New code should solely use firmware nodes for the specifics and
not any callbacks.

Ah, we're so close to getting rid of platform data entirely...

Series looks good to me, I'll pick it up next week after the merge
window closes.

Patches look good to me:
Acked-by: Linus Walleij <linus.walleij@linaro.org>
for all patches.

Patch 8 looks HTML on my gmail but I guess the problem
is on my side.

Yours,
Linus Walleij

Thank you!

The entire series has been sent in the same way, it's quite unlikely that
the only patch got mangled while others are okay.

I'm using cmdg - a command-line interface to gmail - and all patches
look fine. Surprisingly, the web interface indeed does mangle patch 8
for some reason.
