Subject: [PATCH 03/24] drm/amd/display: Don't enable AFMT for DP audio stream
Date: Fri, 24 Sep 2021 15:09:13 -0400	[thread overview]
Message-ID: <20210924190934.1193379-4-Anson.Jacob@amd.com> (raw)
In-Reply-To: <20210924190934.1193379-1-Anson.Jacob@amd.com>

From: Michael Strauss <michael.strauss@amd.com>

[WHY]
AFMT is unused for DP audio, so powering it on for DP is unnecessary.

[HOW]
APG block should be powered down instead, however HW defaults to shutdown
state when not enabled so no further work is required.
