+Analog Devices AD7606 Simultaneous Sampling ADC
+
+Required properties for the AD7606:
+
+- compatible: Must be one of
+ * "adi,ad7605-4"
+ * "adi,ad7606-8"
+ * "adi,ad7606-6"
+ * "adi,ad7606-4"
+- reg: SPI chip select number for the device
+- spi-max-frequency: Max SPI frequency to use
+ see: Documentation/devicetree/bindings/spi/spi-bus.txt
+- spi-cpha: See Documentation/devicetree/bindings/spi/spi-bus.txt
+- avcc-supply: phandle to the Avcc power supply
+- interrupts: IRQ line for the ADC
+ see: Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
+- adi,conversion-start-gpios: must be the device tree identifier of the CONVST pin.
+ This logic input is used to initiate conversions on the analog
+ input channels. As the line is active high, it should be marked
+ GPIO_ACTIVE_HIGH.
+
+Optional properties:
+
+- reset-gpios: must be the device tree identifier of the RESET pin. If specified,
+ it will be asserted during driver probe. As the line is active high,
+ it should be marked GPIO_ACTIVE_HIGH.
+- standby-gpios: must be the device tree identifier of the STBY pin. This pin is used
+ to place the AD7606 into one of two power-down modes, Standby mode or
+ Shutdown mode. As the line is active low, it should be marked
+ GPIO_ACTIVE_LOW.
+- adi,first-data-gpios: must be the device tree identifier of the FRSTDATA pin.
+ The FRSTDATA output indicates when the first channel, V1, is
+ being read back on either the parallel, byte or serial interface.
+ As the line is active high, it should be marked GPIO_ACTIVE_HIGH.
+- adi,range-gpios: must be the device tree identifier of the RANGE pin. The polarity on
+ this pin determines the input range of the analog input channels. If
+ this pin is tied to a logic high, the analog input range is ±10V for
+ all channels. If this pin is tied to a logic low, the analog input range
+ is ±5V for all channels. As the line is active high, it should be marked
+ GPIO_ACTIVE_HIGH.
+- adi,oversampling-ratio-gpios: must be the device tree identifier of the over-sampling
+ mode pins. As the line is active high, it should be marked
+ GPIO_ACTIVE_HIGH.
+
+Example:
+
+ adc@0 {
+ compatible = "adi,ad7606-8";
+ reg = <0>;
+ spi-max-frequency = <1000000>;
+ spi-cpol;
