From 36b5f425dd560d37f5633cf317818377c1db70de Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 16 Oct 2014 21:27:30 +0300 Subject: [PATCH] drm/i915: Store power sequencer delays in intel_dp MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The power seqeuncer delays are fixed for a given panel, so we can keep them around once computed. Not that on VLV/CHV we still re-compute them every time we initialize the power seqeuncer registers, but that will change soon enough.
