--- Comment #6 from Ville Syrjala <ville.syrjala at linux.intel.com> ---
Someone should test this:
--- a/drivers/gpu/drm/i915/display/intel_display_power.c
+++ b/drivers/gpu/drm/i915/display/intel_display_power.c
@@ -423,10 +423,8 @@ icl_combo_phy_aux_power_well_enable(struct

        val = I915_READ(regs->driver);
        I915_WRITE(regs->driver, val | HSW_PWR_WELL_CTL_REQ(pw_idx));

-       if (INTEL_GEN(dev_priv) < 12) {
                val = I915_READ(ICL_PORT_CL_DW12(phy));

Another observation I made was that the 1178 anaovrd w/a is no longer listed
for tgl, so should be nuked. Although it shouldn't matter for this particular
bug.
