From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx>
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,afe4403".
- - reg : SPI chip select address of 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.
-
-For other required and optional properties of SPI slave nodes
-please refer to ../../spi/spi-bus.txt.

-Example:
-
-&spi0 {
- heart_mon@0 {
- compatible = "ti,afe4403";
- reg = <0>;
- spi-max-frequency = <10000000>;

-
- interrupt-parent = <&gpio1>;
- interrupts = <28 IRQ_TYPE_EDGE_RISING>;
-
- reset-gpios = <&gpio1 16 GPIO_ACTIVE_LOW>;
