From fb81cbe46988cddfd9e6fd2bb9f7ce39cea0c380 Mon Sep 17 00:00:00 2001 From: Lucas De Marchi Date: Thu, 11 Jul 2019 10:31:12 -0700 Subject: [PATCH] drm/i915/tgl: port to ddc pin mapping Make the icl function generic so it is based on phy type and can be applied to tgl as well. I checked if this could not apply to EHL as well, but unfortunately there the HPD and DDC/GMBUS pins for DDI C are mapped to TypeC Port 1 even though it doesn't have TC phy. v2: don't add a separate function for TGL, but rather reuse the ICL one (suggested by Rodrigo) v3: rebase after the introduction of enum phy and use it for the conversions Cc: Anusha Srivatsa Cc: Rodrigo Vivi Signed-off-by: Lucas De Marchi Reviewed-by: Matt Roper Link: https://patchwork.freedesktop.org/patch/msgid/20190711173115.28296-19-lucas.demarchi@intel.com --- drivers/gpu/drm/i915/display/intel_hdmi.c | 36 ++++++----------------- 1 file changed, 9 insertions(+), 27 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_hdmi.c b/drivers/gpu/drm/i915/display/intel_hdmi.c index 0ebec69bbbfc..77af0dfd93ce 100644 --- a/drivers/gpu/drm/i915/display/intel_hdmi.c +++ b/drivers/gpu/drm/i915/display/intel_hdmi.c @@ -2930,33 +2930,15 @@ static u8 cnp_port_to_ddc_pin(struct drm_i915_private *dev_priv, static u8 icl_port_to_ddc_pin(struct drm_i915_private *dev_priv, enum port port) { - u8 ddc_pin; + enum phy phy = intel_port_to_phy(dev_priv, port); - switch (port) { - case PORT_A: - ddc_pin = GMBUS_PIN_1_BXT; - break; - case PORT_B: - ddc_pin = GMBUS_PIN_2_BXT; - break; - case PORT_C: - ddc_pin = GMBUS_PIN_9_TC1_ICP; - break; - case PORT_D: - ddc_pin = GMBUS_PIN_10_TC2_ICP; - break; - case PORT_E: - ddc_pin = GMBUS_PIN_11_TC3_ICP; - break; - case PORT_F: - ddc_pin = GMBUS_PIN_12_TC4_ICP; - break; - default: - MISSING_CASE(port); - ddc_pin = GMBUS_PIN_2_BXT; - break; - } - return ddc_pin; + if (intel_phy_is_combo(dev_priv, phy)) + return GMBUS_PIN_1_BXT + port; + else if (intel_phy_is_tc(dev_priv, phy)) + return GMBUS_PIN_9_TC1_ICP + intel_port_to_tc(dev_priv, port); + + WARN(1, "Unknown port:%c\n", port_name(port)); + return GMBUS_PIN_2_BXT; } static u8 mcc_port_to_ddc_pin(struct drm_i915_private *dev_priv, enum port port) @@ -3019,7 +3001,7 @@ static u8 intel_hdmi_ddc_pin(struct drm_i915_private *dev_priv, if (HAS_PCH_MCC(dev_priv)) ddc_pin = mcc_port_to_ddc_pin(dev_priv, port); - else if (HAS_PCH_ICP(dev_priv)) + else if (HAS_PCH_TGP(dev_priv) || HAS_PCH_ICP(dev_priv)) ddc_pin = icl_port_to_ddc_pin(dev_priv, port); else if (HAS_PCH_CNP(dev_priv)) ddc_pin = cnp_port_to_ddc_pin(dev_priv, port);
