* Texas Instruments' ads124s08 and ads124s06 ADC chip
Required properties:
- compatible :
"ti,ads124s08"
"ti,ads124s06"
- reg : spi chip select number for the device
Recommended properties:
- spi-max-frequency : Definition as per
Documentation/devicetree/bindings/spi/spi-bus.txt
- spi-cpha : Definition as per
Documentation/devicetree/bindings/spi/spi-bus.txt
Optional properties:
- reset-gpios : GPIO pin used to reset the device.
Example:
adc@0 {
compatible = "ti,ads124s08";
reg = <0>;
spi-max-frequency = <1000000>;
spi-cpha;
reset-gpios = <&gpio1 16 GPIO_ACTIVE_LOW>;
};
