Add the TI afe4404 heart monitor DT bindings documentation.
Create health directory created under iio.

One little point inline - otherwise this is straightforward and
looks good to me.

Could add cross references to the interrupt and gpio docs.


Will add.

+* Texas Instruments AFE4404 Heart rate and Pulse Oximeter
+
+Required properties:
+ - compatible		: Should be "ti,afe4404".
+ - reg			: I2C address of the device.
+ - tx_sup-supply	: Regulator supply to LEDs.
If the sup bit is for supply I'd drop it and just have
tx-supply.

It is, the name of the pin in the datasheet is "tx_sup", so
I went with that.

+ - interrupt-parent	: Phandle to he parent interrupt controller.
+ - interrupts		: The interrupt line the device ADC_RDY pin is connected to.
+
+Optional properties:
+ - reset-gpios		: GPIO used to reset the device.
+
+Example:
+
+&i2c2 {
+	heart_mon@58 {
+		compatible = "ti,afe4404";
+		reg = <0x58>;
+
+		tx_sup-supply = <&vbat>;
+
+		interrupt-parent = <&gpio1>;
+		interrupts = <28 IRQ_TYPE_EDGE_RISING>;
+
+		reset-gpios = <&gpio1 16 GPIO_ACTIVE_LOW>;
+	};
+};
