+Subject: [PATCH 5422/5725] drm/amd/dc: Trigger set power state task when
+ display configuration changes
+
+Revert "drm/amd/display: Remove call to amdgpu_pm_compute_clocks"
+
+This reverts commit dcd473770e86517543691bdb227103d6c781cd0a.
+
+when display configuration changes, dc need to update the changes
+to powerplay, also need to trigger a power state task.
+amdgpu_pm_compute_clocks is the interface to set power state task
+either dpm enabled or powerplay enabled
