From 2ef9bdfe64079c9d0b98dc89af3af52918b818a0 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Sun, 2 Dec 2012 14:02:51 +0100 Subject: [PATCH] drm/radeon: add W|RREG32_IDX for MM_INDEX|DATA based mmio accesss Just refactoring to make the next patche simpler. Now all indirect register access in the new modesetting driver should go through the r100_mm_(w|r)reg fucntions. RADEON_READ_MM from the old driver seems to be totally unused, so just kill it.
