Kahola, Mika 1fa62e1b76 drm/i915/cnl: Enable wrpll computation for CNL
Enable wrpll computation for Cannonlake platform to support
pll's required for HDMI output. The patch contains the following features

- compute Cannonlake port clock programming
  dividers P, Q, and K.
- compute PLL parameters for Cannonlake. These parameters
  set the values on DPLL registers.
- find the register values to program wrpll for Cannonlake.
  The reference clock can be either 19.2MHz or 24MHz.

v2: rebase
v3: squash wrpll patches into one (Rodrigo)
v4: switch order of getting even dividers (Paulo)
    update divider register values for PDiv and KDiv (Paulo)
    update wrpll computation algorithm (Paulo)
v5: Remove ref clock division by 1000. (Rodrigo)
v6: Rodrigo rebasing on top of latest code.

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.
