+Freescale imx7d ADC bindings
+
+The devicetree bindings are for the ADC driver written for
+imx7d SoC.
+
+Required properties:
+- compatible: Should be "fsl,imx7d-adc"
+- reg: Offset and length of the register set for the ADC device
+- interrupts: The interrupt number for the ADC device
+- clocks: The root clock of the ADC controller
+- clock-names: Must contain "adc", matching entry in the clocks property
+- vref-supply: The regulator supply ADC reference voltage
+
+Example:
+adc1: adc@30610000 {
+ compatible = "fsl,imx7d-adc";
+ reg = <0x30610000 0x10000>;
+ interrupts = <GIC_SPI 98 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&clks IMX7D_ADC_ROOT_CLK>;
+ clock-names = "adc";
+ vref-supply = <&reg_vcc_3v3_mcu>;
+};
