I think so. Many subsystems relatively recently (in the last couple of
years or so) enforced that new drivers have to have official
maintainers. Besides that it's warmly welcome to register existing
drivers in the MAINTAINERS database. I would tell you go ahead and
become a maintainer of AT91 clocks and it will definitely reduce the
burden on Stephan's shoulders.

The idea is that you will send a PR to CCF maintainers instead of
patches, although it's expected that patches appear in the mailing
list beforehand anyway.

Depends a little. For me, a Rev-by from the driver maintainer is enough,
and I'll pick them. That lowers the burden on the drivers maintainer
side. May not work for high volumes of patches, but for I2C this works
enough.

AFAICT in practice it's a mandatory requirement in I²C subsys (in the
past you hadn't accepted a patch from us without a tag from the
maintainer) which makes it equal to sending PR by a maintainer. PR
makes less burden since subsys maintainer don't need to run many tools
or a tool many times to get the pile of patches.

Right. I require a tag from the driver maintainer.

I had driver maintainers who found it difficult to have a public tree to
pull from or forgot how to send properly prepared pull requests. They
were happy to send Rev-by, though. And I am happy with that, too. At
least in I2C, picking up patches is small work compared to the actual
review.
