As mtp_hpd_irq_setup() is reasonably small, prefer to fork it into a new function for Xe2_LPD instead of adding a platform check. v2: Add extra bspec reference and fix missing else (Matt Roper) BSpec: 68970, 69940 Signed-off-by: Gustavo Sousa Signed-off-by: Lucas De Marchi Reviewed-by: Matt Roper --- .../gpu/drm/i915/display/intel_hotplug_irq.c | 21 +++++++++++++++++-- 1 file changed, 19 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_hotplug_irq.c b/drivers/gpu/drm/i915/display/intel_hotplug_irq.c index 3398cc21bd26..f07047e9cb30 100644 --- a/drivers/gpu/drm/i915/display/intel_hotplug_irq.c +++ b/drivers/gpu/drm/i915/display/intel_hotplug_irq.c @@ -163,7 +163,9 @@ static void intel_hpd_init_pins(struct drm_i915_private *dev_priv) (!HAS_PCH_SPLIT(dev_priv) || HAS_PCH_NOP(dev_priv))) return; - if (INTEL_PCH_TYPE(dev_priv) >= PCH_DG1) + if (INTEL_PCH_TYPE(dev_priv) >= PCH_LNL) + hpd->pch_hpd = hpd_mtp; + else if (INTEL_PCH_TYPE(dev_priv) >= PCH_DG1) hpd->pch_hpd = hpd_sde_dg1; else if (INTEL_PCH_TYPE(dev_priv) >= PCH_MTP) hpd->pch_hpd = hpd_mtp; @@ -1063,6 +1065,19 @@ static void mtp_hpd_irq_setup(struct drm_i915_private *i915) mtp_tc_hpd_detection_setup(i915); } +static void xe2lpd_sde_hpd_irq_setup(struct drm_i915_private *i915) +{ + u32 hotplug_irqs, enabled_irqs; + + enabled_irqs = intel_hpd_enabled_irqs(i915, i915->display.hotplug.pch_hpd); + hotplug_irqs = intel_hpd_hotplug_irqs(i915, i915->display.hotplug.pch_hpd); + + ibx_display_interrupt_update(i915, hotplug_irqs, enabled_irqs); + + mtp_ddi_hpd_detection_setup(i915); + mtp_tc_hpd_detection_setup(i915); +} + static bool is_xelpdp_pica_hpd_pin(enum hpd_pin hpd_pin) { return hpd_pin >= HPD_PORT_TC1 && hpd_pin <= HPD_PORT_TC4; @@ -1122,7 +1137,9 @@ static void xelpdp_hpd_irq_setup(struct drm_i915_private *i915) xelpdp_pica_hpd_detection_setup(i915); - if (INTEL_PCH_TYPE(i915) >= PCH_MTP) + if (INTEL_PCH_TYPE(i915) >= PCH_LNL) + xe2lpd_sde_hpd_irq_setup(i915); + else if (INTEL_PCH_TYPE(i915) >= PCH_MTP) mtp_hpd_irq_setup(i915); }
