+Required properties:
+ - compatible		: Should be "ti,afe4403".
+ - reg			: SPI chip select address of device.
+ - tx-supply		: Regulator supply to transmitting LEDs.
+ - interrupt-parent	: Phandle to he parent interrupt controller.
+ - interrupts		: The interrupt line the device ADC_RDY pin is
+			  connected to. For details refer to,
