Merge drm/drm-next into drm-misc-next

Parroting Daniel's backmerge justification from
2e79e22e092acd55da0b2db066e4826d7d152c41:

Thierry needs fd70c7755bf0 ("drm/bridge: tc358767: fix max_tu_symbol
value") to be able to merge his dp_link patch series.

+Microcontrollers
+================
+
+Starting from gen9, three microcontrollers are available on the HW: the
+graphics microcontroller (GuC), the HEVC/H.265 microcontroller (HuC) and the
+display microcontroller (DMC). The driver is responsible for loading the
+firmwares on the microcontrollers; the GuC and HuC firmwares are transferred
+to WOPCM using the DMA engine, while the DMC firmware is written through MMIO.
