I ended up applying the series without the clk driver now, please see

https://git.kernel.org/pub/scm/linux/kernel/git/soc/soc.git/commit/?h=arm/newsoc&id=7cb7b8fe63393d77

No need to resend the series any more, please just work with
the clk maintainers to get that driver included through their tree.

If there are any issues with the patches that I merged, it's best
to send bugfix patches that can be applied on top of the branch
listed above, or a pull request based on that commit.

For new features to be merged in a later release, e.g. patches to
add device tree nodes for other on-chip components, or additional
dts files, please base them on the coming -rc1 release when that
is out.
