Subject: [PATCH 08/13] drm/amd/display: DCEFCLK DS on CLK init
Date: Fri, 14 Jan 2022 09:36:52 +0800	[thread overview]
Message-ID: <20220114013657.3119627-9-Wayne.Lin@amd.com> (raw)
In-Reply-To: <20220114013657.3119627-1-Wayne.Lin@amd.com>

From: Chris Park <Chris.Park@amd.com>

[Why]
On HG APU + dGPU scenario with no display to dGPU,
DS stays disabled due to no display present.
This problem can be worked around by DAL calling
DCEFCLK DS message to SMU on clk init.

[How]
Call DCEFCLK DS message to SMU on clk init.
