+Subject: [PATCH] drm/vc4: hdmi: Add a set_timings callback
+
+Similarly to the previous patches, the timings setup in the HDMI controller
+of the BCM2711 is slightly different, mostly because it supports higher
+resolutions and thus needed more spaces for the various timings, resulting
+in the register layout changing.
+
+Let's add a callback for that as well.
