[why] during boot up or resume from s3, hw default value of domain_power_forceon is 1. when program domain_power_gate to 1 to power down hw block, hw will not change to power off due to domain_power_forceon = 1. [how] enable_power_gating_plane(true) should be executed to set domain_power_forceon to 0 before dsc_pg_control. dsc_pg_control is already called by dcn3x_init_hw--> init_pipes--> dsc_pg_control. no need be programmed with dcn3x_init_hw one more time. to trigger dchub, dsc block power state change, need program dc_ip_request_cntl to notify hw block.

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.
