3 Required properties:
4 - compatible: Should be "st,spear600-adc"
5 - reg: Address and length of the register set for the device
6 - interrupt-parent: Should be the phandle for the interrupt controller
7   that services interrupts for this device
8 - interrupts: Should contain the ADC interrupt
9 - sampling-frequency: Default sampling frequency
10
11 Optional properties:
12 - vref-external: External voltage reference in milli-volts. If omitted
13   the internal voltage reference will be used.
14 - average-samples: Number of samples to generate an average value. If
15   omitted, single data conversion will be used.
