| See bindings/interrupt-controller/brcm,bcm2835-armctrl-ic.txt | |
| - #mbox-cells: Specifies the number of cells needed to encode a mailbox | |
| channel. The value shall be 0, since there is only one | |

| Example: | |
| mailbox: mailbox@7e00b880 { | |
| compatible = "brcm,bcm2835-mbox"; | |
| reg = <0x7e00b880 0x40>; | |
| interrupts = <0 1>; | |
| #mbox-cells = <0>; | |
| }; | |
| firmware: firmware { | |
| compatible = "raspberrypi,firmware"; | |
| mboxes = <&mailbox>; | |
| #power-domain-cells = <1>; | |
