Could you please check that this seems to work properly? PS. We don't need power-domain-names. Regards, Bjorn > reg = <0x01800000 0x80000>; > }; > > -- > 2.25.1 >

Add RPM power domain for clk controller so that clock controller can use it for dynamic voltage frequency scaling. Also replace the RPM power domain value with defninition.
