    1 Maxim MAX30100 heart rate and pulse oximeter sensor
    2 
    3 * https://datasheets.maximintegrated.com/en/ds/MAX30100.pdf
    4 
    5 Required properties:
    6   - compatible: must be "maxim,max30100"
    7   - reg: the I2C address of the sensor
    8   - interrupts: the sole interrupt generated by the device
    9 
   10   Refer to interrupt-controller/interrupts.txt for generic
   11   interrupt client node bindings.
   12 
   13 Optional properties:
   14   - maxim,led-current-microamp: configuration for LED current in microamperes
   15     while the engine is running. First indexed value is the configuration for
   16     the RED LED, and second value is for the IR LED.
   17 
   18     Refer to the datasheet for the allowed current values.
   19 
   20 Example:
   21 
   22 max30100@57 {
   23         compatible = "maxim,max30100";
   24         reg = <0x57>;
   25         maxim,led-current-microamp = <24000 50000>;
   26         interrupt-parent = <&gpio1>;
   27         interrupts = <16 2>;
   28 };
