As Chen-Yu mentioned, I talked to Stephen about this at Linux Plumbers
in person last December. I'm interested, and given the importance of the
subsystem, I think we actually need even more people to help spread the
load for a healthy ecosystem.

Since there's a fair bit of odds and ends that get missed, I tried to
start gathering things up for v7.1rc1:

https://lore.kernel.org/linux-clk/abLV9vjYxXsKciHW@redhat.com/

But I never got a response outside of Andy's response. I don't know if
Stephen didn't like things that were in it, or if he didn't like that I
gathered up patches from other folks. I just don't know.

That's why during the next merge window I just brought missing patches
in the pull to Linus:

https://lore.kernel.org/linux-clk/aeeHSrZmAqE4ugXY@redhat.com/

... and again during the last merge window:

https://lore.kernel.org/linux-clk/aj1NUYRrD30ctAbt@redhat.com/

Next week I plan to post another pull for new material posted this
development cycle for things that I feel are ready, and where they won't
be sent in by someone else via a different pull.

I'm not trying to take anything from anyone, and I'm not trying to make
anyone mad. I'm just trying to step up and help make the situation in
the clk subsystem better.

I'm also trying to separately address some long-standing issues in the
framework:

    v3: clk: implement sync_state support
    https://lore.kernel.org/linux-clk/20260626-clk-sync-state-v1-0-4156d8196dc8@redhat.com/

    v8: clk: add support for v1 / v2 clock rate negotiation and kunit tests
    https://lore.kernel.org/linux-clk/20260327-clk-scaling-v8-0-86cd0aba3c5f@redhat.com/

I also removed the round_rate() op, which involved 200+ patches across
the tree.

To help with review, I also think that we should enable Sashiko reviews
to the mainglist like some other subsystems currently have enabled.
