+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 controllers.
+ Must be "samsung,exynos-adc-v2" for
+ future controllers.
+- reg: Contains ADC register address range (base address and
+ length) and the address of the phy enable register.
+- 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 binding: handle to adc clock.
+- clock-names From common clock binding: Shall be "adc".
+- vdd-supply VDD input supply.
+
+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>, <0x10040718 0x4>;
+ interrupts = <0 106 0>;
+ #io-channel-cells = <1>;
+ io-channel-ranges;
+
+ clocks = <&clock 303>;
+ clock-names = "adc";
+
+ vdd-supply = <&buck5_reg>;
+};
+
+
+Example: Adding child nodes in dts file
+
+adc@12D10000 {
+
+ /* NTC thermistor is a hwmon device */
+ ncp15wb473@0 {
+ compatible = "ntc,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.
