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>;
+ };
+};
