First of all, since the PSR feature can help to reduce the power
consumption, the Source device, which can support PSR function,
should enable PSR if the PSR capability of Sink device is detected
rather than depending on the user to add 'support-psr' DTS property
manually.
Different platforms that use the same Analogix DP bridge driver may
have different methods for parsing the PSR capability. Therefore, add
a new flag &analogix_dp_plat_data.disable_psr to disable PSR forcely,
which set in the platform side, should be more reasonable.
If the user truly does not want to enable PSR function or the Panel
has something wrong with it, the property 'rockchip,disable-psr' will
be helpful.

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.
