Except I'd also leave out the artificial clock ID and just use real register offsets from the clock controller base instead. So a single clock controller node for each MMIO range, then set #clock=cells = <1>. Then the binding follows what we have for the interrupts-extended binding for example. If the clock controller optionally needs some data in the dts, that can be added to the clock controller node. Or it can be driver internal built-in data. If the data for dts can be described in a generic way, even better :) This would make the consumer interface look like below with a clock controller node and register offset from it: clocks = <&clock_controller1 0x1234>; Regards, Tony
