+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";
+ };
