From 6fa228ba96f8c35de2f1ec9eabaa45d3865b1d0c Mon Sep 17 00:00:00 2001 From: James Ausmus Date: Thu, 12 Oct 2017 14:30:36 -0700 Subject: [PATCH] drm/i915: Fix DP_AUX_CH_CTL_TIME_OUT naming Rename DP_AUX_CH_CTL_TIME_OUT_1600us to DP_AUX_CH_CTL_TIME_OUT_MAX, as the meaning of the (3 << 26) value varies per platform, but it's always the maximum timeout for that platform. Pre-CNL it means 1600us, and for CNL it means 3200us. v2: -Split in to two patches (Rodrigo) Cc: Rodrigo Vivi Signed-off-by: James Ausmus Reviewed-by: Rodrigo Vivi Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/20171012213037.4245-1-james.ausmus@intel.com --- drivers/gpu/drm/i915/i915_reg.h | 2 +- drivers/gpu/drm/i915/intel_dp.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_reg.h b/drivers/gpu/drm/i915/i915_reg.h index d2d0a83c09b6d..5f99d4d6291b9 100644 --- a/drivers/gpu/drm/i915/i915_reg.h +++ b/drivers/gpu/drm/i915/i915_reg.h @@ -5242,7 +5242,7 @@ enum { #define DP_AUX_CH_CTL_TIME_OUT_400us (0 << 26) #define DP_AUX_CH_CTL_TIME_OUT_600us (1 << 26) #define DP_AUX_CH_CTL_TIME_OUT_800us (2 << 26) -#define DP_AUX_CH_CTL_TIME_OUT_1600us (3 << 26) +#define DP_AUX_CH_CTL_TIME_OUT_MAX (3 << 26) /* Varies per platform */ #define DP_AUX_CH_CTL_TIME_OUT_MASK (3 << 26) #define DP_AUX_CH_CTL_RECEIVE_ERROR (1 << 25) #define DP_AUX_CH_CTL_MESSAGE_SIZE_MASK (0x1f << 20) diff --git a/drivers/gpu/drm/i915/intel_dp.c b/drivers/gpu/drm/i915/intel_dp.c index 753404280a196..3f0d37fa833f2 100644 --- a/drivers/gpu/drm/i915/intel_dp.c +++ b/drivers/gpu/drm/i915/intel_dp.c @@ -1032,7 +1032,7 @@ static uint32_t skl_get_aux_send_ctl(struct intel_dp *intel_dp, DP_AUX_CH_CTL_DONE | (has_aux_irq ?
