- "hisilicon,hi3660-iomcu"
- "hisilicon,hi3660-stub-clk"
- 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.
