+Generic resistive touchscreen ADC
+
+Required properties:
+
+ - compatible: must be "resistive-adc-touch"
+The device must be connected to an ADC device that provides channels for
+position measurement and optional pressure.
+Refer to ../iio/iio-bindings.txt for details
+ - iio-channels: must have at least two channels connected to an ADC device.
+These should correspond to the channels exposed by the ADC device and should
+have the right index as the ADC device registers them. These channels
+represent the relative position on the "x" and "y" axes.
+ - iio-channel-names: must have all the channels' names. Mandatory channels
+are "x" and "y".
+
+Optional properties:
+ - iio-channels: The third channel named "pressure" is optional and can be
+used if the ADC device also measures pressure besides position.
+If this channel is missing, pressure will be ignored and the touchscreen
+will only report position.
+ - iio-channel-names: optional channel named "pressure".
+
+Example:
+
+	resistive_touch: resistive_touch {
+		compatible = "resistive-adc-touch";
+		touchscreen-min-pressure = <50000>;
+		io-channels = <&adc 24>, <&adc 25>, <&adc 26>;
