On the commit 3301d409 ("drm/i915: PSR: Fix DP_PSR_NO_TRAIN_ON_EXIT logic")' we already had identified that DP_PSR_NO_TRAIN_ON_EXIT doesn't mean we shouldn't send TPS patterns, however we start sending the minimal TP1 as possible and no TP2. For most of the panels this is ok, but we found a reported case where this is not true and panel keeps frozen without updating the screen for a while. We could just get this case after patch "PSR: Don't Skip aux handshake on DP_PSR_NO_TRAIN_ON_EXIT." is applied since that one fix the hard freeze on this kind of panels.
