-Freescale DCP (Data Co-Processor) found on i.MX23/i.MX28 .
-
-Required properties:
-- compatible : Should be "fsl,<soc>-dcp"
-- reg : Should contain MXS DCP registers location and length
-- interrupts : Should contain MXS DCP interrupt numbers, VMI IRQ and DCP IRQ
-               must be supplied, optionally Secure IRQ can be present, but
-	       is currently not implemented and not used.
-- clocks : Clock reference (only required on some SOCs: 6ull and 6sll).
-- clock-names : Must be "dcp".
-
-Example:
-
-dcp: crypto@...28000 {
-	compatible = "fsl,imx28-dcp", "fsl,imx23-dcp";
-	reg = <0x80028000 0x2000>;
-	interrupts = <52 53>;
-};
