Make sure all the DP/HDMI/HDMI-FRL flags are programmed in all the modes the PLL is configured. Atm the DP mode flag is not programmed in case the PLL is configured for HDMI mode for instance. This is incorrect after HW reset, since the DP mode flag is asserted after reset, hence would need to be cleared for HDMI, but also incorrect because of the same reason after configuring the PLL to HDMI mode after it was used in DP mode (for instance on a DP++ connector). There is a similar issue with the HDMI-FRL flag, potentially remaining set when configuring the PLL in DP mode.

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.
