+* NXP LPC32xx SoC ADC controller
+
+Required properties:
+- compatible: must be "nxp,lpc3220-adc"
+- reg: physical base address of the controller and length of memory mapped
+  region.
+- interrupts: The ADC interrupt
+
+Example:
+
+	adc@40048000 {
+		compatible = "nxp,lpc3220-adc";
+		reg = <0x40048000 0x1000>;
+		interrupt-parent = <&mic>;
+		interrupts = <39 0>;

+* 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.
+
+Examples:
+
+	adc: adc@d8200000 {
+		compatible = "st,spear600-adc";
+		reg = <0xd8200000 0x1000>;
+		interrupt-parent = <&vic1>;
+		interrupts = <6>;
+		sampling-frequency = <5000000>;
+		vref-external = <2500>;	/* 2.5V VRef */
