	      "brcm,iproc-sba"

  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

	...

	#mbox-cells = <3>;

	...

};



raid0 {

	compatible = "brcm,iproc-sba-v2";

	mboxes = <&raid_mbox 0 0x1 0xffff>,

		 <&raid_mbox 1 0x1 0xffff>,

		 <&raid_mbox 2 0x1 0xffff>,

		 <&raid_mbox 3 0x1 0xffff>,

		 <&raid_mbox 4 0x1 0xffff>,
