-Required properties:
-- compatible: Should be one of the following
-             "brcm,iproc-sba"
-             "brcm,iproc-sba-v2"
-  The "brcm,iproc-sba" has support for only 6 PQ coefficients
-  The "brcm,iproc-sba-v2" has support for only 30 PQ coefficients
-- mboxes: List of phandle and mailbox channel specifiers
-
-Example:
-
-raid_mbox: mbox@67400000 {
-       ...
-       #mbox-cells = <3>;
-       ...
