First off, this series looks fine to me. Please add,

Acked-by: Michael Turquette <mturquette at baylibre.com>

Secondly, it seems the AmLogic clock drivers have mostly calmed down and
things are in the "add new clocks when we need them" phase, which is
nice. Since you and Neil are doing a lot of this work, might I suggest
that you both start collecting patches for the AmLogic/meson clock
drivers begin submitting pull requests to Stephen and myself?

As usual the rules are the same as always: all patches in the PR must
first be posted for review on the list. PRs should correspond to signed
tags. Stephen and I might ignore PRs sent after -rc4, and will
definitely ignore PRs sent after -rc6 since we want some stabilization
time before the merge window. Base your branch on -rc1, not on clk-next.

Also feel free to submit a patch to MAINTAINERS with either one or both
of you maintaining the meson clk stuff, assuming that you're OK to
review all of those patches and collect them into a PR.

Thoughts?

If it sounds good to you then I suggest grabbing the clk-meson branch
from the clk tree and using that as a baseline for your first PR. In the
future you'll just Linus' -rc1, but I have already created a branch for
this cycle. You can apply these 8 patches with my Ack and send a PR by
-rc6 (possibly with other stuff collected from Martin, etc).

Thanks,
Mike
