-Required properties:
-
-- compatible: Should be "brcm,bcm2835-mbox"
-- reg: Specifies base physical address and size of the registers
-- interrupts: The interrupt number
- 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
- mailbox channel implemented by the device.

-Example:
-
-mailbox: mailbox@7e00b880 {
- compatible = "brcm,bcm2835-mbox";
- reg = <0x7e00b880 0x40>;
- interrupts = <0 1>;
- #mbox-cells = <0>;
-};

-firmware: firmware {
