Subject: [PATCH 5.15 57/73] drm/amd/display: Changed pipe split policy to allow for multi-display pipe split
Date: Mon, 3 Jan 2022 15:24:18 +0100 [thread overview]
Message-ID: <20220103142058.762278116@linuxfoundation.org> (raw)
In-Reply-To: <20220103142056.911344037@linuxfoundation.org>
From: Angus Wang <angus.wang@amd.com>
commit ee2698cf79cc759a397c61086c758d4cc85938bf upstream.
[WHY]
Current implementation of pipe split policy prevents pipe split with
multiple displays connected, which caused the MCLK speed to be stuck at
max
[HOW]
Changed the pipe split policies so that pipe split is allowed for
multi-display configurations
