When we use the ethernet device via DT setup, we need to add it
to a lookup list until this is properly handled later in a DT-only
fashion.

In a recent thread

http://thread.gmane.org/gmane.linux.ports.sh.devel/18062/focus=18057

I've been suggested to use OF_DEV_AUXDATA(), isn't this also a case for 
it?

Thanks
Guennadi

AUXDATA seems to be a great way to add a platform data pointer as a
workaround while implementing DT support, but when it comes to
translate the name based on base address the code becomes very
verbose.

I am all for going with the simplest half-way solution that uses the
least amount of lines of code, but I doubt it can get any simpler than
a single line of CLKDEV_DEV_ID().

Thanks,

Apparently I forgot to actually do that.
I have done so now, it is queued up for v3.11 in the soc-r8a7740 branch.
