With your review/ack on the driver, I'd be happy to take it via the
amlogic tree as there shouldn't be any conflicts with your tree.

I am ok with the driver, but I don't understand how it helps going via
amlogic tree. I would like to send a pull request every release ;)

cheers.

That's fine with me too.  I offered tot take int just in case you had
already sent pull requests for this cycle, and also since I'll take
the DT changes through arm-soc.

Either way is fine with me. Just let me know.

Thanks,

Kevin

This revision came after rc2, so it wasn't included. I will queue
patch-1 & 2 for next release, and you the patch-3.
