When the axp288_charger driver was originally merged, it was merged with
a dependency on some other driver providing platform data for it.
However the battery-data-framework which should provide that data never
got merged, so the axp288_charger as merged upstream has never worked,
its probe method simply always returns -ENODEV.
This commit removes the dependency on the platform_data instead reading
back the charging current and charging voltage that the firmware has set
and using those values as the maximum values the user may set.

As usual, we queue up a few fixes that don't seem urgent enough to go in
through -rc, or that just came a little too late given their size.
The zx fixes make the platform finally boot on real hardware, the
davinci and imx31 get the DT support working better for some of
the machines that are still normally used with classic board files.
One tegra fix is important for new bootloader versions, but the
bug has been around for a while without anyone noticing.
The other changes are mostly cosmetic.

Not as big as 4.9 was, but still just over a thousand changes. We
almost broke even of lines added vs. removed, as the slicoss driver was
removed (got a "clean" driver for the same hardware through the netdev

adding a few thousand lines to the source tree in the end. Other than
that it's a lot of minor fixes all over the place, nothing major stands

Rework the IRQ handler by using HW IRQ number and status bit.
Each HW IRQ number is matched with TPS65217 register layout[*].
(USB IRQ number is 0, AC is 1, Push button is 2)
When an interrupt is enabled, mask bit should be cleared (unmasked).
If an interrupt is disabled, then mask bit should be set (masked).
This mask value is updated into the TPS65217 register in irq_sync_unlock().
Mask bit and interrupt status bit can be handled with HW IRQ number.
Eventually, additional IRQ data, 'tps65217_irqs[]' and the function,
'irq_to_tps65217_irq()' are not necessary.

The AXP806 supports either master/standalone or slave mode.
Slave mode allows sharing the serial bus, even with multiple
AXP806 which all have the same hardware address.
This is done with extra "serial interface address extension",
or AXP806_BUS_ADDR_EXT, and "register address extension", or
AXP806_REG_ADDR_EXT, registers. The former is read-only, with
1 bit customizable at the factory, and 1 bit depending on the
state of an external pin. The latter is writable. Only when
the these device addressing bits (in the upper 4 bits of the
registers) match, will the device respond to operations on
its other registers.
Add these 2 registers to the regmap so we can access them.

Enum value of 'tps65217_irq_type' is not matched with DT parsed hwirq
number[*].
The MFD driver gets the IRQ data by referencing hwirq, but the value is
different. So, irq_to_tps65217_irq() returns mismatched IRQ data.
Eventually, the power button driver enables not PB but USB interrupt
when it is probed.
According to the TPS65217 register map[**], USB interrupt is the LSB.
This patch defines synchronized IRQ value.

Add the core functions to be able to support the sensors attached behind
the ChromeOS Embedded Controller and used by other IIO cros-ec sensor
drivers.
The cros_ec_sensor_core driver matches with current driver in ChromeOS
4.4 tree, so it includes all the fixes at the moment. The support for
this driver was made by Gwendal Grignou. The original patch and all the
fixes has been squashed and rebased on top of mainline.

Subsystem improvements:
- Do away with the last users of the obsolete Kconfig options
ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB (the latter
always sounded like an item on a wishlist to Santa Claus to
me). We can now select GPIOLIB and be done with it, for all
archs. After some struggle it even work on UM. Not that it has
GPIO, but if it wants to, it can select the library.
- Continued efforts to make drivers properly either tristate or
bool.
- Introduce a warning for drivers assigning default triggers to
their irqchip lines when probed from device tree, so we find and
fix these ambigous drivers. It is agreed that in the OF config
path, the device tree defines trigger characteristics.
- The same warning, mutatis mutandis, for ACPI-probed GPIO
irqchips.
- We introduce the ability to mark certain IRQ lines as "unusable"
as they can be taken by BIOS/firmware, unrouted in silicon and
generally nasty if you use them, and such things. This is
put to good use in the STMPE driver and also in the Cherryview
pin control driver.
- A new "mockup" virtual GPIO device that can be used for testing.
The plan is to add unit tests under tools/* for exercising this
device and verify that the kernel code paths are working as they
should.
- Make memory-mapped I/O-drivers depend on HAS_IOMEM. This was
implicit all the time, but when people started building UM
with allyesconfig or allmodconfig it exploded in their face.
- Move some stray bits of device tree and ACPI HW description
callbacks down into their respective implementation silo. These
were causing issues when compiling on !HAS_IOMEM as well, so
now eventually UM compiles the GPIOLIB library if it wants to.
New drivers:
- New driver for the Aspeed GPIO front-end companion to the
pin controller merged through the pin control tree.
- New driver for the LP873x PMIC GPIO portions.
- New driver for Technologic Systems' I2C FPGA GPIO such as
TS4900, TS-7970, TS-7990 and TS-4100.
- New driver for the Broadcom BCM63xx series including BCM6338
and BCM6345.
- New driver for the Intel WhiskeyCove PMIC GPIO.
- New driver for the Allwinner AXP209 PMIC GPIO portions.
- New driver for Diamond Systems 48 line GPIO-MM, another of
these port-mapped I/O expansion cards.
- Support the STMicroelectronics STMPE1600 variant in the STMPE
driver.
Driver improvements:
- The STMPE driver now supports rising/falling edge detection
properly for IRQs.
- The PCA954x will now fetch and enable its VCC regulator properly.
- Major rework of the PCA953x driver with the goal of eventually
switching it over to use regmap and thus modernize it even more.
- Switch the IOP driver to use the generic MMIO GPIO library.
- Move the ages old HTC EGPIO (extended GPIO) GPIO expander driver
over to this subsystem from MFD, achieveing some separation of
concerns.

Due to the lack of parity in the way array fields have been named/
numbered, a mistake was made where more debug fields were declared
than actually existed. In doing so, 2 fields were added, which
although unclear, were already declared in the array. The result
was that the latter declarations trashed the former ones.
This patch places the array back in the correct order and removes
the offending NULL entries.
While we're at it, let's ensure this doesn't happen again by naming
each field properly and add a new *_LAST define to describe how
many fields there should be.

When building with -Woverride-init, we get a warning about an incorrect
initializer:
drivers/mfd/rk808.c:244:8: error: initialized field overwritten [-Werror=override-init]
[RK818_IRQ_DISCHG_ILIM] = {
This is clearly a mistake, as both RK818_IRQ_DISCHG_ILIM and RK818_IRQ_USB_OV
are defined as '7', but they refer to different register bits. Changing
RK818_IRQ_DISCHG_ILIM to 15 is consistent with how all other 14 interrupts are
handled here, so I'm assuming this is what it should have been.

The X-Powers AXP806 is a new PMIC that is paired with Allwinner's A80
SoC, along with a master AXP809 PMIC.
This PMIC has a new register layout, and supports some functions not
seen in other X-Powers PMICs, such as master-slave mode, or having
multiple AXP806 PMICs on the same bus with address space extension,
or supporting both I2C and RSB mode. I2C has not been tested.
This patch adds support for the interrupts of the PMIC. A regulator
sub-device is enabled, but actual regulator support will come in a
later patch.

Newer revisions of the ChromeOS EC add more events besides the keyboard
ones. So handle interrupts in the MFD driver and let consumers register
for notifications for the events they might care.
To keep backward compatibility, if the EC doesn't support MKBP event, we
fall back to the old MKBP key matrix host command.

Now that open delay and sample delay for each channel is configurable
via DT, the default IDLE_TIMEOUT value is not enough as this is
calculated based on hardcoded macros. This results in driver returning
EBUSY sometimes. Fix this by increasing the timeout
value based on maximum value possible to open delay and sample delays
for each channel.

Create a new header file for TI DA8XX SoC CFGCHIPx registers.
This will be used by a number of planned drivers including a new USB
PHY driver and common clock framework drivers.
The same defines *will* be removed from the platform_data header,
once all the users start using the new syscon device header.
This also fixes the following compiler error caused due to
a dependent patch not merged.

this update allows to use registers map as following :
regs[reg_index + offset] instead of
regs[reg_index] + offset
This makes code clearer and will facilitate the addition of STMPE1600
on which LSB and MSB registers are respectively located at addr and addr + 1.
Despite for all others STMPE variant, LSB and MSB registers are respectively
located in reverse order at addr + 1 and addr.
For variant which have 3 registers's bank, we use LSB,CSB and MSB indexes
which contains respectively LSB (or LOW), CSB (or MID) and MSB (or HIGH)
register addresses (STMPE1801/STMPE24xx).
For variant which have 2 registers's bank, we use LSB and CSB indexes only.
In this case the CSB index contains the MSB regs address (STMPE 1601).

As STMPE1801/1601/24xx has a SYS_CTRL register and
STMPE1601/2403 has even a SYS_CTRL2 register, add
STMPE_IDX_SYS_CTRL/2 and update driver code accordingly
This update prepares the ground for not yet supported STMPE1600

This set of changes improve some aspects of the atomic API as well as
make use of this new API in the regulator framework to allow properly
dealing with critical regulators controlled by a PWM.
Aside from that there's a bunch of updates and cleanups for existing
drivers, as well as the addition of new drivers for the Broadcom iProc,
STMPE and ChromeOS EC controllers.

The EC_CMD_PWM_{GET,SET}_DUTY commands allow us to control a PWM that is
attached to the EC, rather than the main host SoC. The API provides
functionality-based (e.g., keyboard light, backlight) or index-based
addressing of the PWM(s). Duty cycles are represented by a 16-bit value,
where 0 maps to 0% duty cycle and U16_MAX maps to 100%. The period
cannot be controlled.
This command set is more generic than, e.g.,
EC_CMD_PWM_{GET,SET}_KEYBOARD_BACKLIGHT and could possibly used to
replace it on future products.
Let's update the command header to include the definitions.

On some boards, like omap5-uevm the MCLK is gated by default and in order
to be able to use the High performance modes of twl6040 it need to be
enabled by SW.
Add support for handling the MCLK source clock via CCF.
At the same time lower the print priority of the notification that the 32K
clock is not provided and it is not going to be handled by the driver.

Currently the hi655x-pmic driver has names for interrupt mask

So to allow for interrupt numbers to have sane names, rename

TPS65218 has a pre-defined power-up / power-down sequence which in
a typical application does not need to be changed. However, it is possible
to define custom sequences under I2C control. The power-up sequence is
defined by strobes and delay times. Each output rail is assigned to a
strobe to determine the order in which the rails are enabled.
Every regulator has sequence registers and every regulator has a default
strobe value and gets disabled when a particular power down sequence
occurs.
To keep a regulator on during suspend we write value 0 to strobe so
that the regulator is out of all sequencers and is not impacted by any
power down sequence. Hence saving the default strobe value during probe
so that when we want to regulator to be enabled during suspend we write 0
to strobe and when we want it to get disabled during suspend we write
the default saved strobe value.
This allows platform data to specify which power rails should be on or off
during RTC only suspend. This is necessary to keep DDR state while in RTC
only suspend.

Prevent memory scribble by checking that ioctl buffer size parameters
are sane.
Without this check, on 32 bits system, if .insize = 0xffffffff - 20 and
.outsize the amount to scribble, we would overflow, allocate a small
amounts and be able to write outside of the malloc'ed area.
Adding a hard limit allows argument checking of the ioctl. With the
current EC, it is expected .insize and .outsize to be at around 512 bytes
or less.

RCar Gen2 and later implementations of TMIO/SDHI have their own set of
features and additions. FAST_CLK_CHG is just one of them and I see a few
others being added soon. Some may work on older chipsets but this needs
to be tested case by case. Instead of adding a bunch of flags for each
feature, add a global RCar2+ one for now. We can still break out
features if the need arises.

This patch adds support for MIPI DPHYs found in Exynos5420-compatible

earlier by different offset of MIPI DPHY registers in PMU controllers
(Exynos 5420-compatible case) or by moving MIPI DPHY reset registers to
separate system register controllers (Exynos 5433 case). In both case
also additional 5th PHY (MIPI CSIS 2) has been added.

Driver did not provide default value for ramp delay for LDOs which lead
to warning in dmesg, e.g. on Odroid XU4:
[ 1.486076] vdd_ldo9: ramp_delay not set
[ 1.506875] vddq_mmc2: ramp_delay not set
[ 1.523766] vdd_ldo15: ramp_delay not set
[ 1.544702] vdd_sd: ramp_delay not set
The datasheet for all the S2MPS1x family is inconsistent here and does
not specify unambiguously the value of ramp delay for LDO. It mentions
30 mV/us in one timing diagram but then omits it completely in LDO
regulator characteristics table (it is specified for bucks).
However the vendor kernels for Galaxy S5 and Odroid XU3 use values of 12
mV/us or 24 mV/us.
Without the ramp delay value the consumers do not wait for voltage
settle after changing it. Although the proper value of ramp delay for
LDOs is unknown, it seems safer to use at least some value from
reference kernel than to leave it unset.

LD06 on the AS3722 power management IC supports a bypass mode. Bypass
is enabled for the LDO by writing the value 0x3F to the voltage select
field in the control register for the LDO. Note that this is the same
register and field that is used to select the voltage as well for the
LDO.
Add support for bypass on LDO6 by specifying the various bypass
parameters for regulator and adding new function pointer tables for the
LDO. Note that the bypass OFF value is the same as the ON value simply
because there is no actual OFF value and bypass will be disabled when
a new voltage is written to the VSEL field.

Since device_add_property_set() now always takes a copy of
the property_set, and also since the fwnode type is always
hard coded to be FWNODE_PDATA, there is no need for the
drivers to deliver the entire struct property_set. The
function can just create the instance of it on its own and
bind the properties from the drivers to it on the spot.
This renames device_add_property_set() to
device_add_properties(). The function now takes struct
property_entry as its parameter instead of struct
property_set.

The buck9 regulator of S2MPS11 PMIC had incorrect vsel_mask (0xff
instead of 0x1f) thus reading entire register as buck9's voltage. This
effectively caused regulator core to interpret values as higher voltages
than they were and then to set real voltage much lower than intended.
The buck9 provides power to other regulators, including LDO13
and LDO19 which supply the MMC2 (SD card). On Odroid XU3/XU4 the lower
voltage caused SD card detection errors on Odroid XU3/XU4:
mmc1: card never left busy state
mmc1: error -110 whilst initialising SD card
During driver probe the regulator core was checking whether initial
voltage matches the constraints. With incorrect vsel_mask of 0xff and
default value of 0x50, the core interpreted this as 5 V which is outside
of constraints (3-3.775 V). Then the regulator core was adjusting the
voltage to match the constraints. With incorrect vsel_mask this new
voltage mapped to a vere low voltage in the driver.

- Fix ABI regression of MMC BLK ioctl
- Remove the unused MMC_DATA_STREAM flag
- Enable asynchronous system PM for the host device
- Minor fixes and clean-ups
SDHCI host:
Throughout the years, the numbers of SDHCI variants have increased and so
has also the numbers of SDHCI callbacks/quirks. The purpose of these
callbacks/quirks were to enable SDHCI to deal with variant specific
requirements, but unfortunate this method didn't scale. Instead we have
ended up with a mess. Not only did the code become suboptimal but also
highly fragile.
Lately many discussions of how to move forward with SDHCI has taken place
at the MMC mailing list. Step by step, we aim to turn SDHCI's common code
into a set of library functions. This will enable for optimizations and
allow some of the existing callbacks/quirks to be removed, which also
should help to make the code less fragile.
Therefore I am also really pleased to announce that Adrian Hunter (Intel)
has volunteered to step in as the maintainer for SDHCI.
Future wise, I hope the community around SDHCI will continue to grow and
that this release cycle can be the starting point of moving SDHCI into a
better shape. As a matter of fact, already in this cycle the re-factoring
has begun, but of course there are also fixes and new features included.
Some highlights:
- sdhci-iproc: Add support for Broadcom's BCM2835 eMMC IP
- sdhci-acpi: Add support for QCOM controllers
- sdhci-pic32: Add new SDHCI variant for PIC32MZDA
Other hosts:
- atmel-mci: Fix a NULL pointer dereference
- mediatek: Add SD write-protect support
- mmc_spi: Fix card detect in GPIO case
- tmio/sdhi: Add r8a7795 support

Pull MMC updates from Ulf Hansson:
"MMC core:
- Fix ABI regression of MMC BLK ioctl
- Remove the unused MMC_DATA_STREAM flag
- Enable asynchronous system PM for the host device
- Minor fixes and clean-ups
SDHCI host:
Throughout the years, the numbers of SDHCI variants have increased
and so has also the numbers of SDHCI callbacks/quirks. The purpose
of these callbacks/quirks were to enable SDHCI to deal with variant
specific requirements, but unfortunate this method didn't scale.
Instead we have ended up with a mess. Not only did the code become
suboptimal but also highly fragile.
Lately many discussions of how to move forward with SDHCI has taken
place at the MMC mailing list. Step by step, we aim to turn
SDHCI's common code into a set of library functions. This will
enable for optimizations and allow some of the existing callbacks
and quirks to be removed, which also should help to make the code
less fragile.
Therefore I am also really pleased to announce that Adrian Hunter
(Intel) has volunteered to step in as the maintainer for SDHCI.
Future wise, I hope the community around SDHCI will continue to
grow and that this release cycle can be the starting point of
moving SDHCI into a better shape. As a matter of fact, already in
this cycle the re-factoring has begun, but of course there are also
fixes and new features included. Some highlights:
- sdhci-iproc: Add support for Broadcom's BCM2835 eMMC IP
- sdhci-acpi: Add support for QCOM controllers
- sdhci-pic32: Add new SDHCI variant for PIC32MZDA
Other hosts:
- atmel-mci: Fix a NULL pointer dereference
- mediatek: Add SD write-protect support
- mmc_spi: Fix card detect in GPIO case
- tmio/sdhi: Add r8a7795 support

Core changes:
- The gpio_chip is now a *real device*. Until now the gpio chips
were just piggybacking the parent device or (gasp) floating in
space outside of the device model. We now finally make GPIO chips
devices. The gpio_chip will create a gpio_device which contains
a struct device, and this gpio_device struct is kept private.
Anything that needs to be kept private from the rest of the kernel
will gradually be moved over to the gpio_device.
- As a result of making the gpio_device a real device, we have added
resource management, so devm_gpiochip_add_data() will cut down on
overhead and reduce code lines. A huge slew of patches convert
almost all drivers in the subsystem to use this.
- Building on making the GPIO a real device, we add the first step
of a new userspace ABI: the GPIO character device. We take small
steps here, so we first add a pure *information* ABI and the tool
"lsgpio" that will list all GPIO devices on the system and all
lines on these devices. We can now discover GPIOs properly from
userspace. We still have not come up with a way to actually *use*
GPIOs from userspace.
- To encourage people to use the character device for the future,
we have it always-enabled when using GPIO. The old sysfs ABI is
still opt-in (and can be used in parallel), but is marked as
deprecated. We will keep it around for the foreseeable future,
but it will not be extended to cover ever more use cases.
Cleanup:
- Bjorn Helgaas removed a whole slew of per-architecture <asm/gpio.h>
includes. This dates back to when GPIO was an opt-in feature and
no shared library even existed: just a header file with proper
prototypes was provided and all semantics were up to the arch to
implement. These patches make the GPIO chip even more a proper
device and cleans out leftovers of the old in-kernel API here
and there. Still some cruft is left but it's very little now.
- There is still some clamping of return values for .get() going
on, but we now return sane values in the vast majority of drivers
and the errorpath is sanitized. Some patches for powerpc, blackfin
and unicore still drop in.
- We continue to switch the ARM, MIPS, blackfin, m68k local GPIO
implementations to use gpiochip_add_data() and cut down on code
lines.
- MPC8xxx is converted to use the generic GPIO helpers.
- ATH79 is converted to use the generic GPIO helpers.
New drivers:
- WinSystems WS16C48
- Acces 104-DIO-48E
- F81866 (a F7188x variant)
- Qoric (a MPC8xxx variant)
- TS-4800

To make RTC block of MAX77686/MAX77802 as independent driver,
move the registration of i2c device, regmap for register access
and irq_chip for interrupt support inside the RTC driver.
Removed the same initialisation from MFD driver.
Having this change will allow to reuse this driver for different
PMIC/devices from Maxim Semiconductor if they kept same RTC IP on
different PMIC. Some of examples as PMIC MAX77620, MAX20024 where
same RTC IP used and hence driver for these chips will use this
driver only for RTC support.

The axp20x driver assumes the device is i2c based. This is not the
case with later chips, which use a proprietary 2 wire serial bus
by Allwinner called "Reduced Serial Bus".
This patch follows the example of mfd/wm831x and splits it into
an interface independent core, and an i2c specific glue layer.
MFD_AXP20X and the new MFD_AXP20X_I2C are changed to tristate
symbols, allowing the driver to be built as modules.
Whitespace and other style errors in the moved i2c specific code
have been fixed. Included but unused header files are removed as
well.

Aside from a fix for a spurious warning (which caused more problems than
it fixed in the fixing really) this is all driver updates, including new
drivers for Dialog PV88060/90 and TI LM363x and TPS65086 devices. The

- Add a debugfs-based interface for interacting with the ACPICA's
AML debugger introduced in the previous cycle and a new user
space tool for that, fix some bugs related to the AML debugger
and clean up the code in question (Lv Zheng, Dan Carpenter,
Colin Ian King, Markus Elfring).
- Update ACPICA to upstream revision 20151218 including a number
of fixes and cleanups in the ACPICA core (Bob Moore, Lv Zheng,
Labbe Corentin, Prarit Bhargava, Colin Ian King, David E Box,
Rafael Wysocki).
In particular, the previously added erroneous support for the
_SUB object is dropped, the concatenate operator will support
all ACPI objects now, the Debug Object handling is improved,
the SuperName handling of parameters being control methods is
fixed, the ObjectType operator handling is updated to follow
ACPI 5.0A and the handling of CondRefOf and RefOf is updated
accordingly, module-level code will be executed after loading
each ACPI table now (instead of being run once after all tables
containing AML have been loaded), the Operation Region handlers
management is updated to fix some reported problems and a the
ACPICA code in the kernel is more in line with the upstream
now.
- Update the ACPI backlight driver to provide information on
whether or not it will generate key-presses for brightness
change hotkeys and update some platform drivers (dell-wmi,
thinkpad_acpi) to use that information to avoid sending double
key-events to users pace for these, add new ACPI backlight
quirks (Hans de Goede, Aaron Lu, Adrien Schildknecht).
- Improve the ACPI handling of interrupt GPIOs (Christophe Ricard).
- Fix the handling of the list of device IDs of device objects
found in the ACPI namespace and add a helper for checking if
there is a device object for a given device ID (Lukas Wunner).
- Change the logic in the ACPI namespace scanning code to create
struct acpi_device objects for all ACPI device objects found in
the namespace even if _STA fails for them which helps to avoid
device enumeration problems on Microsoft Surface 3 (Aaron Lu).
- Add support for the APM X-Gene ACPI I2C device to the ACPI
driver for AMD SoCs (Loc Ho).
- Fix the long-standing issue with the DMA controller on Intel
SoCs where ACPI tables have no power management support for
the DMA controller itself, but it can be powered off automatically
when the last (other) device on the SoC is powered off via ACPI
and clean up the ACPI driver for Intel SoCs (acpi-lpss) after
previous attempts to fix that problem (Andy Shevchenko).
- Assorted ACPI fixes and cleanups (Andy Lutomirski, Colin Ian King,
Javier Martinez Canillas, Ken Xue, Mathias Krause, Rafael Wysocki,
Sinan Kaya).
- Update the device properties framework for better handling of
built-in properties, add support for built-in properties to
the platform bus type, update the MFD subsystem's handling
of device properties and add support for passing default
configuration data as device properties to the intel-lpss MFD
drivers, convert the designware I2C driver to use the unified
device properties API and add a fallback mechanism for using
default built-in properties if the platform firmware fails
to provide the properties as expected by drivers (Andy Shevchenko,
Mika Westerberg, Heikki Krogerus, Andrew Morton).
- Add new Device Tree bindings to the Operating Performance Points
(OPP) framework and update the exynos4412 DT binding accordingly,
introduce debugfs support for the OPP framework (Viresh Kumar,
Bartlomiej Zolnierkiewicz).
- Migrate the mt8173 cpufreq driver to the new OPP bindings
(Pi-Cheng Chen).

algorithm used by it to depend on the CPU ID of the processor it
is running on, make it use a special P-state selection algorithm
(with an IO wait time compensation tweak) on Atom CPUs based on
the Airmont and Silvermont cores so as to reduce their energy
consumption and improve intel_pstate documentation (Philippe
Longepe, Srinivas Pandruvada).
- Update the cpufreq-dt driver to support registering cooling
devices that use the (P * V^2 * f) dynamic power draw formula
where V is the voltage, f is the frequency and P is a constant

Pull oower management and ACPI updates from Rafael Wysocki:
"As far as the number of commits goes, ACPICA takes the lead this time,
followed by cpufreq and the device properties framework changes.
The most significant new feature is the debugfs-based interface to the
ACPICA's AML debugger added in the previous cycle and a new user space
tool for accessing it.
On the cpufreq front, the core is updated to handle governors more
efficiently, particularly on systems where a single cpufreq policy
object is shared between multiple CPUs, and there are quite a few
changes in drivers (intel_pstate, cpufreq-dt etc).
The device properties framework is updated to handle built-in (ie
included in the kernel itself) device properties better, among other
things by adding a fallback mechanism that will allow drivers to
provide default properties to be used in case the plaform firmware
doesn't provide the properties expected by them.
The Operating Performance Points (OPP) framework gets new DT bindings
and debugfs support.
A new cpufreq driver for ST platforms is added and the ACPI driver for
AMD SoCs will now support the APM X-Gene ACPI I2C device.
The rest is mostly fixes and cleanups all over.
Specifics:
- Add a debugfs-based interface for interacting with the ACPICA's AML
debugger introduced in the previous cycle and a new user space tool

Before updating time and alarm the driver must set appropriate mask in
UDR register. For that purpose the driver uses common register
configuration and a lot of exceptions per device in the code. The
exceptions are not obvious, for example except the change in the logic
sometimes the fields are swapped (WUDR and AUDR between S2MPS14 and
S2MPS15). This leads to quite complicated code.
Try to make it more obvious by:
1. Documenting the UDR masks for devices and operations.
2. Adding fields in register configuration structure for each operation
(read time, write time and alarm).
3. Splitting the configuration per S2MPS13, S2MPS14 and S2MPS15 thus
removing exceptions for them.

Usual mixed bag, but the big item perhaps in this series is the DMA buffer
support added by Lars-Peter Clausen. It's been in the works for a long time
and it will be interesting to see what hardware support shows up now that
this is available.
New core features + associate cleanup.
* Add generic DMA buffer infrastructure
* Add a DMAengine framework based buffer
Also associated minor changes.
- Set the device buffer watermark based on the minimum watermark for all
attached buffers rather than just the 'primary' one.
- iio_buffer_init - only set the watermark default if one hasn't already
been provided. This allows simple support for devices with a fixed
watermark.
- read only attribute for watermark on fixed watermark devices.
- add explicit buffer enable/disable callbacks to allow the buffer to
do more than trivial actions when it is being turned on and off.
* IIO_VAL_INT support in write_raw_get_fmt function.
New device support
* Freescale MMA7455/7456L accelerometers
* Memsic MXC6255XC accelerometer
* ST lis2dh12 accelerometer
* TI ADS8688 ADC
* TI Palamas (twl6035/7) gpadc
New driver features
* mma8452
- support either of the available interrupt pins to cope with the case
where board layout has lead to a particular one being connected.
Staging graduation
* Dummy driver
- this driver acts as both an example and a test device for those with
out hardware to develop userspace code against.
Cleanups and minor bits and bobs.
* treewide
- Sort out the ordering of iio_device_register/unregister vs runtime
pm function calls so that it's all nice and consistent and not race
prone.
- Check sscanf return values. None of the cases will actually happen as
the strings are supplied internally, but best to be consistent on this.
* ad7780
- switch over to the gpio descriptor interface and remove the now unused
platform data which gets rid of a header entirely.
* ad7793
- drop a pointless else statement.
* at91_adc
- Swap kmalloc_array in for a kmalloc doing the same job.
* dummy
- get rid of some commented out lines that snuck in during the move of
the driver.
* lm3533-als
- Print an error message on provision of an invalid resistance.
* mcp320x
- Add compatible strings with vendor prefix and deprecate those with
no vendor prefix.
* mxs-lradc
- Use BIT macro in various places rather than shifted ones.
* pa12203001
- Power off the chip if the registration fails.
* pulsedlight-lidar-lite
- add runtime PM support.
* xilinx XADC
- constify an iio_buffer_setup_ops structure.

and it will be interesting to see what hardware support shows up now that
this is available.
New core features + associate cleanup.
* Add generic DMA buffer infrastructure
* Add a DMAengine framework based buffer
Also associated minor changes.
- Set the device buffer watermark based on the minimum watermark for all
attached buffers rather than just the 'primary' one.
- iio_buffer_init - only set the watermark default if one hasn't already
been provided. This allows simple support for devices with a fixed
watermark.
- read only attribute for watermark on fixed watermark devices.
- add explicit buffer enable/disable callbacks to allow the buffer to
do more than trivial actions when it is being turned on and off.
* IIO_VAL_INT support in write_raw_get_fmt function.
New device support
* Freescale MMA7455/7456L accelerometers
* Memsic MXC6255XC accelerometer
* ST lis2dh12 accelerometer
* TI ADS8688 ADC
* TI Palamas (twl6035/7) gpadc
New driver features
* mma8452
- support either of the available interrupt pins to cope with the case
where board layout has lead to a particular one being connected.
Staging graduation
* Dummy driver
- this driver acts as both an example and a test device for those with
out hardware to develop userspace code against.
Cleanups and minor bits and bobs.
* treewide
- Sort out the ordering of iio_device_register/unregister vs runtime
pm function calls so that it's all nice and consistent and not race
prone.
- Check sscanf return values. None of the cases will actually happen as
the strings are supplied internally, but best to be consistent on this.
* ad7780
- switch over to the gpio descriptor interface and remove the now unused
platform data which gets rid of a header entirely.
* ad7793
- drop a pointless else statement.
* at91_adc
- Swap kmalloc_array in for a kmalloc doing the same job.
* dummy
- get rid of some commented out lines that snuck in during the move of
the driver.
* lm3533-als
- Print an error message on provision of an invalid resistance.
* mcp320x
- Add compatible strings with vendor prefix and deprecate those with
no vendor prefix.
* mxs-lradc
- Use BIT macro in various places rather than shifted ones.
* pa12203001
- Power off the chip if the registration fails.
* pulsedlight-lidar-lite
- add runtime PM support.
* xilinx XADC
- constify an iio_buffer_setup_ops structure.

RTC found in s2mps15 is almost same as one found on s2mps13
with few differences in RTC_UPDATE register fields, like:
1> Bit[4] and Bit[1] are reversed
- On s2mps13
WUDR -> bit[4], AUDR -> bit[1]
- On s2mps15
WUDR -> bit[1], AUDR -> bit[4]
2> In case of s2mps13, for alarm register, need to set both
WDUR and ADUR high, whereas for s2mps15 only set AUDR to high.

Here's the branch of chrome platform changes for v4.4. Some have been queued
up for the full 4.3 release cycle since I forgot to send them in for that
round (rebased early on to deal with fixes conflicts).
Most of these enable EC communication stuff -- Pixel 2015 support, enabling
building for ARM64 platforms, and a few fixes for memory leaks.
There's also a patch in here to allow reading/writing the verified boot
context, which depends on a sysfs patch acked by Greg.

This is quite a quiet release in terms of volume of patches but it
includes a couple of really nice core changes - the work Sascha has done
in particular is something I've wanted to get done for a long time but
just never got round to myself. Highlights include:
- Support from Sascha Hauer for setting the voltage of parent supplies
based on requests from their children. This is used both to allow
set_voltage() to work through a dumb switch and to improve the
efficiency of systems where DCDCs are used to supply LDOs by minimising
the voltage drop over the LDOs.
- Removal of regulator_list by Tomeu Vizoso, meaning we're not
duplicating the device list maintained by the driver core.
- Support for Wolfson/Cirrus WM8998 and WM1818.

The WRSTBI bit (disabled by default but enabled by bootloader), when
set, is responsible for resetting voltages to default values of
certain bucks on falling edge of Warm Reset Input pin from AP.
However on some boards (with S2MPS13) the pin is pulled down so any
suspend will effectively trigger the reset of bucks supplying the power
to the little and big cores. In the same time when resuming, these bucks
must provide voltage greater or equal to voltage before suspend to match
the frequency chosen by cpufreq. If voltage (default value of voltage
after reset) is lower than one set by cpufreq before suspend, then
system will hang during resuming.

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.

This adds a driver for the usb power_supply bits of the axp20x PMICs.
I initially started writing my own driver, before coming aware of
Bruno Prémont's excellent earlier RFC with a driver for this.
My driver was lacking CURRENT_MAX and VOLTAGE_MIN support Bruno's
drvier has, so I've copied the code for those from his driver.
Note that the AC-power-supply and battery charger bits will need separate
drivers. Each one needs its own devictree child-node so that other
devicetree nodes can reference the right power-supply, and thus each one
will get its own mfd-cell / platform_device and platform-driver.

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

"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"

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

Fix a missing DVC_RDY interrupt mask in struct regmap_irq definition.
The original submission of this driver did not contain all interrupt

da9063-irq.c
The solution is to add a DA9063_IRQ_DVC_RDY entry to enum da9063_irqs

mask bit in the static const struct regmap_irq da9063_irqs[] table.

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.

Merge tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Kevin Hilman:
"A relatively small setup of cleanups this time around, and similar to
last time the bulk of it is removal of legacy board support:
- OMAP: removal of legacy (non-DT) booting for several platforms
- i.MX: remove some legacy board files"

Pull input subsystem updates from Dmitry Torokhov:
"Thanks to Samuel Thibault input device (keyboard) LEDs are no longer
hardwired within the input core but use LED subsystem and so allow use
of different triggers; Hans de Goede did a large update for the ALPS

For the WM5102 there is a dependency in the core code on wm5102_patch()
which only exists when CONFIG_MFD_WM5102 is defined. To avoid having
to sprinkle #ifdefs around the code it is given an alternative empty
stub version when CONFIG_MFD_WM5102 is deselected

Later arizona silicon has the single/differential selector
in a different register, and IN1_MODE only selects between
analogue or digital. Prepare for this by splitting the
INx_MODE definition into two fields.

Allow the chip to completely power off if we enter runtime suspend and
there is no jack detection active. This is helpful for systems where
system suspend might remove the supplies to the CODEC, without informing
us. Note the powering off is done in runtime suspend rather than system
suspend, because we need to hold reset until the first time DCVDD is
powered anyway (which would be in runtime resume), and we might as well
save the extra power.
