From a8f78b582236a7e518ebcad8161b5599d3c92f5b Mon Sep 17 00:00:00 2001 From: Eugeni Dodonov Date: Thu, 28 Jun 2012 15:55:35 -0300 Subject: [PATCH] drm/i915: re-initialize DDI buffer translations after resume This is necessary for the modesetting to work correctly after a suspend-resume cycle. Without this, the pipes and clocks got the correct configuration, but the underlying DDI buffers configuration was lost.
