+* Freescale enhanced Multimedia Accelerator (eMMA) video Pre-processor (PrP)
+  for i.MX21 & i.MX27 SoCs.
+
+Required properties:
+- compatible : Shall contain "fsl,imx21-emmaprp" for compatible with
+               the one integrated on i.MX21 SoC.
+- reg        : Offset and length of the register set for the device.
+- interrupts : Should contain eMMA PrP interrupt number.
+- clocks     : Should contain the ahb and ipg clocks, in the order
+               determined by the clock-names property.
+- clock-names: Should be "ahb", "ipg".
+
+Example:
+	emmaprp: emmaprp@10026400 {
+		compatible = "fsl,imx27-emmaprp", "fsl,imx21-emmaprp";
+		reg = <0x10026400 0x100>;
+		interrupts = <51>;
+		clocks = <&clks 49>, <&clks 68>;
+		clock-names = "ipg", "ahb";
+	};
