   7 Required properties:
   8   - compatible: must be "maxim,max30102" or "maxim,max30105"
   9   - reg: the I2C address of the sensor
  10   - interrupt-parent: should be the phandle for the interrupt controller
  11   - interrupts: the sole interrupt generated by the device
  12
  13   Refer to interrupt-controller/interrupts.txt for generic
  14   interrupt client node bindings.

  16 Optional properties:
  17   - maxim,red-led-current-microamp: configuration for red LED current
  18   - maxim,ir-led-current-microamp: configuration for IR LED current
  19   - maxim,green-led-current-microamp: configuration for green LED current
  20     (max30105 only)
  21
  22     Note that each step is approximately 200 microamps, ranging from 0 uA to
  23     50800 uA.
