Texas Instruments AFE4404 Heart rate and Pulse Oximeter

Required properties:

  • compatible : Should be “ti,afe4404”.
  • reg : I2C address of the device.
  • tx-supply : Regulator supply to transmitting LEDs.
  • interrupt-parent : Phandle to he parent interrupt controller.
  • interrupts : The interrupt line the device ADC_RDY pin is
           connected to. For details refer to,
           ../interrupt-controller/interrupts.txt.
    

Optional properties:

  • reset-gpios : GPIO used to reset the device.
           For details refer to, ../gpio/gpio.txt.
    

Example:

&i2c2 {
heart_mon@58 {
compatible = “ti,afe4404”;
reg = <0x58>;

    tx-supply = <&vbat>;

    interrupt-parent = <&gpio1>;
    interrupts = <28 IRQ_TYPE_EDGE_RISING>;

    reset-gpios = <&gpio1 16 GPIO_ACTIVE_LOW>;
};
