3Required properties:
4 - compatible		: Should be "ti,afe4403".
5 - reg			: SPI chip select address of device.
6 - tx-supply		: Regulator supply to transmitting LEDs.
7 - interrupts		: The interrupt line the device ADC_RDY pin is
8			  connected to. For details refer to,
9			  ../../interrupt-controller/interrupts.txt.
10
11Optional properties:
12 - reset-gpios		: GPIO used to reset the device.
13			  For details refer to, ../../gpio/gpio.txt.
