[Why] Certain small HBlank timings may not have a large enough HBlank to support audio when low bpp DSC is enabled. HBlank expansion by the source can solve this problem, but requires the branch/sink to support HBlank reduction. [How] Update DPMS sequence to call DM to perform DPCD write to enable HBlank reduction on the branch/sink. Add stub in dm_helpers to be implemented later.

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.
