Missing generative AI tags here?

This is more applicable to the second part of the patch, but the 
dependency on the Raspberry Pi firmware interface bothers me a bit. We 
have the AXI PMU blocks available on the 7712/77122 chips which are 
sister chips to the 2712, we don't run the Raspberry Pi firmware on 
those systems however.

Once your patches land, I will see if I can get generative AI to help me 
add support for the two AXI PMUs that exist on those chips.

Thanks for doing this!
