Holt Integrated Circuits HI-8435 threshold detector bindings
Required properties:
- compatible: should be "holt,hi8435"
- reg: spi chip select number for the device
Recommended properties:
- spi-max-frequency: definition as per
Documentation/devicetree/bindings/spi/spi-bus.txt
Optional properties:
- gpios: GPIO used for controlling the reset pin
Example:
sensor@0 {
compatible = "holt,hi8435";
reg = <0>;
gpios = <&gpio6 1 0>;
spi-max-frequency = <1000000>;
};
