On Odroid XU3 board (with S2MPS11 PMIC) the PWRHOLD bit in CTRL1
register must be manually set to 0 before initiating power off sequence.
One of usual power down methods for Exynos based devices looks like:
1. PWRHOLD pin of PMIC is connected to PSHOLD of Exynos SoC.
2. Exynos holds up this pin during system operation.
3. ACOKB pin of PMIC is pulled up to VBATT and optionally to pin in
other device.
4. When PWRHOLD/PSHOLD goes low, the PMIC will turn off the power if
ACOKB goes high.
On Odroid XU3 family the difference is in (3) - the ACOKB is grounded.
This means that PMIC must manually set PWRHOLD field to low and then
wait for signal from Application Processor (the usual change in
PWRHOLD/PSHOLD pin will actually cut off the power).
The patch adds respective binding allowing Odroid XU3 device to be
powered off.

There are already helper functions to do 64-bit I/O on 32-bit machines, thus we
don't need to reinvent the wheel. In our case we can't use readq() / writeq()
even on 64-bit kernel since there is a hardware limitation (OCP bus is a 32-bit
bus).

Commit 68bab8662f ("mfd: twl6040: Optional clk32k clock handling")
added clock handling for the 32k clock from palmas-clk. However, that
patch did not consider a typical situation where twl6040 is built-in,
and palmas-clk is a loadable module like we have in omap2plus_defconfig.
If palmas-clk is not loaded before twl6040 probes, we will get a
"clk32k is not handled" warning during booting. This means that any
drivers relying on this clock will mysteriously fail, including
omap5-uevm WLAN and audio.
Note that for WLAN, we probably should also eventually get
the clk32kgaudio for MMC3 directly as that's shared between
audio and WLAN SDIO at least for omap5-uevm. It seems the
WLAN chip cannot get it as otherwise MMC3 won't get properly
probed.

There are little changes in core part, but lots of development are
found in drivers, especially ASoC. The diffstat shows regmap-
related changes for a slight API additions / changes, and that's all.
Looking at the code size statistics, the most significant addition
is for Intel Skylake. (Note that SKL support is still underway, the
codec driver is missing.) Also STI controller driver is a major
addition as well as a few new codec drivers.
In HD-audio side, there are fewer changes than the past. The
noticeable change is the support of ELD notification from i915
graphics driver. Thus this pull request carries a few changes in
drm/i915.
Other than that, USB-audio got a rewrite of runtime PM code. It
was initiated by lockdep warning, but resulted in a good cleanup in
the end.
Below are the highlights:
Common:
- Factoring out of AC'97 reset code from ASoC into the core helper
- A few regmap API extensions (in case it's not pulled yet)
ASoC:
- New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek
RT298 and ST STI controllers
- Machine drivers for Rockchip systems with MAX98090 and RT5645 and
RT5650
- Initial driver support for Intel Skylake devices
- Lots of rsnd cleanup and enhancements
- A few DAPM fixes and cleanups
- A large number of cleanups in various drivers (conversion and
standardized to regmap, component) mostly by Lars-Peter and Axel
HD-audio:
- Extended HD-audio core for Intel Skylake controller support
- Quirks for Dell headsets, Alienware 15
- Clean up of pin-based quirk tables for Realtek codecs
- ELD notifier implenetation for Intel HDMI/DP
USB-audio:
- Refactor runtime PM code to make lockdep happier

Pull power management and ACPI updates from Rafael Wysocki:
"From the number of commits perspective, the biggest items are ACPICA
and cpufreq changes with the latter taking the lead (over 50 commits).
On the cpufreq front, there are many cleanups and minor fixes in the
core and governors, driver updates etc. We also have a new cpufreq
driver for Mediatek MT8173 chips.
ACPICA mostly updates its debug infrastructure and adds a number of
fixes and cleanups for a good measure.
The Operating Performance Points (OPP) framework is updated with new
DT bindings and support for them among other things.
We have a few updates of the generic power domains framework and a
reorganization of the ACPI device enumeration code and bus type
operations.
And a lot of fixes and cleanups all over.
Included is one branch from the MFD tree as it contains some
PM-related driver core and ACPI PM changes a few other commits are
based on.
Specifics:
- ACPICA update to upstream revision 20150818 including method
tracing extensions to allow more in-depth AML debugging in the
kernel and a number of assorted fixes and cleanups (Bob Moore, Lv
Zheng, Markus Elfring).
- ACPI sysfs code updates and a documentation update related to AML
method tracing (Lv Zheng).
- ACPI EC driver fix related to serialized evaluations of _Qxx
methods and ACPI tools updates allowing the EC userspace tool to be
built from the kernel source (Lv Zheng).
- ACPI processor driver updates preparing it for future introduction
of CPPC support and ACPI PCC mailbox driver updates (Ashwin
Chaugule).
- ACPI interrupts enumeration fix for a regression related to the
handling of IRQ attribute conflicts between MADT and the ACPI
namespace (Jiang Liu).
- Fixes related to ACPI device PM (Mika Westerberg, Srinidhi
Kasagar).
- ACPI device registration code reorganization to separate the
sysfs-related code and bus type operations from the rest (Rafael J
Wysocki).
- Assorted cleanups in the ACPI core (Jarkko Nikula, Mathias Krause,
Andy Shevchenko, Rafael J Wysocki, Nicolas Iooss).
- ACPI cpufreq driver and ia64 cpufreq driver fixes and cleanups (Pan

The biggest changes in the core this time around have been some
refactorings that move us towards being able to drop the list of
regulators maintained by the core and instead just use the driver model
list maintained for the class devices for regulators which will make the
code smaller and avoid some potential bugs. Otherwise another fairly
quiet release for the regulator API, highlights include:
- A new API for setting voltages based on a minimum, target, maximum
triplet.
- Support for continuous voltage ranges rather than tables of explicit
steps in the PWM regulator, requiring less explicit configuration.
- New driver support for Dialog DA9215, Maxim 77843, Mediatek MT6311
and Qualcomm RPM.

The MFD_CROS_EC symbol select CHROME_PLATFORMS and CROS_EC_PROTO but
that caused a Kconfig unmet direct dependencies warning since these
symbols could only be selected for X86 || ARM.
The fix it, the CHROME_PLATFORMS dependencies were relexed on commit
d12bbcd3ea ("platform/chrome: Don't make CHROME_PLATFORMS depends
on X86 || ARM") but that was found to be wrong and the correct fix
is to add the needed dependencies to the MFD_CROS_EC config symbol.
There are only x86 and ARM based Chromebooks so to avoid showing up
the config option on unsupported platforms, make the symbol depend on
these architectures. Also add a || COMPILE_TEST so it can have build
coverage on other platforms.

The ChromeOS EC SPI and I2C transport drivers depends on CROS_EC_PROTO
but MFD_CROS_EC select CROS_EC_PROTO instead. Mixing select and depends
on is bad practice as it may lead to circular Kconfig dependencies.
Since these drivers already depend on MFD_CROS_EC and that config option
already selects CROS_EC_PROTO, there is no need to make them explicitly
depend on CROS_EC_PROTO since that dependency is already met.

Add a cell for the usb power_supply part of the axp20x PMICs.
Note that this cell is only for the usb power_supply part and not the
ac-power / battery-charger / rtc-backup-bat-charger bits.
Depending on the board each of those must be enabled / disabled separately
in devicetree as most boards do not use all 4. So in dt each one needs its
own child-node of the axp20x node. Another reason for using separate child
nodes for each is so that other devicetree nodes can have a power-supply
property with a phandle referencing a node representing a single
power-supply.
The decision to use a separate devicetree node for each is reflected on
the kernel side by each getting its own mfd-cell / platform_device and
platform-driver.
Note this commit also makes some whitespace changes to the intialization
of existing cells in axp20x_cells, these are pure whitespace changes,
functionally nothing changes.

The I2C core always reports the MODALIAS uevent as "i2c:<client name"
regardless if the driver was matched using the I2C id_table or the
of_match_table. So technically there's no need for a driver to export
the OF table since currently it's not used.
In fact, the I2C device ID table is mandatory for I2C drivers since
a i2c_device_id is passed to the driver's probe function even if the
I2C core used the OF table to match the driver.
And since the I2C core uses different tables, OF-only drivers needs to
have duplicated data that has to be kept in sync and also the dev node
compatible manufacturer prefix is stripped when reporting the MODALIAS.
To avoid the above, the I2C core behavior may be changed in the future
to not require an I2C device table for OF-only drivers and report the
OF module alias. So, it's better to also export the OF table to prevent
breaking module autoloading if that happens.

IRQF_NOAUTOEN -> IRQ_NOAUTOEN
For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also modify IRQ_NOPROBE and this has been maintained although it
is not clear that is really needed. There appears to be a great deal of
blind copy and paste of this code.

The regmap register definitions have been a source of many small fixes
as issues are discovered. As such I made a small automated tool to
check these definitions. This patch fixes the issues (mostly harmless)
located by that tool, the issues fall into three catagories:
1) Volatile registers that have a default in the defaults table (default
has been removed from the table since it is redundant)
2) Registers that are marked as volatile but unreadable (register has
been removed from the volatile list since it is obviously not being
used)
3) Registers that arn't readable but have an entry in the defaults
table (again removed since it is redundant)
4) Readable non-volatile registers that are missing a default, these are
dangerous as they won't get synced during a cache sync. Fortunately,
most of them seem to be registers that shouldn't be there (for example
wm5102 had readable registers for DRC2 and ISRC3 which is doesn't have)
Hopefully another tool will be produced to check the actual default
values themselves but that is outside the scope of this patch.

The function arizona_irq_thread (the threaded handler for the arizona
IRQs) calls pm_runtime_get_sync at the start to ensure that the chip is
active as we handle the IRQ. If the chip is part way through a runtime
suspend when an IRQ arrives the PM core will wait for the suspend to
complete, before resuming. However, since commit 4f0216409f7c
("mfd: arizona: Add better support for system suspend") the runtime
suspend function may call disable_irq, if the chip is going to fully
power off, which will try to wait for any outstanding IRQs to complete.
This results in deadlock as the IRQ thread is waiting for the PM
operation to complete and the PM thread is waiting for the IRQ to
complete.
To avoid this situation we use disable_irq_nosync, which allows the
suspending thread to finish the suspend without waiting for the IRQ to
complete. This is safe because if an IRQ is being processed it can only
be blocked at the pm_runtime_get_sync at the start of the handler
otherwise it wouldn't be possible to suspend.

Intel Sunrisepoint (Skylake PCH) has the iTCO watchdog accessible across
the SMBus, unlike previous generations of PCH/ICH where it was on the
LPC bus. Because it's on the SMBus, it doesn't make sense to pass around
a 'struct lpc_ich_info', and leaking the type of bus into the iTCO
watchdog driver is kind of backwards anyway.
This change introduces a new 'struct itco_wdt_platform_data' for use
inside the iTCO watchdog driver and by the upcoming Intel Sunrisepoint
code, which neatly avoids having to include lpc_ich headers in the i801
i2c driver.
This change is overdue because lpc_ich_info has already found its way
into other TCO watchdog users, notably the intel_pmc_ipc driver where
the watchdog actually isn't on the LPC bus as far as I can see.
A simple translation layer is provided for converting from the existing
'struct lpc_ich_info' inside the lpc_ich mfd driver.

The twl4030 usb phy needs to be active while we are using
the USB VBUS as a current source for charging.
In particular, the usb3v1 regulator must be enabled and the
PHY_PWR_PHYPWD bit must be set to keep the phy powered.
commit ab37813f40
twl4030_charger: Allow charger to control the regulator that feeds it
gave the charger control over the regulator, but didn't resolve
the PHY_PWR_PHYPWD issue.
Now that both of these are controlled by runtime_pm in
phy-twl4030-usb, we can simply take a runtime_pm reference to the USB
phy whenever the charger wants to use it as a current source.
So this patch reverts the above commit, and adds the necessary
runtime_pm calls.

The PM runtime core by default assumes a chip is suspended when runtime
PM is enabled. Currently the arizona driver enables runtime PM when the
chip is fully active and then disables the DCVDD regulator at the end of
arizona_dev_init. This however has several problems, firstly the if we
reach the end of arizona_dev_init, we did not properly follow all the
proceedures for shutting down the chip, and most notably we never marked
the chip as cache only so any writes occurring between then and the next
PM runtime resume will be lost. Secondly, if we are already resumed when
we reach the end of dev_init, then at best we get unbalanced regulator
enable/disables at work we lose DCVDD whilst we need it.
Additionally, since the commit 4f0216409f7c ("mfd: arizona: Add better
support for system suspend"), the PM runtime operations may
disable/enable the IRQ, so the IRQs must now be enabled before we call
any PM operations.
This patch adds a call to pm_runtime_set_active to inform the PM core
that the device is starting up active and moves the PM enabling to
around the IRQ initialisation to avoid any PM callbacks happening until
the IRQs are initialised.

Separate the functionality using sequences of register writes from the
functions that take register defaults. This change renames the arguments
in order to support the extension of reg_sequence to take an optional
delay to be applied after any given register in a sequence is written.
This avoids adding an int to all register defaults, which could
substantially increase memory usage for regmaps with large default tables.
