Still haven't had a clear feedback from your side on this series (you
commented on a few details, but nothing on the general approach). Could
you please have at a quick look at it, and let me know if I should
adjust the implementation?

Note that I plan to send a new version  addressing comments made by
other maintainers/developers by the end of the week. In the meantime,
could you have a look at the first set of patches (patch 1 to 4 are
completely independent), and apply them if you're happy with it.

As you can see, I now have a lot of patches. This helps in showing the
big picture, but also annoys people when I send this 50+ patchset. So,
if you don't mind, I'd like to drop the changes touching PWM user
drivers (to make them use the atomic API) until we get the other parts
applied.

Thanks,

Boris
