* ST SPEAr ADC device driver
Required properties:
- compatible: Should be "st,spear600-adc"
- reg: Address and length of the register set for the device
- interrupt-parent: Should be the phandle for the interrupt controller
that services interrupts for this device
- interrupts: Should contain the ADC interrupt
- sampling-frequency: Default sampling frequency
Optional properties:
- vref-external: External voltage reference in milli-volts. If omitted
the internal voltage reference will be used.
- average-samples: Number of samples to generate an average value. If
omitted, single data conversion will be used.
