+Subject: [PATCH] drm/vc4: hdmi: Raise the maximum clock rate
+
+Now that we have the infrastructure in place, we can raise the maximum
+pixel rate we can reach for HDMI0 on the BCM2711.
+
+HDMI1 is left untouched since its pixelvalve has a smaller FIFO and
+would need a clock faster than what we can provide to support the same
+modes.
