The merge looks fine, but...

This one...

...and this one are drivers/clk and I don't see an ack from the
clock framework maintainer (Mike Turquette) on either.

If Mike is OK for them to go via arm-soc, that should be specified in
the description above (and he should ack them), otherwise they should be
split out and sent via Mike.

A quick glance suggests there are no direct dependencies, so it's
probably best if those changes go through Mike.

Thanks,
