[Why] To process SET_CONFIG transactions with DMUB using inbox1 and outbox1 mail boxes. [How] 1) Added inbox1 DPIA command subtype DMUB_CMD__DPIA_SET_CONFIG_ACCESS to issue SET_CONFIG command to DMUB in dc_process_dmub_set_config_async(). DMUB processes the command with DPIA sends reply back immediately or in an outbox1 message triggering an outbox1 interrupt to driver. 2) DMUB posts SET_CONFIG reply as an Outbox1 message of type DMUB_OUT_CMD__SET_CONFIG_REPLY. 3) The dmub async to sync mechanism for AUX is modified to accommodate SET_CONFIG commands for both command issue and reply code paths.

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.
