I can't see why Rob would mind any of the changes made since he
Acked this (and having acked it I doubt he is looking at newer versions!)
so I'm going to take the view his Ack still applies.

Applied to the togreg branch of iio.git which will get pushed out first
as testing for the autobuilders to have a chance to play with it.

Thanks,

Jonathan

+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>;
+	};
