5d4be5f2b1 platform/x86: dell-rbtn: Improve explanation about DELLABC6
According to Mario at Dell, the DELLABC6 device should not be used on a
Linux system. It also conflicts with Intel-HID and its interactions with
Network Manager. Document that we are aware of the device, but that we
are intentionally ignoring it.

d659d11ad3 platform/x86: fujitsu-laptop: use device-specific data in remaining module code
To avoid using module-wide data in remaining module code, employ
acpi_driver_data() and dev_get_drvdata() to fetch device-specific data
to work on in each function.  This makes the input local variables in
hotkey-related callbacks and the module-wide struct fujitsu_laptop
redundant, so remove them.  Adjust whitespace to make checkpatch happy.

a823f8e757 platform/x86: fujitsu-laptop: use device-specific data in LED-related code
In order to perform their duties, all LED callbacks need a pointer to
the struct acpi_device representing the FUJ02E3 ACPI device.  To limit
the use of the module-wide pointer, the same pointer should be extracted
from data that gets passed to LED callbacks as arguments.  However, LED
core does not currently support supplying driver-specific pointers to
struct led_classdev callbacks, so the latter have to be implemented a
bit differently than backlight device callbacks and platform device
attribute callbacks.  As the FUJ02E3 ACPI device is the parent device of
all LED class devices registered by fujitsu-laptop, struct acpi_device
representing the former can be extracted by following the parent link
present inside the struct device belonging to the struct led_classdev
passed as an argument to each LED callback.

To get rid of module-wide structures defining LED class devices,
allocate them dynamically using devm_kzalloc() and initialize them in
acpi_fujitsu_laptop_leds_register().

84631e0c8b platform/x86: fujitsu-laptop: explicitly pass ACPI device to call_fext_func()
Prepare for not using module-wide data in call_fext_func() by explicitly
passing it a pointer to struct acpi_device while still using a
module-wide pointer in each call.

Doing this enables call_fext_func() to fetch the ACPI handle from its
argument, making the acpi_handle field of struct fujitsu_laptop useless,
so remove that field.  While we are at it, the dev field of the same
structure is assigned in acpi_fujitsu_laptop_add() but not used for
anything, so remove it as well.

ca0d9eab0f platform/x86: fujitsu-laptop: track the last instantiated FUJ02E3 ACPI device
fujitsu-laptop registers two ACPI drivers: one for ACPI device FUJ02B1
enabling backlight control and another for ACPI device FUJ02E3 which
handles various other stuff (hotkeys, LEDs, etc.)  In a perfect world,
private data used by each of these drivers would be neatly encapsulated
in a structure specific to a given driver instance.  Sadly, firmware
present on some Fujitsu laptops makes that impossible by exposing
backlight power control (which is what the FUJ02B1 ACPI device should
take care of) through the FUJ02E3 ACPI device.  This means the backlight
driver needs a way to access an ACPI device it is not bound to.  When
the backlight driver is extracted into a separate module, it will not be
able to rely on a module-wide variable any more and such access will
happen through an API exposed by fujitsu-laptop.

For all known firmwares out in the wild, it seems that whenever the
FUJ02B1 ACPI device is present, it is always accompanied by a single
instance of the FUJ02E3 ACPI device.  We could independently grab an
ACPI handle to the FUJ02E3 ACPI device from the backlight driver, but
that would require using a hardcoded absolute path to that ACPI device,
which is subject to change.  It is easier to simply store a module-wide
pointer to the last (most likely only) FUJ02E3 ACPI device found, make
the aforementioned API use it and cover our bases by warning the user if
firmware exposes multiple FUJ02E3 ACPI devices.

Introducing this pointer in advance allows us to get rid of the
acpi_handle field of struct fujitsu_bl and also enables a bit more
step-by-step migration to a device-specific implementation of
call_fext_func().

13bb0fd551 platform/x86: peaq-wmi: Add new peaq-wmi driver
PEAQ is a new European OEM, I've bought one of their 2-in-1 x86 devices,
which is actually quite a nice device. Under Windows it has Dolby
software for "better" sound and you can select different equalizer
presets using a special button.

This WMI interface for this button is not really nice, as it does not do
notifies (it really does not I triple checked), but since I had already
figured out the entire WMI interface for this I decided to go the full
mile anyway and implement a WMI based input driver for this using
input_polldev since, well, we need to poll.

This commit adds support for this button making it report KEY_SOUND
input events. KEY_SOUND is already used in various places to switch
sound into theatre mode and things like that so it seems appropriate
here.

Note: The ideapad-laptop driver does not provide a SW_TABLET_MODE either.

 "This is the bulk of GPIO changes for the v4.12 kernel cycle.

  Core changes:

   - Return NULL from gpiod_get_optional() when GPIOLIB is disabled.
     This was a much discussed change. It affects use cases where people
     write drivers that might or might not be using GPIO resources. I
     have decided that this is the lesser evil right now.

   - Make gpiod_count() behave consistently across different hardware
     descriptions.

   - Fix the syntax around open drain/open source to not infer active
     high/low semantics.

  New drivers:

   - A new single-register fixed-direction framework driver for hardware
     that have lines controlled by a single register that just work in
     one direction (out or in), including IRQ support.

   - Support the Fintek F71889A GPIO SuperIO controller.

   - Support the National NI 169445 MMIO GPIO.

   - Support for the X-Gene derivative of the DWC GPIO controller

   - Support for the Rohm BD9571MWV-M PMIC GPIO controller.

   - Refactor the Gemini GPIO driver to a generic Faraday FTGPIO driver
     and replace both the Gemini and the Moxa ART custom drivers with
     this driver.

  Driver improvements:

   - A whole slew of drivers have their spinlocks chaned to raw
     spinlocks as they provide irqchips, and thus we are progressing on
     realtime compliance.

   - Use devm_irq_alloc_descs() in a slew of drivers, getting managed
     resources.

   - Support for the embedded PWM controller inside the MVEBU driver.

   - Debounce, open source and open drain support for the Aspeed driver.

f9ac89f5ad platform/x86: acer-wmi: setup accelerometer when ACPI device was found
The 98d610c373 patch was introduced since v4.11-rc1 that it causes
that the accelerometer input device will not be created on workable
machines because the HID string comparing logic is wrong.

And, the patch doesn't prevent that the accelerometer input device
be created on the machines that have no BST0001. That's because
the acpi_get_devices() returns success even it didn't find any
match device.

This patch fixed the HID string comparing logic of BST0001 device.
And, it also makes sure that the acpi_get_devices() returns
acpi_handle for BST0001.

Fixes: 98d610c373 ("acer-wmi: setup accelerometer when machine has appropriate notify event")

iTCO_wdt driver need access to PMC_CFG GCR register to modify the
noreboot setting. Currently, this is done by passing PMC_CFG reg
address as memory resource to watchdog driver and allowing it directly
modify the PMC_CFG register. But currently PMC driver also has
requirement to memory map the entire GCR register space in this driver.
This causes mem request failure in watchdog driver. So this patch fixes
this issue by adding API to update noreboot flag and passes them
to watchdog driver via platform data.

to acces GCR registers. These API's can be used for this
purpose.

e6749c89b4 platform/x86: intel_pmc_ipc: fix gcr offset
According to Broxton APL spec, PMC MIMO resources for Global Control
Registers(GCR) are located at 4K(0x1000) offset from IPC base address.
In this driver, PLAT_RESOURCE_GCR_OFFSET macro defines the offset of GCR
region base address from IPC base address and its current value of
0x1008 is incorrect because it points to location for PMC_CFG register
and not the GCR base address itself.

GCR Base = IPC1 Base + 0x1000.

This patch fixes this offset issue.

9216e0dcb5 platform/x86: dell-laptop: Add keyboard backlight timeout AC settings
When changing keyboard backlight state on new Dell laptops, firmware
expects a new timeout AC value filled in Set New State SMBIOS call.

Without it any change of keyboard backlight state on new Dell laptops
fails. And user can see following error message in dmesg:

  dell_laptop: Setting old previous keyboard state failed
  leds dell::kbd_backlight: Setting an LED's brightness failed (-6)

This patch adds support for retrieving current timeout AC values and also
updating them. Current timeout value in sysfs is displayed based on current
AC status, like current display brightness value.

Detection if Dell laptop supports or not new timeout AC settings is done by
checking existence of Keyboard Backlight with AC SMBIOS token (0x0451).

b5238b4185 mfd: intel_soc_pmic: Fix a mess with compilation units
Crystal Cove and Whiskey Cove are two different PMICs which are
installed on Intel Atom SoC based platforms.

Moreover there are two independent drivers that by some reason were
supposed (*) to get into one kernel module.

Fix the mess by clarifying Kconfig option for Crystal Cove and split
Whiskey Cove out of it.

(*) It looks like the configuration was never tested with
    INTEL_SOC_PMIC=n. The line in Makefile is actually wrong.

f563dab417 goldfish_pipe: fix build warning about using too much stack.
The new goldfish_pipe code used too much stack space in the
transfer_max_buffers() call.  As the function is serialized with a lock,
let's make the buffer static to not use the stack for the large buffer.

726ea1a8ea goldfish_pipe: An implementation of more parallel pipe
This is a driver code for a redesigned android pipe.
Currently it works for x86 and x64 emulators with the following
performance results:
  ADB push to /dev/null,
  Ubuntu,
  400 MB file,
  times are for (1 / 10 / 100) parallel adb commands
x86 adb push: (4.4s / 11.5s / 2m10s) -> (2.8s / 6s / 51s)
x64 adb push: (7s / 15s / (too long, 6m+) -> (2.7s / 6.2s / 52s)

ADB pull and push to /data/ have the same %% of speedup
More importantly, I don't see any signs of slowdowns when
run in parallel with Antutu benchmark, so it is definitely
making much better job at multithreading.
