From 9a23fcf79dc647627b3780284a156cc6e7bbd7c4 Mon Sep 17 00:00:00 2001 From: Aurabindo Pillai Date: Thu, 7 Jul 2022 14:28:03 -0400 Subject: [PATCH] drm/amd/display: Enable ODM combine default policy [Why&How] Output Data Mapping is a power saving feature that allows us to run at reduced DPP and DISP clocks compared to what could be achieved with a single pipe. Set the default policy for single display use case to use 2 to 1 ODM combine. The options are queried by DC and appropriate register programming sequence is initiated to enable this feature.
