Sorry for the delay; I have not had the time to focus on this as I would
like to. I'm happy with patches 1-4, but from patch 5 onwards, there's
one change I'd like to see.

I'd prefer that mmio timer frame rame N was always stored at
arch_timer_mem::frame[N], rather than arch_timer_mem::frame[] being in
an arbitrary order. That will make arch_timer_mem_frame::frame_nr
redundant.

To allow arch_timer_mem::frame[] this to be sparse, I'm happy to have a
bool arch_timer_mem_frame::valid field that we set when probing each
frame. Then we don't need arch_timer_mem::num_frames.

This will make iterating over the frames far less confusing, and makes
it simple to detect when a frame number is erroneously reused.

Otherwise, I'm largely happy to pick the rest and apply any fixups
myself.

Great thanks for your feedback!
I will follow your suggestion to improve my patches, then post it in a day.

Thanks, that is much appreciated.

So I will rebase my patchset on arch-timer/gtdt branch of your REPO
https://git.kernel.org/pub/scm/linux/kernel/git/mark/linux.git/log/?h=arch-timer/gtdt

Yes please! The current HEAD should be:

ebbfe8889cffa12f ("clocksource: arm_arch_timer: move arch_timer_needs_of_probing into DT init call").

Thanks,
Mark.
