Subject: [PATCH 13/27] drm/amd/display: Release DSC before acquiring
Date: Fri, 29 Jan 2021 16:27:38 -0500	[thread overview]
Message-ID: <20210129212752.38865-14-Anson.Jacob@amd.com> (raw)
In-Reply-To: <20210129212752.38865-1-Anson.Jacob@amd.com>

From: Mikita Lipski <mikita.lipski@amd.com>

[why]
Need to unassign DSC from pipes that are not using it
so other pipes can acquire it. That is needed for
asic's that have unmatching number of DSC engines from
the number of pipes.

[how]
Before acquiring dsc to stream resources, first remove it.
