0006 - reg: Specifies base physical address and size of the registers
0007 - interrupts: The interrupt number
0008 See bindings/interrupt-controller/brcm,bcm2835-armctrl-ic.txt
0009 - #mbox-cells: Specifies the number of cells needed to encode a mailbox
0010 channel. The value shall be 0, since there is only one
0011 mailbox channel implemented by the device.

0013 Example:
0014
0015 mailbox: mailbox@7e00b880 {
0016 compatible = "brcm,bcm2835-mbox";
0017 reg = <0x7e00b880 0x40>;
0018 interrupts = <0 1>;
0019 #mbox-cells = <0>;
0020 };
0021
0022 firmware: firmware {
0023 compatible = "raspberrypi,firmware";
0024 mboxes = <&mailbox>;
0025 #power-domain-cells = <1>;
0026 };
