   4 Subject: [PATCH] drm/vc4: hdmi: Raise the maximum clock rate
   5
   6 Now that we have the infrastructure in place, we can raise the maximum
   7 pixel rate we can reach for HDMI0 on the BCM2711.
   8
   9 HDMI1 is left untouched since its pixelvalve has a smaller FIFO and
  10 would need a clock faster than what we can provide to support the same
  11 modes.
