     12description: |
     13  The hardware message box on sun6i, sun8i, sun9i, and sun50i SoCs is a
     14  two-user mailbox controller containing 8 unidirectional FIFOs. An interrupt
     15  is raised for received messages, but software must poll to know when a
     16  transmitted message has been acknowledged by the remote user. Each FIFO can
     17  hold four 32-bit messages; when a FIFO is full, clients must wait before
     18  attempting more transmissions.

     20  Refer to ./mailbox.txt for generic information about mailbox device-tree
     21  bindings.
