+FlexTimer Quadrature decoder counter
+
+This driver exposes a simple counter for the quadrature decoder mode.
+
+Required properties:
+- compatible:		Must be "fsl,ftm-quaddec".
+- reg:			Must be set to the memory region of the flextimer.
+
+Optional property:
+- big-endian:		Access the device registers in big-endian mode.
+
+Example:
+		counter0: counter@29d0000 {
+			compatible = "fsl,ftm-quaddec";
+			reg = <0x0 0x29d0000 0x0 0x10000>;
+			big-endian;
+			status = "disabled";
+		};
