-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.
- - 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>;
-	};
-};
