Sorry for the late answer, but it took some time to read the patches
again.

Is it a good idea to have to APIs for the same thing in the kernel?
The old API has users whereas the new API has none. How can we migrate
from one API to the other when for example the backlight pwm driver
depends on the old API, SoC level drivers implement the old API, but
the atmel pwm driver is only available for the new API?
