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>;
|
|
};
