Required properties:
compatible: must be “maxim,max30102” or “maxim,max30105”
reg: the I2C address of the sensor
interrupt-parent: should be the phandle for the interrupt controller
interrupts: the sole interrupt generated by the device
Refer to interrupt-controller/interrupts.txt for generic
interrupt client node bindings.
Optional properties:
maxim,red-led-current-microamp: configuration for red LED current
maxim,ir-led-current-microamp: configuration for IR LED current
maxim,green-led-current-microamp: configuration for green LED current
(max30105 only)Note that each step is approximately 200 microamps, ranging from 0 uA to
50800 uA.
Example:
max30102@57 {
compatible = “maxim,max30102”;
reg = <0x57>;
maxim,red-led-current-microamp = <7000>;
maxim,ir-led-current-microamp = <7000>;
interrupt-parent = <&gpio1>;
interrupts = <16 2>;
};
