From ce6e21370d5cacff3cd06c997af65316e7bba577 Mon Sep 17 00:00:00 2001 From: "C, Ramalingam" Date: Mon, 20 Nov 2017 09:53:47 +0530 Subject: [PATCH] i915/drrs/debugfs: psr status info addition 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].
