Split out BXT and CNP's setup_backlight(),enable_backlight(),
disable_backlight() and hz_to_pwm() into
two separate functions instead of reusing BXT function.
Reuse set_backlight() and get_backlight() since they have
no reference to the utility pin.
v2: Reuse BXT functions with controller 0 instead of
redefining it. (Jani).
Use dev_priv->rawclk_freq instead of getting the value
from SFUSE_STRAP.
v3: Avoid setup backligh controller along with hooks and
fully reuse hooks setup as suggested by Jani.
v4: Clean up commit message.
v5: Implement per PCH instead per platform.
v6: Introduce a new function for CNP.(Jani and Ville)
v7: Squash the all CNP Backlight support patches into a
single patch. (Jani)
v8: Correct indentation, remove unneeded blank lines and
correct mail address (Jani).
v9: Remove unused enum pipe. (by CI)
v10: Remove comment mentioning SFUSE_STRAP in a part of
the code that we don't use it. (Jani)
Make controller = 0 since current CNP has only one
controller and put a comment mentioning why we
reuse the BXT definitions and are keeping the
controller = 0. (DK)
v11: Remove spurious line. (DK)

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
