I should also add that Allwinner not only talked to us already, but also
expressed interest in doing actual modern kernel development (like using
"recently" introduced kernel frameworks, like the clk framework).

I've received patches from them already for private reviews, they began
to show up on the kernel mailing lists, they asked to be CCed on the
patches I send upstream, they're even the one that reached out to me
when the early support for their chips was released. So, like Olof said,
they aren't in a vacuum, they are very aware of the mainline kernel and
speak a decent english.

So yes, Allwinner has an evil vendor tree (c), with a solution similar yet
inferior (because not generic enough) to the device tree, but they show
interest on going down the mainline road.
