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

42	mclient0: mclient0@400 {
43		compatible = "client-1.0";
44		reg = <0x400 0x10>;
45		mbox-names = "mbox-tx", "mbox-rx";
46		mboxes = <&mbox_tx 0>,
47			 <&mbox_rx 0>;
