Analog Devices AD7768-1 ADC device driver



Required properties for the AD7768-1:



- compatible: Must be "adi,ad7768-1"

- reg: SPI chip select number for the device

- spi-max-frequency: Max SPI frequency to use

	see: Documentation/devicetree/bindings/spi/spi-bus.txt

- clocks: phandle to the master clock (mclk)

	see: Documentation/devicetree/bindings/clock/clock-bindings.txt

- clock-names: Must be "mclk".

- interrupts: IRQ line for the ADC

	see: Documentation/devicetree/bindings/interrupt-controller/interrupts.txt

- vref-supply: vref supply can be used as reference for conversion

- adi,sync-in-gpios: must be the device tree identifier of the SYNC-IN pin. Enables

	synchronization of multiple devices that require simultaneous sampling.

	A pulse is always required if the configuration is changed in any way, for example

	if the filter decimation rate changes. As the line is active low, it should

	be marked GPIO_ACTIVE_LOW.



Optional properties:



 - reset-gpios : GPIO spec for the RESET pin. 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,ad7768-1";

		reg = <0>;

		spi-max-frequency = <2000000>;

		spi-cpol;

		spi-cpha;

		vref-supply = <&adc_vref>;

		interrupts = <25 IRQ_TYPE_EDGE_RISING>;

		interrupt-parent = <&gpio>;

		adi,sync-in-gpios = <&gpio 22 GPIO_ACTIVE_LOW>;

		reset-gpios = <&gpio 27 GPIO_ACTIVE_LOW>;

		clocks = <&ad7768_mclk>;

		clock-names = "mclk";

	};
