3Required properties:
4- compatible: Should be one of the following.
5	"sprd,sc2720-adc"
6	"sprd,sc2721-adc"
7	"sprd,sc2723-adc"
8	"sprd,sc2730-adc"
9	"sprd,sc2731-adc"
10- reg: The address offset of ADC controller.
11- interrupt-parent: The interrupt controller.
12- interrupts: The interrupt number for the ADC device.
13- #io-channel-cells: Number of cells in an IIO specifier.
14- hwlocks: Reference to a phandle of a hwlock provider node.
