As per iio-bindings.txt I did this. It is the same in imx23.dtsi and imx28.dtsi.

http://lxr.free-electrons.com/source/Documentation/devicetree/bindings/iio/iio-bindings.txt#L85
http://lxr.free-electrons.com/source/arch/arm/boot/dts/imx23.dtsi#L570
http://lxr.free-electrons.com/source/arch/arm/boot/dts/imx28.dtsi#L1246

So should this be changed?

Thanks.
