Merge tag 'platform-drivers-x86-v4.20-1' of git://git.infradead.org/linux-platform-drivers-x86 

Pull x86 platform driver updates from Darren Hart:

 - Move the Dell dcdbas and dell_rbu drivers into platform/drivers/x86
   as they are closely coupled with other drivers in this location.

 - Improve _init* usage for acerhdf and fix some usage issues with
   messages and module parameters.

 - Simplify asus-wmi by calling ACPI/WMI methods directly, eliminating
   workqueue overhead, eliminate double reporting of keyboard backlight.

 - Fix wake from USB failure on Bay Trail devices (intel_int0002_vgpio).

 - Notify intel_telemetry users when IPC1 device is not enabled.

 - Update various drivers with new laptop model IDs.

 - Update several intel drivers to use SPDX identifers and order headers
   alphabetically.

LG Gram laptop extra features

=============================



By Matan Ziv-Av <matan@svgalib.org>





Hotkeys

-------



The following FN keys are ignored by the kernel without this driver:

- FN-F1 (LG control panel)   - Generates F15

- FN-F5 (Touchpad toggle)    - Generates F13

- FN-F6 (Airplane mode)      - Generates RFKILL

- FN-F8 (Keyboard backlight) - Generates F16.

  This key also changes keyboard backlight mode.

- FN-F9 (Reader mode)        - Generates F14



The rest of the FN key work without a need for a special driver.





Reader mode

-----------



Writing 0/1 to /sys/devices/platform/lg-laptop/reader_mode disables/enables

reader mode. In this mode the screen colors change (blue color reduced),

and the reader mode indicator LED (on F9 key) turns on.





FN Lock

-------



Writing 0/1 to /sys/devices/platform/lg-laptop/fn_lock disables/enables

FN lock.





Battery care limit

------------------



Writing 80/100 to /sys/devices/platform/lg-laptop/battery_care_limit

sets the maximum capacity to charge the battery. Limiting the charge

reduces battery capacity loss over time.



This value is reset to 100 when the kernel boots.





Fan mode

--------



Writing 1/0 to /sys/devices/platform/lg-laptop/fan_mode disables/enables

the fan silent mode.





USB charge

----------



Writing 0/1 to /sys/devices/platform/lg-laptop/usb_charge disables/enables

charging another device from the USB port while the device is turned off.



This value is reset to 0 when the kernel boots.





LEDs

~~~~



The are two LED devices supported by the driver:



Keyboard backlight

------------------



A led device named kbd_led controls the keyboard backlight. There are three

lighting level: off (0), low (127) and high (255).



The keyboard backlight is also controlled by the key combination FN-F8

which cycles through those levels.





Touchpad indicator LED

----------------------



On the F5 key. Controlled by led device names tpad_led.
