Thanks, I didn't see those come up in the get_maintainers output.
I had a longer question related to this patch progression -- if I am
moving the aspeed gpio driver to the soc folder, the soc tree may have
the soc/aspeed folder in their next, but the gpio tree wouldn't
necessarily. I know the branches sync up when things are merged at
the top, but I wasn't sure if there was another mechanism for this?
