drm/radeon/kms: fix DP setup on TRAVIS bridges

2011-12-21T20:58:32+00:00

commit cf2aff6eff251b6fbdaf8c253e65ff7c693de8cd upstream. Supposedly both NUTMEG and TRAVIS should use the same panel mode, but switching the panel mode for TRAVIS gets things working.

drm/radeon/kms: rework DP bridge checks

2011-12-21T20:58:32+00:00

commit 1d33e1fc8dcce667a70387b666a8b6f60153d90f upstream. Return the encoder id rather than a boolean. This is needed for differentiate between multiple DP bridge chips. Signed-off-by: Alex Deucher Signed-off-by: Dave Airlie Signed-off-by: Greg Kroah-Hartman

drm/radeon/kms: cleanup atombios_adjust_pll()

2011-12-21T20:58:32+00:00

commit b4f15f808b9a79b6ad9032fa5f6d8b88e1e1bf11 upstream. The logic was messy and hard to follow. Signed-off-by: Alex Deucher Signed-off-by: Dave Airlie Signed-off-by: Greg Kroah-Hartman

drm/radeon/kms: add some loop timeouts in pageflip code

2011-12-09T16:54:32+00:00

commit f64964796dedca340608fb1075ab6baad5625851 upstream. Avoid infinite loops waiting for surface updates if a GPU reset happens while waiting for a page flip.

drm/radeon/kms: fix up gpio i2c mask bits for r4xx

2011-12-09T16:54:09+00:00

commit 6c47e5c23aa2a7c54ad7ac13af4bd56cd9e703bf upstream. Fixes i2c test failures when i2c_algo_bit.bit_test=1. The hw doesn't actually require a mask, so just set it to the default mask bits for r1xx-r4xx radeon ddc.

drm/i915: Fix inconsistent backlight level during disabled

2011-12-09T16:54:08+00:00

commit 04b38670cf46c096705f24e92a8747d1ab89e53c upstream. When the brightness property is inquired while the backlight is disabled, the driver returns a wrong value (zero) because it probes the value after the backlight was turned off. This caused a black screen even after the backlight is enabled again. It should return the internal backlight_level instead, so that it won't be influenced by the backlight-enable state.

drm/i915: Turn on another required clock gating bit on gen6.

commit 9ca1d10d748e56964de95e3ed80211b192f56cf4 upstream. Unlike the previous one, I don't have known testcases it fixes. I'd rather not go through the same debug cycle on whatever testcases those might be. Signed-off-by: Eric Anholt Signed-off-by: Keith Packard Signed-off-by: Greg Kroah-Hartman

drm/i915: Turn on a required 3D clock gating bit on Sandybridge.

drm/radeon/kms: fix up gpio i2c mask bits for r4xx for real

2011-12-09T16:54:07+00:00

commit d724502a9d7a46f4a56a1663b1f50d2dc9d1ef40 upstream. Fixes i2c test failures when i2c_algo_bit.bit_test=1. The hw doesn't actually require a mask, so just set it to the default mask bits for r1xx-r4xx radeon ddc. I missed this part the first time through.
