+Binding documentation for mailbox providers and consumers
+--
+
+Mailbox providers may be represented by any node in a device tree. These
+nodes are designated as mailbox providers. Consumers can then use a phandle
+to a mailbox provider, along with channel specifier information in order to
+get a mailbox.
+
+MAILBOX PROVIDERS
+
+#mbox-cells:
+ Usage: required
+ Type: u32
+ Desc: Number of cells in a mailbox specifier; Typically 1 for nodes
+ which only need a channel index.
+
+
+Example:
+ mailbox: mailbox {
+ #mbox-cells = <1>;
+ ...
+ };
+
+
+MAILBOX CONSUMERS
+
+mbox:
+ Usage: required
+ Type: < [phandle] [mailbox-specifier] >
+ Desc: List of phandle and mailbox specifier pairs, matching provider's
+ #mbox-cells property
+
+mbox-names:
+ Usage: optional
+ Type: string array
+ Desc: List of mailbox input name strings sorted in the same order as
+ the mbox property. Consumer drivers should use mbox-names
+ to match mailbox input names with mailbox specifiers.
+
+Example:
+ consumer {
+ mbox-names = "comms";
+ mbox = <&mailbox 0>;
+ };
