Subject: [PATCH 06/19] drm/amd/display: update dio for two pixel per container case
Date: Sat, 18 Mar 2023 03:56:02 -0400	[thread overview]
Message-ID: <20230318075615.2630-7-qingqing.zhuo@amd.com> (raw)
In-Reply-To: <20230318075615.2630-1-qingqing.zhuo@amd.com>

From: Charlene Liu <Charlene.Liu@amd.com>

[why]
Processing rate of the DP encoder, must be programmed to be the same as
DIG_FIFO_OUTPUT_ PROCESSING_MODE in DP mode
0: 1 pixel per cycle
1: 2 pixel per cycle
