b139557f41
In preparation for adding the HDMI TX v2 driver, and to allow
a future modernization of the HDMI v1 one, perform changes
that enable the usage of the HDMI Helpers provided by DRM.
Check if the HDMI driver provides the function pointers to
hdmi_{clear,write}_infoframe used by the HDMI Helper API and,
if present, add DRM_BRIDGE_OP_HDMI to the drm_bridge ops,
enabling the drm API to register the bridge as HDMI and to use
the HDMI Helper functions.
If the hdmi_{write,clear}_infoframe pointers are not assigned,
vendor and product strings and HDMI helpers will not be used,
hence this commit brings no functional changes to drivers that
have not been refactored to use the new helpers.
This also means that, in the current state, there is effectively
no functional change to mtk_hdmi and its other components.

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.
