[Why] In init_hw() we call init_pipes() before enabling power gating. init_pipes() tries to power gate dsc but it may fail because required force-ons are not released yet. As a result with dsc config the following errors observed on resume: "REG_WAIT timeout 1us * 1000 tries - dcn20_dsc_pg_control" "REG_WAIT timeout 1us * 1000 tries - dcn20_dpp_pg_control" "REG_WAIT timeout 1us * 1000 tries - dcn20_hubp_pg_control" [How] Move enable_power_gating_plane() before init_pipes() in init_hw() Reviewed-by: Anthony Koo <Anthony.Koo@amd.com> Reviewed-by: Eric Yang <Eric.Yang2@amd.com> Acked-by: Alex Hung <alex.hung@amd.com> Signed-off-by: Roman Li <Roman.Li@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
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.
