Maxim MAX30102 heart rate and pulse oximeter sensor



* https://datasheets.maximintegrated.com/en/ds/MAX30102.pdf



Required properties:

  - compatible: must be "maxim,max30102"

  - 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



    Note that each step is approximately 200 microamps, ranging from 0 uA to

    50800 uA.



Example:



max30100@57 {

	compatible = "maxim,max30102";

	reg = <0x57>;

	maxim,red-led-current-microamp = <7000>;

	maxim,ir-led-current-microamp = <7000>;

	interrupt-parent = <&gpio1>;

	interrupts = <16 2>;

};
