+* Generic Mailbox Controller and client driver bindings
+
+Generic binding to provide a way for Mailbox controller drivers to
+assign appropriate mailbox channel to client drivers.
+
+* Mailbox Controller
+
+Required property:
+- #mbox-cells: Must be at least 1. Number of cells in a mailbox
+		specifier.
+
+Example:
+	mailbox: mailbox {
+		...
+		#mbox-cells = <1>;
+	};
+
+
+* Mailbox Client
+
+Required property:
+- mboxes: List of phandle and mailbox channel specifiers.
+
+Optional property:
+- mbox-names: List of identifier strings for each mailbox channel.
+- shmem : List of phandle pointing to the shared memory(SHM) area between the
+	  users of these mailboxes for IPC, one for each mailbox. This shared
+	  memory can be part of any memory reserved for the purpose of this
+	  communication between the mailbox client and the remote.
+
+
+Example:
+	pwr_cntrl: power {
+		...
+		mbox-names = "pwr-ctrl", "rpc";
+		mboxes = <&mailbox 0 &mailbox 1>;
+	};
+
+Example with shared memory(shmem):
+
+	sram: sram@50000000 {
+		compatible = "mmio-sram";
+		reg = <0x50000000 0x10000>;
+
+		#address-cells = <1>;
+		#size-cells = <1>;
+		ranges = <0 0x50000000 0x10000>;
+
+		cl_shmem: shmem@0 {
+			compatible = "client-shmem";
+			reg = <0x0 0x200>;
+		};
+	};
+
+	client@2e000000 {
+		...
+		mboxes = <&mailbox 0>;
+		shmem = <&cl_shmem>;
+		..
+	};
