Looks good to me.
Tentatively applied this, the DT people may want to say something
about this.

Hi,
I tried the new configuration but the kernel oops when probing the
dm9000 caused by insufficient resources more likely the real reason
that somehow the gpio6: triggers a problem
[ 0.115718] irq: no irq domain found for
/soc/aipi@10000000/iomuxc@10015000/gpio@10015500 !

[ 0.152712] imx27-pinctrl 10015000.iomuxc: initialized IMX pinctrl driver
The imx27-pinctrl driver seems to be initialized after the irq is
requested. So this issue should be the same as in [1].
Regards,
Markus
Markus,
Thank you for point this out! I patched the Linux-next and
my problems went away. I will test now a bit more..
Cheers
