+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";
+               };
