[Why] Resuming from suspend, CEA blocks from EDID are not parsed and no video modes can support YUV420. When this happens, output bpc cannot go over 8-bit with 4K modes on HDMI. [How] In amdgpu_dm_update_connector_after_detect(), drm_add_edid_modes() is called after drm_connector_update_edid_property() to fully parse EDID and update display info.

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.
