+Aspeed ADC
+
+This device is a 10-bit converter for 16 voltage channels. All inputs are
+single ended.
+
+Required properties:
+- compatible: Should be "aspeed,ast2400-adc" or "aspeed,ast2500-adc"
+- reg: memory window mapping address and length
+- clocks: Input clock used to derive the sample clock. Expected to be the
+ SoC's APB clock.
+- #io-channel-cells: Must be set to <1> to indicate channels are selected
+ by index.
+
+Example:
+ adc@1e6e9000 {
+ compatible = "aspeed,ast2400-adc";
+ reg = <0x1e6e9000 0xb0>;
+ clocks = <&clk_apb>;
+ #io-channel-cells = <1>;
+ };
