drm/radeon/kms: fix up gpio i2c mask bits for r4xx 2011-12-09T16:52:23+00:00 Alex Deucher alexander.deucher@amd.com 2011-11-14T19:32:01+00:00 ff17063daf7bcf76ee1b1cc59e20ae725affc555 commit 6c47e5c23aa2a7c54ad7ac13af4bd56cd9e703bf upstream.

drm/i915: fix CB tuning check for ILK+ 2011-12-09T16:52:22+00:00 Jesse Barnes jbarnes@virtuousgeek.org 2011-07-28T21:50:30+00:00 ed3035ddf88840f6e8355281e74b2b0bb9c93da0 commit cb0e093162d7b6589c2217a00e2abfef686b32d6 upstream. CB tuning is needed to handle potential process variations that might cause clock jitter for certain PLL settings. However, we were setting it incorrectly since we were using the wrong M value as a check (M1 when we needed to use the whole M value). Fix it up, making my HDMI attached display a little prettier (used to have occasional dots crawl across the display).
