      1* GPIO Decoder DT bindings
      2
      3Required Properties:
      4- compatible: should be "gpio-decoder"
      5- gpios: a spec of gpios (at least two) to be decoded to a number with
      6  first entry representing the MSB.
      7
      8Optional Properties:
      9- decoder-max-value: Maximum possible value that can be reported by
     10  the gpios.
     11- linux,axis: the input subsystem axis to map to (ABS_X/ABS_Y).
     12  Defaults to 0 (ABS_X).
     13
     14Example:
     15	gpio-decoder0 {
     16		compatible = "gpio-decoder";
     17		gpios = <&pca9536 3 GPIO_ACTIVE_HIGH>,
     18			<&pca9536 2 GPIO_ACTIVE_HIGH>,
     19			<&pca9536 1 GPIO_ACTIVE_HIGH>,
     20			<&pca9536 0 GPIO_ACTIVE_HIGH>;
     21		linux,axis = <0>; /* ABS_X */
     22		decoder-max-value = <9>;
     23	};
