From 4f7dad584fdce914d698233179a1188481789884 Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Tue, 21 Sep 2021 03:23:02 +0300 Subject: [PATCH] drm/i915/adlp/tc: Fix PHY connected check for Thunderbolt mode MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit On ADL-P the PHY ready (aka status complete on other platforms) flag is always set, besides when a DP-alt, legacy sink is connected also when a TBT sink is connected or nothing is connected. So assume the PHY to be connected when both the TBT live status and PHY ready flags are set.
