My vote is, and always has been 'generic-uio' :)

Putting some random vendor/device string in there is just nuts. Do you
really want a kernel patch every time some one binds their device to
it?

Or, is there no expectation that anybody would attempt to merge such a
pointless patch to begin with?

As we discussed at ELC, putting a real vendor/device in there is also
broken because all instances in the system wil bind to the generic
uio, which is not necessarily what is desired.

I know the arguments against the 'generic-uio' tag, but come on, let's
look at the lesser of two evils here! I call BS on this DTS purity.
