1* Generic Mailbox Controller and client driver bindings
2

4assign appropriate mailbox channel to client drivers.

6* Mailbox Controller
7
8Required property:
9- #mbox-cells: Must be at least 1. Number of cells in a mailbox
10 specifier.
11
12Example:
13 mailbox: mailbox {
14 ...
15 #mbox-cells = <1>;
16 };
17
18
19* Mailbox Client
20
21Required property:
22- mboxes: List of phandle and mailbox channel specifiers.
23
24Optional property:
25- mbox-names: List of identifier strings for each mailbox channel
26 required by the client. The use of this property
27 is discouraged in favor of using index in list of
28 'mboxes' while requesting a mailbox. Instead the
29 platforms may define channel indices, in DT headers,
30 to something legible.
31
32Example:
33 pwr_cntrl: power {
34 ...
35 mbox-names = "pwr-ctrl", "rpc";
36 mboxes = <&mailbox 0
37 &mailbox 1>;
38 };
