    Subject[PATCH v5 08/10] drm/vc4: hdmi: Raise the maximum clock rate
    Date
    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.
