Jerome Brunet fa2d2e2d8e drm/meson: dw-hdmi: add bandgap setting for g12 
[ Upstream commit 0800103312 ]

When no mode is set, the utility pin appears to be grounded. No signal
is getting through.

This is problematic because ARC and eARC use this line and may do so even
if no display mode is set.

This change enable the bandgap setting on g12 chip, which fix the problem
with the utility pin. This is done by restoring init values on PHY init and
disable.

README 

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.
