This patch introduce a drm property hdmi_output_depth to get/set HDMI color depth, the possible value could be - Automatic This indicates prefer highest color depth, it is 30bit on rockcip platform. - 24bit - 30bit The default value of property is 24bit. The max_tmds_clock is 0 on some display device, we think it's max_tmds_clock is 340MHz. If tmdsclock > max_tmds_clock, real output color depth fallback to 24bit.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
