+- AD7781:
+ * https://www.analog.com/media/en/technical-documentation/data-sheets/AD7781.pdf
+
+Required properties:
+
+- compatible: should be one of
+ * "adi,ad7170"
+ * "adi,ad7171"
+ * "adi,ad7780"
+ * "adi,ad7781"
+- reg: spi chip select number for the device
+- vref-supply: the regulator supply for the ADC reference voltage
+
+Optional properties:
+
+- powerdown-gpios: must be the device tree identifier of the PDRST pin. If
+ specified, it will be asserted during driver probe. As the
+ line is active high, it should be marked GPIO_ACTIVE_HIGH.
+- adi,gain-gpios: must be the device tree identifier of the GAIN pin. Only for
+ the ad778x chips. If specified, it will be asserted during
+ driver probe. As the line is active low, it should be marked
+ GPIO_ACTIVE_LOW.
+- adi,filter-gpios: must be the device tree identifier of the FILTER pin. Only
+ for the ad778x chips. If specified, it will be asserted
+ during driver probe. As the line is active low, it should be
+ marked GPIO_ACTIVE_LOW.
+
+Example:
+
+adc@0 {
+ compatible = "adi,ad7780";
+ reg = <0>;
+ vref-supply = <&vdd_supply>
+
+ powerdown-gpios = <&gpio 12 GPIO_ACTIVE_HIGH>;
+ adi,gain-gpios = <&gpio 5 GPIO_ACTIVE_LOW>;
+ adi,filter-gpios = <&gpio 15 GPIO_ACTIVE_LOW>;
