On the Android yb1-x90f/l models there is not ACPI method to control the keyboard backlight brightness. Instead the second PWM controller is exposed directly to the OS there. Add support for controlling keyboard backlight brightness on the Android model by using the PWM subsystem to directly control the PWM. The Android model also requires explicitly turning the backlight off on suspend, which on the Windows model was done automatically.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
