From 153b4b9547965729120d427485e414855399acac Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Tue, 22 Oct 2013 22:05:09 -0700 Subject: [PATCH] drm/i915: Convert straggling MCHBAR registers All our registers which are written through the MCHBAR are defined descriptively as an offset to the MCHBAR. We had 3 outliers here. Convert these as well so all registers which are offsets are MCHBAR can be easily identified/found within the code. With this, convert DCLK to also follow this format.
