drm/i915/tgl: allow DVI/HDMI on port A (523e0cc8) · Commits · 戴 / test

Tiger Lake supports HDMI on port A. For other platforms we ignore what the VBT says regarding HDMI to workaround broken VBTs, see commit ("drm/i915/bios: ignore HDMI on port A"). Make this apply gen12+ so they inherit the TGL behavior. Signed-off-by:
