[PATCH 08/46] dt-bindings:iio:health:ti,afe4404: txt to yaml conversion

[Jonathan Cameron <jic23@kernel.org>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

This basically has same questions as for the afe4403.  We could combine
the two bindings, but as the drivers are separate and it would be a little
fiddly due to different buses let's keep the separating.
To repeat questions from the ti,afe4403 binding.

A few questions came up whilst converting this one.
1) What is actually required?
   - Checking Linux driver, interrupt is not, and the tx-supply could
     be supplied by a stub regulator as long as it's always on.
     As such I have reduced the required list to just compatible and reg.
2) What is the regulator called?
   - It's tx-supply in the binding doc, but the driver request tx_sup
     I've left this alone for now.  Andrew could you confirm what is
     intended for this?

-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.

-		tx-supply = <&vbat>;

-
-		reset-gpios = <&gpio1 16 GPIO_ACTIVE_LOW>;
-	};
