If anyone has any objections, please let me know. ------------------ From: Imre Deak commit 77fa4cbd5fa389e28419bbe8ac491b5fdd54840d upstream. Fix the typo introduced in commit 1a2eb4604b85c5efb343da8a4dcf41288fcfca85 Author: Keith Packard Date: Wed Nov 16 16:26:07 2011 -0800 drm/i915: Hook up Ivybridge eDP This fixes eDP link-training failures and cases where all voltage swing /pre-emphasis levels were tried and failed during clock recovery and - as a fallback - we go on to do channel equalization with the last voltage swing/pre-emphasis level which will succeed. Both issues can lead to a blank screen. v2: - improve commit message Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=64880 Tested-by: Jeremy Moles Signed-off-by: Imre Deak Reviewed-by: Paulo Zanoni Signed-off-by: Daniel Vetter Signed-off-by: Luis Henriques --- drivers/gpu/drm/i915/i915_reg.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/i915_reg.h b/drivers/gpu/drm/i915/i915_reg.h index 70bfc0f..e275ef6 100644 --- a/drivers/gpu/drm/i915/i915_reg.h +++ b/drivers/gpu/drm/i915/i915_reg.h @@ -3991,7 +3991,7 @@ #define EDP_LINK_TRAIN_600MV_0DB_IVB (0x30 <<22) #define EDP_LINK_TRAIN_600MV_3_5DB_IVB (0x36 <<22) #define EDP_LINK_TRAIN_800MV_0DB_IVB (0x38 <<22) -#define EDP_LINK_TRAIN_800MV_3_5DB_IVB (0x33 <<22) +#define EDP_LINK_TRAIN_800MV_3_5DB_IVB (0x3e <<22) /* legacy values */ #define EDP_LINK_TRAIN_500MV_0DB_IVB (0x00 <<22) -- 1.8.3.2 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
