[GIT PULL] PWM subsystem for v3.6

[Thierry Reding]

Hi Linus,

The new PWM subsystem aims at collecting all implementations of the
legacy PWM API and to eventually replace it completely. The subsystem
has been in development for over half a year now and many drivers have
already been converted. It has been in linux-next for a couple of weeks
and there have been no major issues so I think it is ready for inclusion
in your tree.

Thanks,
Thierry
