Maxim MAX30102 heart rate and pulse oximeter sensor Maxim MAX30105 optical particle-sensing module * https://datasheets.maximintegrated.com/en/ds/MAX30102.pdf * https://datasheets.maximintegrated.com/en/ds/MAX30105.pdf Required properties: - compatible: must be "maxim,max30102" or "maxim,max30105" - reg: the I2C address of the sensor - 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>; };
