Hi Anatolij,

Thanks for this work.  However, I've got concerns.

Forgive me for ragging on code that you didn't write, but this
fsl_soc.c code for registering the USB device really doesn't belong
here anymore.  It should be part of the drivers/usb/host/ehci-fsl.c
and the driver should do of-style binding (Which should be a lot
easier if I manage to get the merge of platform bus and of_platform
bus into 2.6.35).

This patch series makes the fsl_soc.c code even more complicated, and
scatters what is essentially driver code over even more places in the
arch/powerpc tree.  I'm really not keen on it being merged in this
form.
