Lower case hex, please. ...and pad the address to 8 digits here (just
don't do it in the unit address in the node name).

The order of "reg" and "reg-names" needs to match the bindings
exactly. It's almost certainly easier to change your device tree since
the bindings have already landed.

That means that "lpass-hdmiif" will be first. ...and it will also
change your node name since the first "reg" listed will now be
3987000.

power-domain-names is not in the bindings.

Clocks do not match bindings.

interrupt-names ordering does not match bindings.
