Subject: [Intel-gfx] [PATCH 11/11] drm/i915/display: Add HW state readout for VRR
Date: Thu, 22 Oct 2020 15:27:09 -0700	[thread overview]
Message-ID: <20201022222709.29386-12-manasi.d.navare@intel.com> (raw)
In-Reply-To: <20201022222709.29386-1-manasi.d.navare@intel.com>

This functions gets the VRR config from the VRR registers
to match the crtc state variables for VRR.
