We want userspace to represent the human perceived brightness. Since the led drivers and the leds themselves don't have a linear response to the value we give them in terms of perceived brightness, we'll bake the curve into the dts. The panel also doesn't have a good response under 5%, so we'll avoid sending it anything lower than that. Note: Ideally this patch should be coupled with the driver change from "backlight: pwm_bl: Fix interpolation", but it can work without it, without looking too ugly.

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.
