From 905b68223be18937159a29b354e6a332952ff952 Mon Sep 17 00:00:00 2001 From: Jerome Glisse Date: Wed, 9 Sep 2009 22:24:20 +0200 Subject: [PATCH] drm/radeon/kms: add R4XX mc register access helper. Atombios will use the mc register access helper and R4XX hw have a bigger mc range than R3XX so add R4XX specific mc register access helper.
