Thanks for the review. I had a few small comments so I'd expect a v2.

I suspect it would look a little weird to add your Reviewed-by to
patch #1 since the way Cong has it you're the direct patch author. :-P
Cong, I suspect you may want to change the tagging on patch #1. I'd
suggest setting yourself as the patch author (git commit --amend
--reset-author), then tag the first patch like this (I put "x-" first
to make it obvious to any bots reading this that these are not tags to
actually apply--remove that when you tag your patch):

x-Co-developed-by: Linus Walleij <linus.walleij@...aro.org>
x-Signed-off-by: Linus Walleij <linus.walleij@...aro.org>
x-Reviewed-by: Linus Walleij <linus.walleij@...aro.org>
x-Signed-off-by: Cong Yang <yangcong5@...qin.corp-partner.google.com>

Also: just as a heads up, Hsin-Yi measured the impact of removing the
"command table" for init and replacing it with a whole pile of direct
function calls. She found that it added over 100K to the driver (!!!).
I believe it went from a 45K driver to a 152K driver. Something to
keep in mind. ;-)
