It is used in mainline imx25.dtsi, but maybe got there by mistake. The according
patches are floating around for a while AFAIK, but haven't made it into mainline.

I am reworking the patch according to Saschas comment and will throw everything
out, that has no mainline driver. I will also include a baseboard .dts, that uses
this .dtsi.

Steffen
