+* Texas Instruments - AFE4403 Heart rate and Pulse Oximeter
+
+The device consists of a low-noise receiver channel
+with an integrated analog-to-digital converter (ADC),
+an LED transmit section, and diagnostics for sensor and LED fault detection.
+
+Required properties:
+ - compatible: Must contain "ti,afe4403".
+ - ste-gpio: GPIO for the spi control line
+ - data-ready-gpio: GPIO interrupt when the afe4403 has data
+ - led-supply: Chip supply to the device
+
+Optional properties:
+ - reset-gpio: GPIO used to reset the device via HW
+
+Example:
+
+&heart_rate {
+ compatible = "ti,afe4403";
+ ste-gpio = <&gpio1 29 GPIO_ACTIVE_HIGH>;
+ data-ready-gpio = <&gpio1 28 GPIO_ACTIVE_HIGH>;
+ led-supply = <&vbat>;
+};
