Hi,
Here is the next revision of Mailbox framwork.
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.
From: Suman Anna
The patch 30058677 "ARM / highbank: add support for pl320 IPC"
added a pl320 IPC specific header file as a generic mailbox.h.
This file has been renamed appropriately to allow the
introduction of the generic mailbox API framework.
