+Samsung Exynos Analog to Digital Converter bindings
+
+The devicetree bindings are for the new ADC driver written for
+Exynos4 and upward SoCs from Samsung.
+
+New driver handles the following
+1. Supports ADC IF found on EXYNOS4412/EXYNOS5250
+   and future SoCs from Samsung
+2. Add ADC driver under iio/adc framework
+3. Also adds the Documentation for device tree bindings
+
+Required properties:
+- compatible:		Must be "samsung,exynos-adc-v1"
+				for exynos4412/5250 and s5pv210 controllers.
+			Must be "samsung,exynos-adc-v2" for
+				future controllers.
+			Must be "samsung,exynos3250-adc" for
+				controllers compatible with ADC of Exynos3250.
+			Must be "samsung,exynos7-adc" for
+				the ADC in Exynos7 and compatibles
+			Must be "samsung,s3c2410-adc" for
+				the ADC in s3c2410 and compatibles
+			Must be "samsung,s3c2416-adc" for
+				the ADC in s3c2416 and compatibles
+			Must be "samsung,s3c2440-adc" for
+				the ADC in s3c2440 and compatibles
+			Must be "samsung,s3c2443-adc" for
+				the ADC in s3c2443 and compatibles
+			Must be "samsung,s3c6410-adc" for
+				the ADC in s3c6410 and compatibles
+- reg:			List of ADC register address range
+			- The base address and range of ADC register
+			- The base address and range of ADC_PHY register (every
+			  SoC except for s3c24xx/s3c64xx ADC)
+- interrupts: 		Contains the interrupt information for the timer. The
+			format is being dependent on which interrupt controller
+			the Samsung device uses.
+- #io-channel-cells = <1>; As ADC has multiple outputs
+- clocks		From common clock bindings: handles to clocks specified
+			in "clock-names" property, in the same order.
+- clock-names		From common clock bindings: list of clock input names
+			used by ADC block:
+			- "adc" : ADC bus clock
+			- "sclk" : ADC special clock (only for Exynos3250 and
+				   compatible ADC block)
+- vdd-supply		VDD input supply.
+
+- samsung,syscon-phandle Contains the PMU system controller node
+			(To access the ADC_PHY register on Exynos5250/5420/5800/3250)
+Optional properties:
+- has-touchscreen:	If present, indicates that a touchscreen is
+			connected an usable.
+
+Note: child nodes can be added for auto probing from device tree.
+
+Example: adding device info in dtsi file
+
+adc: adc@12d10000 {
+	compatible = "samsung,exynos-adc-v1";
+	reg = <0x12D10000 0x100>;
+	interrupts = <0 106 0>;
+	#io-channel-cells = <1>;
+	io-channel-ranges;
+
+	clocks = <&clock 303>;
+	clock-names = "adc";
+
+	vdd-supply = <&buck5_reg>;
+	samsung,syscon-phandle = <&pmu_system_controller>;
+};
+
+Example: adding device info in dtsi file for Exynos3250 with additional sclk
+
+adc: adc@126c0000 {
+	compatible = "samsung,exynos3250-adc", "samsung,exynos-adc-v2;
+	reg = <0x126C0000 0x100>;

+	clock-names = "adc", "sclk";
+
+	vdd-supply = <&buck5_reg>;
+	samsung,syscon-phandle = <&pmu_system_controller>;
+};
+
+Example: Adding child nodes in dts file
+
+adc@12d10000 {
+
+	/* NTC thermistor is a hwmon device */
+	ncp15wb473@0 {
+		compatible = "murata,ncp15wb473";
+		pullup-uv = <1800000>;
+		pullup-ohm = <47000>;
+		pulldown-ohm = <0>;
+		io-channels = <&adc 4>;
+	};
+};
+
+Note: Does not apply to ADC driver under arch/arm/plat-samsung/
+Note: The child node can be added under the adc node or separately.
