Subject: [PATCH 4/6] drm/i915/dp: Restore PPS HW state from the encoder resume hook
Date: Tue,  9 Aug 2016 14:34:10 +0300	[thread overview]
Message-ID: <1470742452-5240-5-git-send-email-imre.deak@intel.com> (raw)
In-Reply-To: <1470742452-5240-1-git-send-email-imre.deak@intel.com>

Similarly to the previous patch, initialize the PPS from the DP
encoder's resume hook. Note that as opposed to LVDS we can't do this
during encoder enabling, since we need the PPS for DP detection as well.
