From: Ville Syrjälä Date: Thu, 22 Feb 2018 18:10:30 +0000 (+0200) Subject: drm/i915: Add enum aux_ch and clean up the aux init to use it X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=bdabdb635010a3bb973ace5590a61008291d5bd5;p=openwrt%2Fstaging%2Fblogic.git drm/i915: Add enum aux_ch and clean up the aux init to use it Since we no longer have a 1:1 correspondence between ports and AUX channels, let's give AUX channels their own enum. Makes it easier to tell the apples from the oranges, and we get rid of the port E AUX power domain FIXME since we now derive the power domain from the actual AUX CH. v2: Rebase due to AUX F v3: Split out the power domain fix (Rodrigo) Reviewed-by: Rodrigo Vivi #v2 Reviewed-by: Chris Wilson #v2 Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20180222181036.15251-2-ville.syrjala@linux.intel.com --- diff --git a/drivers/gpu/drm/i915/i915_reg.h b/drivers/gpu/drm/i915/i915_reg.h index 2e548fb72170..5af9e529c165 100644 --- a/drivers/gpu/drm/i915/i915_reg.h +++ b/drivers/gpu/drm/i915/i915_reg.h @@ -5353,8 +5353,8 @@ enum { #define _DPF_AUX_CH_DATA4 (dev_priv->info.display_mmio_offset + 0x64520) #define _DPF_AUX_CH_DATA5 (dev_priv->info.display_mmio_offset + 0x64524) -#define DP_AUX_CH_CTL(port) _MMIO_PORT(port, _DPA_AUX_CH_CTL, _DPB_AUX_CH_CTL) -#define DP_AUX_CH_DATA(port, i) _MMIO(_PORT(port, _DPA_AUX_CH_DATA1, _DPB_AUX_CH_DATA1) + (i) * 4) /* 5 registers */ +#define DP_AUX_CH_CTL(aux_ch) _MMIO_PORT(aux_ch, _DPA_AUX_CH_CTL, _DPB_AUX_CH_CTL) +#define DP_AUX_CH_DATA(aux_ch, i) _MMIO(_PORT(aux_ch, _DPA_AUX_CH_DATA1, _DPB_AUX_CH_DATA1) + (i) * 4) /* 5 registers */ #define DP_AUX_CH_CTL_SEND_BUSY (1 << 31) #define DP_AUX_CH_CTL_DONE (1 << 30) @@ -7881,8 +7881,8 @@ enum { #define _PCH_DPD_AUX_CH_DATA4 0xe4320 #define _PCH_DPD_AUX_CH_DATA5 0xe4324 -#define PCH_DP_AUX_CH_CTL(port) _MMIO_PORT((port) - PORT_B, _PCH_DPB_AUX_CH_CTL, _PCH_DPC_AUX_CH_CTL) -#define PCH_DP_AUX_CH_DATA(port, i) _MMIO(_PORT((port) - PORT_B, _PCH_DPB_AUX_CH_DATA1, _PCH_DPC_AUX_CH_DATA1) + (i) * 4) /* 5 registers */ +#define PCH_DP_AUX_CH_CTL(aux_ch) _MMIO_PORT((aux_ch) - AUX_CH_B, _PCH_DPB_AUX_CH_CTL, _PCH_DPC_AUX_CH_CTL) +#define PCH_DP_AUX_CH_DATA(aux_ch, i) _MMIO(_PORT((aux_ch) - AUX_CH_B, _PCH_DPB_AUX_CH_DATA1, _PCH_DPC_AUX_CH_DATA1) + (i) * 4) /* 5 registers */ /* CPT */ #define PORT_TRANS_A_SEL_CPT 0 diff --git a/drivers/gpu/drm/i915/intel_display.h b/drivers/gpu/drm/i915/intel_display.h index c4042e342f50..f5733a2576e7 100644 --- a/drivers/gpu/drm/i915/intel_display.h +++ b/drivers/gpu/drm/i915/intel_display.h @@ -139,6 +139,17 @@ enum dpio_phy { #define I915_NUM_PHYS_VLV 2 +enum aux_ch { + AUX_CH_A, + AUX_CH_B, + AUX_CH_C, + AUX_CH_D, + _AUX_CH_E, /* does not exist */ + AUX_CH_F, +};
