Subject: [PATCHv9 0/4] Common Mailbox Framework

  Here is the next revision of Mailbox framwork.

Changes since v8:
 o Nits like spelling corrections and a couple symbol renames
 o Made 'mbox-names' optional in favor of index of mailbox
   specifier in 'mboxes' property. Which results in
     mbox_request_channel(struct mbox_client *cl)
     mbox_request_channel(struct mbox_client *cl, int index)
 o Separate out Documentation and Bindings patches.

Changes since v7:
 o Added documentation and example usage.
 o Merged all patches into one that create api, bindings and

Changes since v6:
 o Separate out generic DT bindings patch.
 o Discard unnecessary aligned attributes.

Changes since v5:
 o Use standard error types instead of special type mbox_result.
 o Constify client struct in request_channel
 o Use reinit_completion instead of init_completion every time.
 o Improve commentary in bindings and code.

Changes since v4:
 o Common DT binding for Controller and Client drivers
    As a result, discard string based channel matching
 o Provide for an atomic 'peek' api, that a client could
    call to trigger the controller driver push data upwards.
 o OMAP and Highbank conversion to new api is left out, which
    can be converted later by the developers.

Changes since v3:
 o Change name of symbols from ipc to mbox
 o Return real types instead of void *
 o Align structures
 o Change some symbol names
        rxcb -> rx_callback
        txcb -> tx_done
 o Added kernel-doc for exported API
 o Dropped the cl_id and use clients pointer for callbacks.
 o Fixed locking of channel pool
 o Return negative error code for unsuccessful ipc_send_message()
 o Module referencing during mailbox assignment to a client.
 o Made error code symbols specific to mailbox.
