Well, since this series is not merged yet, I would suggest to refrain from
merging this version.
By the way of my other works, I have found that the case of samsung
pwm/timer is a bit more complex than it initially seemed and it has to be
done in a different way, to coordinate two separate drivers accessing the
same hardware (samsung-time and pmw-samsung).
I'm currently working on next version, which is going to rework the pwm-
samsung driver as well.
Best regards,
Tomasz
