Mitul Golani 7fbad577c8 drm/i915/display: WA for Re-initialize dispcnlunitt1 xosc clock
The dispcnlunit1_cp_xosc_clk should be de-asserted in display off
and only asserted in display on. As part of this workaround, Display
driver shall execute set-reset sequence at the end of the initialize
sequence to ensure clk does not remain active in display OFF.

--v2:
- Rebase.
--v3:
- Correct HSD number in commit message.
--v4:
- Reformat commit message.
- Use intel_de_rmw instead of intel_de_write
--v5:
- Build Fixes.

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 reStructuredText 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.
