Imre Deak 9cb1547891 drm/i915/dp_mst: Work around Thunderbolt sink disconnect after SINK_COUNT_ESI read ... Due to a problem in the iTBT DP-in adapter's firmware the sink on a TBT link may get disconnected inadvertently if the SINK_COUNT_ESI and the DP_LINK_SERVICE_IRQ_VECTOR_ESI0 registers are read in a single AUX transaction. Work around the issue by reading these registers in separate transactions. The issue affects MTL+ platforms and will be fixed in the DP-in adapter firmware, however releasing that firmware fix may take some time and is not guaranteed to be available for all systems. Based on this apply the workaround on affected platforms. See HSD #13013007775. v2: Cc'ing Mika Westerberg.
