From c20cd31252554b927ae1cce1c71ae8a769b1bd74 Mon Sep 17 00:00:00 2001 From: Paulo Zanoni Date: Tue, 19 Feb 2013 16:21:45 -0300 Subject: [PATCH] drm/i915: unify the definitions of the HDMI/SDVO register Since they're all the same register, leave all the #defines at the same place, organized by Gen and also specify which bits are used by only a specific port or encoding. Also remove a few unused duplicates and adjust indentation.
