+Spreadtrum SC27XX series PMICs ADC binding
+
+Required properties:
+- compatible: Should be one of the following.
+ "sprd,sc2720-adc"
+ "sprd,sc2721-adc"
+ "sprd,sc2723-adc"
+ "sprd,sc2730-adc"
+ "sprd,sc2731-adc"
+- reg: The address offset of ADC controller.
+- interrupt-parent: The interrupt controller.
+- interrupts: The interrupt number for the ADC device.
+- #io-channel-cells: Number of cells in an IIO specifier.
+- hwlocks: Reference to a phandle of a hwlock provider node.
+
+Example:
+
+ sc2731_pmic: pmic@0 {
+ compatible = "sprd,sc2731";
+ reg = <0>;
+ spi-max-frequency = <26000000>;
+ interrupts = <GIC_SPI 31 IRQ_TYPE_LEVEL_HIGH>;
+ interrupt-controller;
+ #interrupt-cells = <2>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ pmic_adc: adc@480 {
+ compatible = "sprd,sc2731-adc";
+ reg = <0x480>;
+ interrupt-parent = <&sc2731_pmic>;
+ interrupts = <0 IRQ_TYPE_LEVEL_HIGH>;
+ #io-channel-cells = <1>;
+ hwlocks = <&hwlock 4>;
+ };
+ };
