO version and
update the MFD driver to support them.

Not all revisions have all the clocks so get the necessary clocks

Also remove the dummy USB host clocks from the OMAP3 clock data.

The DBx500 and ABx500 should be getting their IRQs from the
device tree and nowhere else. Get rid of all the static assignments
everywhere, delete it from the driver, platform data and the
board files in one swift strike.
Lots of cross-dependencies in the MFD drivers for PRCMU and
AB8500 makes it necessary to strike everywhere at once to
eradicate IRQs passed as resources and platform data to the left
and right around the platform.

On the wm5102 the register patches are applied manually, rather than by
the regmap core. This application is wrapped in calls to
regcache_cache_bypass. However, this is dangerous as other threads may
be accessing the hardware at the same time as the pm_runtime operations
and if they do so during the period whilst cache_bypass is enabled those
writes will miss the cache when they shouldn't.
Apply the register patch using the new regmap_multi_reg_write_bypassed
function to avoid this problem. Also remove the call to
regcache_cache_bypass from the hardware patch application as it is
unneeded there and creates a similar window for writes to miss the
cache.

Currently the I2C device Ids conflict for the MFD and CODEC so
cannot be both instantiated on one platform. This patch updates
the Ids and names to make them unique from each other.
It should be noted that the I2C addresses for both PMIC and CODEC
are modifiable so instantiation of the two are kept as separate
devices, rather than instantiating the CODEC from the MFD code.

mfd_add_device() assigns .of_node in the device objects it creates only
if the mfd_cell for the device has the .of_compatible field set and the
DT node for the top-level MFD device contains a child whose compatible
property matches the cell's .of_compatible field.
This leaves .of_node unset in many cases. When this happens, entries in
the DT /aliases property which refer to the top-level MFD DT node will
never match the MFD child devices, hence causing the requested alias not
to be honored.
Solve this by setting each MFD child device's .of_node equal to the top-
level MFD device's .of_node field in the cases where it would otherwise
remain unset.
The first use-case for this will be aliases for the TPS6586x's RTC

Interrupts stop working after first resume initiated by them (e.g. by
RTC Alarm interrupt) because interrupt registers were not cleared properly.
When device is woken up from suspend by RTC Alarm, an interrupt occurs
before resuming I2C bus controller. The interrupt is handled by
regmap_irq_thread which tries to read RTC registers. This read fails
(I2C is still suspended) and RTC Alarm interrupt is disabled.

As an example of this is the audio block's ANAMICL register. In normal

The ADC driver always programs all possible ADC values and discards
them except for the value IIO asked for. On the am335x-evm the driver
programs four values and it takes 500us to gather them. Reducing the number
of conversations down to the (required) one also reduces the busy loop down
to 125us.
This leads to another error, namely the FIFOCOUNT register is sometimes
(like one out of 10 attempts) not updated in time leading to EBUSY.
The next read has the FIFOCOUNT register updated.
Checking for the ADCSTAT register for being idle isn't a good choice either.
The problem is that if TSC is used at the same time, the HW completes the
conversation for ADC *and* before the driver noticed it, the HW begins to
perform a TSC conversation and so the driver never seen the HW idle. The
next time we would have two values in the FIFO but since the driver reads
everything we always see the current one.
So instead of polling for the IDLE bit in ADCStatus register, we should
check the FIFOCOUNT register. It should be one instead of zero because we
request one value.
This change in turn leads to another error. Sometimes if TSC & ADC are
used together the TSC starts generating interrupts even if nobody
actually touched the touchscreen. The interrupts seem valid because TSC's
FIFO is filled with values for each channel of the TSC. This condition stops
after a few ADC reads but will occur again. Not good.
On top of this (even without the changes I just mentioned) there is a ADC
& TSC lockup condition which was reported to me by Jeff Lance including the
following test case:
A busy loop of "cat /sys/bus/iio/devices/iio\:device0/in_voltage4_raw"
and a mug on touch screen. With this setup, the hardware will lockup after
something between 20 minutes and it could take up to a couple of hours.
During that lockup, the ADCSTAT register says 0x30 (or 0x70) which means
STEP_ID = IDLE and FSM_BUSY = yes. That means the hardware says that it is
idle and busy at the same time which is an invalid condition.
For all this reasons I decided to rework this TSC/ADC part and add a
handshake / synchronization here:
First the ADC signals that it needs the HW and writes a 0 mask into the
SE register. The HW (if active) will complete the current conversation
and become idle. The TSC driver will gather the values from the FIFO
(woken up by an interrupt) and won't "enable" another conversation.
Instead it will wake up the ADC driver which is already waiting. The ADC
driver will start "its" conversation and once it is done, it will
enable the TSC steps so the TSC will work again.
After this rework I haven't observed the lockup so far. Plus the busy
loop has been reduced from 500us to 125us.
The continues-read mode remains unchanged.

The purpose of reg_se_cache has been defeated. It should avoid the
read-back of the register to avoid the latency and the fact that the
bits are reset to 0 after the individual conversation took place.
The reason why this is required like this to work, is that read-back of
the register removes the bits of the ADC so they do not start another
conversation after the register is re-written from the TSC side for the
update.
To avoid the not required read-back I introduce a "set once" variant which
does not update the cache mask. After the conversation completes, the
bit is removed from the SE register anyway and we don't plan a new
conversation "any time soon". The current set function is renamed to
set_cache to distinguish the two operations.
This is a small preparation for a larger sync-rework.

All OMAP IP blocks expect LE data, but CPU may operate in BE mode.
Need to use endian neutral functions to read/write h/w registers.
I.e instead of __raw_read[lw] and __raw_write[lw] functions code
need to use read[lw]_relaxed and write[lw]_relaxed functions.
If the first simply reads/writes register, the second will byteswap
it if host operates in BE mode.
Changes are trivial sed like replacement of __raw_xxx functions
with xxx_relaxed variant.

Remove sec_reg* helpers as they are not used anymore. These helpers were

Also the helpers didn't give any way of useful abstraction as they just

Rename old regmap field of "struct sec_pmic_dev" to "regmap_pmic" and
add new regmap for RTC.
On S5M8767A registers were not properly updated and read due to usage of
the same regmap as the PMIC. This could be observed in various hangs,
e.g. in infinite loop during waiting for UDR field change.
On this chip family the RTC has different I2C address than PMIC so
additional regmap is needed.

Lots of driver updates here plus some nice new core features, the main
one being the first:
- Enable support for providing a dummy regulator when we know that one
must exist for the device to be functional. This makes it much
easier to add regulator support to drivers since we don't require
that the machine integration for all systems using the device be
updated to provide regulators.
- Substantial reduction in the amount of busy waiting done while
waiting for enables to complete.
- Allow MFDs to distribute regulator supplies to child devices so we
don't have to expose the internal structure of MFDs outside of the
driver.
- Managed registeration for regulators.

Merge tag 'regulator-v3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator updates from Mark Brown:
"Lots of driver updates here plus some nice new core features, the main
one being the first:
- Enable support for providing a dummy regulator when we know that
one must exist for the device to be functional. This makes it much
easier to add regulator support to drivers since we don't require
that the machine integration for all systems using the device be
updated to provide regulators.
- Substantial reduction in the amount of busy waiting done while
waiting for enables to complete.
- Allow MFDs to distribute regulator supplies to child devices so we
don't have to expose the internal structure of MFDs outside of the
driver.
- Managed registeration for regulators"

If the first call to mfd_add_device() fails, no child devices have been
registered to the parent yet, and thus mfd_remove_devices() won't find
anything to remove nor free.
Hence the previously allocated array of atomic_t objects will leak.
Free the array instead of calling mfd_remove_devices() on failure during
the first loop iteration to fix this.

Commit 1e29af62f2 ("mfd: Add refcounting
support to mfd_cells") had to drop the "const" keyword on the "cell"
parameter of mfd_add_devices(), as it added the refcounting pointers
to the objects of the passed mfd_cell array itself.
However, the mfd core code operates on copies of the mfd_cell objects,
so there's no need to modify the originally passed objects.
Hence, move the setting of the refcounting pointers from mfd_add_devices()
to mfd_platform_add_cell(), where the copy of the mfd_cell objects is made.
mfd_clone_cell() can just pass (a copy of) the original usage_count
pointer.
This allows to make the "cell" parameter of mfd_add_devices() "const"
again, and avoids future race conditions when registering multiple
instances of the same device in parallel.

When we receive between 0x0000 and 0xFFFF (inclusive) from either
Platform Data or Device Tree, we should write the provided

should leave the device configuration at its default setting.

default settings according to simulation, but need to tune these
parameters after getting the real chip.

Pull MFD (multi-function device) updates from Samuel Ortiz:
"For the 3.12 merge window we have one new driver for the DA9063 PMIC
from Dialog Semiconductor.
Besides that driver we also have:
- Device tree support for the s2mps11 driver
- More devm_* conversion for the pm8921, max89xx, menelaus, tps65010,
wl1273 and pcf50633-adc drivers.
- A conversion to threaded IRQ and IRQ domain for the twl6030 driver.
- A fairly big update for the rtsx driver: Better power saving
support, better vendor settings handling, and a few fixes.
- Support for a couple more boards (COMe-bHL6 and COMe-cTH6) for the
Kontron driver.
- A conversion to the dev_get_platdata() API for all MFD drivers.
- A removal of non-DT (legacy) support for the twl6040 driver.
- A few fixes and additions (Mic detect level) to the wm5110 register

Error handling is on-its-head in this function. After invoking a function we
should examine the return code and return the error value if there was one.
Instead, this function checks for success and goes onto provide functionality
if success was received. Not so bad in a simple function like this, but in
a more complex one this could end up drowning in curly brackets.

Since the TWL6030 PMIC is used with OMAP4 SoCs only and OMAP4 legacy
boot is dropped there are no needs to allocate the range of IRQ
descriptors during system boot to support TWL6030 IRQs.
Hence, convert it to use linear irq_domain and move IRQ configuration in
.map()/.unmap() callbacks of irq_domain. So, IRQ mapping and descriptors
allocation will be performed dynamically basing on DT configuration.
The error message will be reported in case if unmapped IRQ is received by
TWL6030 (virq==0).

1) Removed request_irq() and replaced it with request_threaded_irq().
2) Removed generic_handle_irq() and replaced it with
handle_nested_irq().
Handling of these interrupts is nested, as we are handling an
interrupt (for e.g rtc, mmc1) when we are still servicing TWL irq.
3) Removed I2C read-retry logic for the case when twl_i2c_read() is
failed inside IRQ handler - there is no sense to do that, so just report
an error and return.
4) Each nested IRQ is configured with corresponding parent_irq,
which need to be retriggered in case if nested IRQ is marked
as IRQS_PENDING.

ADC is ideally expected to work at a frequency of 3MHz.
The present code had a check, which returned error if the frequency
went below the threshold value. But since AM335x supports various
working frequencies, this check is not required.
Now the code just uses the internal ADC clock divider to set the ADC
frequency w.r.t the sys clock.

Since enabling VMID takes a runtime PM reference there is no need to
suppress suspend when doing a runtime suspend. Similarly the digital
inputs and outputs are DAPM widgets and therefore the ASoC core will
be holding a reference for them.
This used to be required when integration with system suspend was being
bodged.

The performance of regmap-irq is improved if the interrupt mask registers
can be cached since it does read/modify/update cycles so start using the
register cache infrastructure for those registers. We should use this more
widely but I don't have a datasheet and this is a nice, conservative
starting point.

This patch clears all the events received while powering up DA9055.
While powering up DA9055, both power sequencer and gpio events are received.
These events remain uncleared after boot up, due to which further event handling
also fails. DA9055 has three event registers. The event register bits are set
to '1' on receiving an event. The events can be cleared on writing a '1' to
the set bit, which would then clear that bit to '0'. After applying this patch
we have a clean state after boot up.
