Merge v5.4-rc4 into drm-next
Thierry needs fd70c7755bf0 ("drm/bridge: tc358767: fix max_tu_symbol value") to be able to merge his dp_link patch series. Some adjacent changes conflicts, plus some clashes in i915 due to cherry-picking and git trying to be helpful and leaving both versions in. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
