Subject: [PATCH 12/27] drm/amd/display: wait for outstanding hw updates
Date: Tue, 25 Feb 2025 14:35:55 +0800 [thread overview]
Message-ID: <20250225063610.631461-13-Wayne.Lin@amd.com> (raw)
In-Reply-To: <20250225063610.631461-1-Wayne.Lin@amd.com>
From: Ausef Yousof <Ausef.Yousof@amd.com>
[why&how]
seeing display corruption as a result of not waiting for certain values
to latch and attempting otg locking/programming before waiting for them,
there is code in place for this but dcn35 does not initialize these
functions.
