Subject: [PATCH 01/14] drm/amd/display: Secondary display goes blank on Non DCN31
Date: Fri, 12 Nov 2021 08:54:25 +0800 [thread overview]
Message-ID: <20211112005438.5505-2-Wayne.Lin@amd.com> (raw)
In-Reply-To: <20211112005438.5505-1-Wayne.Lin@amd.com>
From: Ahmad Othman <Ahmad.Othman@amd.com>
[Why]
Due to integration issues with branch merging,
a regression happened that prevented secondary
displays from lighting up or enabling certain features
[How]
Separated the new logic to be for DCN31 only and retained
pre DCN31 logic for all other ASICs
