Required properties:

8
  - compatible: must be "maxim,max30102" or "maxim,max30105"

9
  - reg: the I2C address of the sensor

10
  - interrupts: the sole interrupt generated by the device

11


12
  Refer to interrupt-controller/interrupts.txt for generic

13
  interrupt client node bindings.

15
Optional properties:

16
  - maxim,red-led-current-microamp: configuration for red LED current

17
  - maxim,ir-led-current-microamp: configuration for IR LED current

18
  - maxim,green-led-current-microamp: configuration for green LED current

19
    (max30105 only)

21
    Note that each step is approximately 200 microamps, ranging from 0 uA to

22
    50800 uA.
