From: "C, Ramalingam" <ramalingam.c@xxxxxxxxx>
Existing debugfs entry i915_drrs_status is updated with whether PSR
is the cause for DRRS disabled state.
[v2]: Dropped the module parameter details as ctl moved from module
parameter to debugfs. [Rodrigo]
[v3]: Crtc ID information is dropped as there is no immediate usecase.
[Rodrigo].
