drm/i915: Configure GEN11_{TBT,TC}_HOTPLUG_CTL for ports TC5/6 (1db9f992) · Commits · 戴 / test

gen11_hpd_detection_setup() is missing ports TC5/6. Add them. TODO: Might be nice to only enable the hpd detection logic for ports we actually have. Should be rolled out for all platforms if/when done... Signed-off-by:
