+Subject: [PATCH 3828/4256] drm/amd/display: Rebuild mapped resources after
+ pipe split
+
+[why]
+The issue is specific for linux, as on timings such as 8K@60
+or 4K@144 DSC should be working in combination with ODM Combine
+in order to ensure that we can run those timings. The validation
+for those timings was passing, but when pipe split was happening
+second pipe wasn't being programmed.
+
+[how]
+Rebuild mapped resources if we split stream for ODM.
