[Description] - When transitioning FRL / DP2 is not required, we will always request DTBCLK = 0Mhz, but PMFW returns the min freq - This causes us to make DTBCLK requests every time we call optimize after transitioning from FRL to non-FRL - If DTBCLK is not required, request the min instead (then we only need to make 1 extra request at boot time) - Also when programming PIPE_DTO_SRC_SEL, don't programming for DP first, just programming once for the required selection (programming DP on an HDMI connection then switching back causes corruption) Reviewed-by: Dillon Varone <Dillon.Varone@amd.com> Acked-by: Jasdeep Dhillon <jdhillon@amd.com> Signed-off-by: Alvin Lee <Alvin.Lee2@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
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.
