Combo PHY A still uses the old ddc pin mapping. From VBT, ddc pin info suggests the following mapping: VBT DRIVER DDI B->ddc_pin=2 should translate to PORT_D->0x9 DDI C->ddc_pin=3 should translate to PORT_E->0xa DDI D->ddc_pin=4 should translate to PORT_F->0xb DDI E->ddc_pin=5 should translate to PORT_G->0xc Adding pin map to facilitate this translation as we cannot use existing icl ddc pin map due to conflict with DDI B and DDI C info. Bspec:20124 v2: Replace IS_ALDERLAKE_S() with HAS_PCH_ADP() as the pin map pairing depends on the PCH being used rather than the platform.(mdroper) Cc: Jani Nikula Cc: Ville Syrjälä Cc: Imre Deak Cc: Matt Roper Cc: Lucas De Marchi Signed-off-by: Aditya Swarup --- drivers/gpu/drm/i915/display/intel_bios.c | 13 +++++++++++- drivers/gpu/drm/i915/display/intel_hdmi.c | 20 ++++++++++++++++++- drivers/gpu/drm/i915/display/intel_vbt_defs.h | 4 ++++ 3 files changed, 35 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_bios.c b/drivers/gpu/drm/i915/display/intel_bios.c index 4cc949b228f2..9dc67c03ffc0 100644 --- a/drivers/gpu/drm/i915/display/intel_bios.c +++ b/drivers/gpu/drm/i915/display/intel_bios.c @@ -1623,12 +1623,23 @@ static const u8 icp_ddc_pin_map[] = { [TGL_DDC_BUS_PORT_6] = GMBUS_PIN_14_TC6_TGP, }; +static const u8 adls_ddc_pin_map[] = { + [ICL_DDC_BUS_DDI_A] = GMBUS_PIN_1_BXT, + [ADLS_DDC_BUS_PORT_TC1] = GMBUS_PIN_9_TC1_ICP, + [ADLS_DDC_BUS_PORT_TC2] = GMBUS_PIN_10_TC2_ICP, + [ADLS_DDC_BUS_PORT_TC3] = GMBUS_PIN_11_TC3_ICP, + [ADLS_DDC_BUS_PORT_TC4] = GMBUS_PIN_12_TC4_ICP, +}; + static u8 map_ddc_pin(struct drm_i915_private *dev_priv, u8 vbt_pin) { const u8 *ddc_pin_map; int n_entries; - if (INTEL_PCH_TYPE(dev_priv) >= PCH_DG1) { + if (HAS_PCH_ADP(dev_priv)) { + ddc_pin_map = adls_ddc_pin_map; + n_entries = ARRAY_SIZE(adls_ddc_pin_map); + } else if (INTEL_PCH_TYPE(dev_priv) >= PCH_DG1) { return vbt_pin; } else if (INTEL_PCH_TYPE(dev_priv) >= PCH_ICP) { ddc_pin_map = icp_ddc_pin_map; diff --git a/drivers/gpu/drm/i915/display/intel_hdmi.c b/drivers/gpu/drm/i915/display/intel_hdmi.c index e10fdb369daa..060a13b63aa9 100644 --- a/drivers/gpu/drm/i915/display/intel_hdmi.c +++ b/drivers/gpu/drm/i915/display/intel_hdmi.c @@ -3135,6 +3135,22 @@ static u8 dg1_port_to_ddc_pin(struct drm_i915_private *dev_priv, enum port port) return intel_port_to_phy(dev_priv, port) + 1; } +static u8 adls_port_to_ddc_pin(struct drm_i915_private *dev_priv, enum port port) +{ + enum phy phy = intel_port_to_phy(dev_priv, port); + + WARN_ON(port == PORT_B || port == PORT_C); + + /* + * Pin mapping for ADL-S requires TC pins for all combo phy outputs + * except first combo output. + */ + if (IS_ALDERLAKE_S(dev_priv) && phy >= PHY_B) + return GMBUS_PIN_9_TC1_ICP + phy - PHY_B; + + return GMBUS_PIN_1_BXT + phy; +} + static u8 g4x_port_to_ddc_pin(struct drm_i915_private *dev_priv, enum port port) { @@ -3172,7 +3188,9 @@ static u8 intel_hdmi_ddc_pin(struct intel_encoder *encoder) return ddc_pin; } - if (INTEL_PCH_TYPE(dev_priv) >= PCH_DG1) + if (IS_ALDERLAKE_S(dev_priv)) + ddc_pin = adls_port_to_ddc_pin(dev_priv, port); + else if (INTEL_PCH_TYPE(dev_priv) >= PCH_DG1) ddc_pin = dg1_port_to_ddc_pin(dev_priv, port); else if (IS_ROCKETLAKE(dev_priv)) ddc_pin = rkl_port_to_ddc_pin(dev_priv, port); diff --git a/drivers/gpu/drm/i915/display/intel_vbt_defs.h b/drivers/gpu/drm/i915/display/intel_vbt_defs.h index 49b4b5fca941..32d1b4f05760 100644 --- a/drivers/gpu/drm/i915/display/intel_vbt_defs.h +++ b/drivers/gpu/drm/i915/display/intel_vbt_defs.h @@ -325,6 +325,10 @@ enum vbt_gmbus_ddi { ICL_DDC_BUS_PORT_4, TGL_DDC_BUS_PORT_5, TGL_DDC_BUS_PORT_6, + ADLS_DDC_BUS_PORT_TC1 = 0x2, + ADLS_DDC_BUS_PORT_TC2, + ADLS_DDC_BUS_PORT_TC3, + ADLS_DDC_BUS_PORT_TC4 }; #define DP_AUX_A 0x40
