From: Sonika Jindal <sonika.jin...@intel.com> Renaming the HSW-specific macros for ddi buffer translation slot to denote the slot and not the vswing/pre-emph values as they are platform-dependent.
This patch is based on top of the patch series for renaming the DP training vswing/pre-emph defines: http://lists.freedesktop.org/archives/intel-gfx/2014-August/050407.html v2: Creating single macro with argument for slot number (Damien) v3: Adding macro for num of translation entries (Damien) Signed-off-by: Sonika Jindal <sonika.jin...@intel.com> Reviewed-by: Damien Lespiau <damien.lesp...@intel.com> --- drivers/gpu/drm/i915/i915_reg.h | 10 +--------- drivers/gpu/drm/i915/intel_ddi.c | 20 +++++--------------- drivers/gpu/drm/i915/intel_dp.c | 20 ++++++++++---------- 3 files changed, 16 insertions(+), 34 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_reg.h b/drivers/gpu/drm/i915/i915_reg.h index 7a6cc69..7366aac 100644 --- a/drivers/gpu/drm/i915/i915_reg.h +++ b/drivers/gpu/drm/i915/i915_reg.h @@ -5966,15 +5966,7 @@ enum punit_power_well { #define DDI_BUF_CTL_B 0x64100 #define DDI_BUF_CTL(port) _PORT(port, DDI_BUF_CTL_A, DDI_BUF_CTL_B) #define DDI_BUF_CTL_ENABLE (1<<31) -#define DDI_BUF_EMP_400MV_0DB_HSW (0<<24) /* Sel0 */ -#define DDI_BUF_EMP_400MV_3_5DB_HSW (1<<24) /* Sel1 */ -#define DDI_BUF_EMP_400MV_6DB_HSW (2<<24) /* Sel2 */ -#define DDI_BUF_EMP_400MV_9_5DB_HSW (3<<24) /* Sel3 */ -#define DDI_BUF_EMP_600MV_0DB_HSW (4<<24) /* Sel4 */ -#define DDI_BUF_EMP_600MV_3_5DB_HSW (5<<24) /* Sel5 */ -#define DDI_BUF_EMP_600MV_6DB_HSW (6<<24) /* Sel6 */ -#define DDI_BUF_EMP_800MV_0DB_HSW (7<<24) /* Sel7 */ -#define DDI_BUF_EMP_800MV_3_5DB_HSW (8<<24) /* Sel8 */ +#define DDI_BUF_TRANS_SELECT(n) ((n) << 24) #define DDI_BUF_EMP_MASK (0xf<<24) #define DDI_BUF_PORT_REVERSAL (1<<16) #define DDI_BUF_IS_IDLE (1<<7) diff --git a/drivers/gpu/drm/i915/intel_ddi.c b/drivers/gpu/drm/i915/intel_ddi.c index ca1f9a8..c3914b7 100644 --- a/drivers/gpu/drm/i915/intel_ddi.c +++ b/drivers/gpu/drm/i915/intel_ddi.c @@ -241,18 +241,6 @@ void intel_prepare_ddi(struct drm_device *dev) intel_prepare_ddi_buffers(dev, port);
