+Freescale vf610 Analog to Digital Converter bindings
+
+The devicetree bindings are for the new ADC driver written for
+vf610/i.MX6slx and upward SoCs from Freescale.
+
+Required properties:
+- compatible: Should contain "fsl,vf610-adc"
+- reg: Offset and length of the register set for the device
+- interrupts: Should contain the interrupt for the device
+- clocks: The clock is needed by the ADC controller, ADC clock source is ipg clock.
+- vref-supply: The regulator supply ADC refrence voltage.
+
+Optional properties:
+- fsl,adc-io-pinctl: Enable field for the I/O port control of MCU pins used as analog inputs.
+ Bit[23:0] correspond to 23 I/O ports, set the relative bit for pointed port.
+
+Example:
+adc0: adc@4003b000 {
+ compatible = "fsl,vf610-adc";
+ reg = <0x4003b000 0x1000>;
+ interrupts = <0 53 0x04>;
+ clocks = <&clks VF610_CLK_ADC0>;
+ clock-names = "adc";
+ status = "disabled";
+};
+
+adc1: adc@400bb000 {
+ compatible = "fsl,vf610-adc";
+ reg = <0x400bb000 0x1000>;
+ interrupts = <0 54 0x04>;
+ clocks = <&clks VF610_CLK_ADC1>;
+ clock-names = "adc";
+ status = "disabled";
+};
+
+&adc0 {
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_adc0_ad5>;
+ fsl,adc-io-pinctl = <0x20>;
+ vref-supply = <®_vcc_3v3_mcu>;
+ status = "okay";
+};
