6- reg : 	physical base address of the mailbox and length of
7		memory mapped region.
8- #mbox-cells:	Common mailbox binding property to identify the number
9		of cells required for the mailbox specifier. Should be 1.

11Optional properties:
12- interrupt-parent :	interrupt source phandle.
13- interrupts :		interrupt number. The interrupt specifier format

16Example:
17	mbox_tx: mailbox@0x100 {
18		compatible = "altr,mailbox-1.0";
19		reg = <0x100 0x8>;
20		interrupt-parent = < &gic_0 >;
21		interrupts = <5>;
22		#mbox-cells = <1>;
23	};
24
25	mbox_rx: mailbox@0x200 {
26		compatible = "altr,mailbox-1.0";
27		reg = <0x200 0x8>;
28		interrupt-parent = < &gic_0 >;
29		interrupts = <6>;
30		#mbox-cells = <1>;

33Mailbox client
34===============
35"mboxes" and the optional "mbox-names" (please see
36Documentation/devicetree/bindings/mailbox/mailbox.txt for details). Each value
37of the mboxes property should contain a phandle to the mailbox controller
38device node and second argument is the channel index. It must be 0 (hardware
39support only one channel).The equivalent "mbox-names" property value can be
40used to give a name to the communication channel to be used by the client user.

42Example:
43	mclient0: mclient0@0x400 {
44		compatible = "client-1.0";
45		reg = <0x400 0x10>;
46		mbox-names = "mbox-tx", "mbox-rx";
47		mboxes = <&mbox_tx 0>,
48			 <&mbox_rx 0>;
