+* 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
+ required by the client. The use of this property
+ is discouraged in favor of using index in list of
+ 'mboxes' while requesting a mailbox. Instead the
+ platforms may define channel indices, in DT headers,
+ to something legible.
+
+Example:
+ pwr_cntrl: power {
+ ...
+ mbox-names = "pwr-ctrl", "rpc";
+ mboxes = <&mailbox 0
+ &mailbox 1>;
+ };
