16 - compatible: should be one of
21 - reg: spi chip select number for the device
22 - vref-supply: the regulator supply for the ADC reference voltage
26 - powerdown-gpios: must be the device tree identifier of the PDRST pin. If
27 specified, it will be asserted during driver probe. As the
28 line is active high, it should be marked GPIO_ACTIVE_HIGH.
29 - adi,gain-gpios: must be the device tree identifier of the GAIN pin. Only for
30 the ad778x chips. If specified, it will be asserted during
31 driver probe. As the line is active low, it should be marked
33 - adi,filter-gpios: must be the device tree identifier of the FILTER pin. Only
34 for the ad778x chips. If specified, it will be asserted
35 during driver probe. As the line is active low, it should be
36 marked GPIO_ACTIVE_LOW.
