+* 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.
