+Texas Instruments Enhanced Quadrature Encoder Pulse (eQEP) Module
+
+Required properties:
+- compatible:		Must be "ti,am3352-eqep".
+- reg:			Physical base address and size of the registers map.
+- clocks:		Handle to the PWM's functional clock.
+- clock-names:		Must be "fck".
+- interrupts:		Handle to the eQEP event interrupt
+
+Example:
+
+	eqep0: eqep@180 {
+		compatible = "ti,am3352-eqep";
+		reg = <0x180 0x80>;
+		clocks = <&l4ls_gclk>;
+		clock-names = "fck";
+		interrupts = <79>;
+	};
