- reg: physical base address of the controller and length of memory mapped

  region.



- #clock-cells: should be 1.



Optional Properties:



- mboxes: Phandle to the mailbox for sending message to MCU.

            (See: ../mailbox/hisilicon,hi3660-mailbox.txt for more info)



Each clock is assigned an identifier and client nodes use this identifier

to specify the clock which they consume.
