Are you sure this is GPL-2.0 only? Didn't you derive it from downstream

This is not a bus of clocks...

Use common suffix or prefix for node names and generic name.

This clock is anyway a bit weird - same frequency as sleep clk.

This is a PMIC pin? So is it a PMIC clk?

Use common suffix or prefix. You already used "-regulator" suffix before.

Status is a last property.
