From 523e0cc89b83c4caa98e2955762e35f1688e11ed Mon Sep 17 00:00:00 2001 From: Lucas De Marchi Date: Tue, 12 Nov 2019 18:19:35 -0800 Subject: [PATCH] drm/i915/tgl: allow DVI/HDMI on port A Tiger Lake supports HDMI on port A. For other platforms we ignore what the VBT says regarding HDMI to workaround broken VBTs, see commit 2ba7d7e04371 ("drm/i915/bios: ignore HDMI on port A"). Make this apply gen12+ so they inherit the TGL behavior.
