+* Freescale enhanced Multimedia Accelerator (eMMA) video Pre-processor (PrP)
+ for i.MX.
+
+Required properties:
+- compatible : Shall contain "fsl,imx21-emmaprp".
+- 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";
+ };
