Thomas and Arnd cc-ed on the whole series, as this could be consolidation material.

Very nice stuff. Should we take this all in one branch in the arm-soc tree, pending Acks from the subarch maintainers?

We could also push it through the individual subarch branches, but my feeling is that would be more work.

If this is the direction to go, then there are a lot of other timers that can be moved besides just local timers. But Russell didn't really like the shmobile patches for early platform devices which this relies on. So we should get agreement on the small bit of infrastructure needed first, then start moving individual timers.

I'm open to suggestions. Should the early platform infrastructure be flagged as unsuitable, I'd be happy to switch to something else, as long as it is minimal, and does not create another ARM-specific API (been there, done that...).

Also, device tree support for early platform devices would be useful for this.

Indeed.
