Broadcom BCM2835 VideoCore mailbox IPC



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 {

	compatible = "raspberrypi,firmware";

	mboxes = <&mailbox>;

	#power-domain-cells = <1>;

};
