Sounds good. Since it sounds like the hardware is available in all imx27 device, maybe someone else can test your driver on an imx27 board that already has partial DT support when you add it to arch/arm/boot/dts/imx27.dtsi? Is there any reason why an imx27 based board would not support this driver? Are there any other chips that could use it, e.g. imx25 or imx6? Arnd
