For DisplayPort use we need to set WIZ_CONFIG_LANECTL register's P_STANDARD_MODE bits to "mode 3". In the DisplayPort use also the P_ENABLE bits of the same register are set to P_ENABLE instead of P_ENABLE_FORCE, so that the DisplayPort driver can enable and disable the lane as needed. The DisplayPort mode is selected according to "cdns,phy-type"-properties found in link subnodes under the managed serdes (see "ti,sierra-phy-t0" and "ti,j721e-serdes-10g" devicetree bindings for details). All other values of "cdns,phy-type"-property but PHY_TYPE_DP will set P_STANDARD_MODE bits to 0 and P_ENABLE bits to force enable.

README
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.
