Kernel-4.18.0-80.el8_afe4403

Texas Instruments AFE4403 Heart rate and Pulse Oximeter

Required properties:

• compatible : Should be “ti,afe4403”.
• reg : SPI chip select address of 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.
  

For other required and optional properties of SPI slave nodes
please refer to ../../spi/spi-bus.txt.

Example:

&spi0 {
heart_mon@0 {
compatible = “ti,afe4403”;
reg = <0>;
spi-max-frequency = <10000000>;

    tx-supply = <&vbat>;

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

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

};
