backlight_led is the dimmable backlight for the rubber border on the case. It is also used to highlight the power- and some other buttons. MX6QDL_PAD_SD4_DAT1__PWM3_OUT is also assigned as output for pwm3. Since we need pwm3 for the backlight, we're forced to disable user space hardware revision detection. The bootloader will have to supply this information (i.e. through device tree).

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.
