+* Freescale i.MX PATA Controller
+
+Required properties:
+- compatible: "fsl,imx27-pata"
+- reg: Address range of the PATA Controller
+- interrupts: The interrupt of the PATA Controller
+- clocks: the clocks for the PATA Controller
+
+Example:
+
+       pata: pata@83fe0000 {
+               compatible = "fsl,imx51-pata", "fsl,imx27-pata";
+               reg = <0x83fe0000 0x4000>;
+               interrupts = <70>;
+               clocks = <&clks 161>;
+               status = "disabled";
+       };
