Subject: drm/amd/display: Enable ODM combine default policy
Git-commit: 9a23fcf79dc647627b3780284a156cc6e7bbd7c4
Patch-mainline: v6.0-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
[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.
