[Why] with eDP + DP, each display use one pipe. after DP unplugged, eDP switch from one pipe to two pipes -- pipe split. dpp1_cm_set_regamma_pwl will be executed too. The duration from switch single pipe to dual pipes is a little long which could let eDP enter PSR mode. upon two pipes for eDP are setup, eDP PHY is disabled. front pipe is not really running to fetch data from frame buffer. i.e., dchubp is not in normal working status. execution of hubbub1_wm_change_req_wa may cause p-state warning. [How] disable eDP PSR before dc_commit_state. psr is disabled when execute hubbub1_wm_change_req_wa.

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.
