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>;

	};

};
