  1. drm/vc4: Remove request for min clocks when hdmi output is disabled 

    Currently, booting with no hdmi connected has:
pi@pi4:~ $ vcgencmd measure_clock hdmi pixel
frequency(9)=120010256
frequency(29)=74988280

After connecting hdmi we get:
pi@pi4:~ $ vcgencmd measure_clock hdmi pixel
frequency(9)=300005856
frequency(29)=149989744

and that persists after disconnecting hdmi

I can measure this on a power supply as [email protected] (52mW).

We should always remove clk_set_min_rate requests
when we no longer need them.
