Subject: [PATCH 1/3] drm/amdgpu/powerplay/smu7: enable mclk switching if monitors are synced
Date: Thu, 22 Aug 2019 10:36:43 -0500	[thread overview]
Message-ID: <20190822153645.3296-2-alexander.deucher@amd.com> (raw)
In-Reply-To: <20190822153645.3296-1-alexander.deucher-5C7GfCeVMHo@public.gmane.org>

If DC has synced the displays, we can enable mclk switching to
save power.
