[GIT PULL] PWM subsystem

[Thierry Reding]

Hi Stephen,

The PWM subsystem patches have gone through a number of versions now and
all outstanding issues have been resolved. I believe that the subsystem
is ready for broader testing in linux-next. If all goes well I plan to
submit it to Linus during the 3.6 merge window.

I am not aware of any dependencies in linux-next. The two patches that
don't touch the PWM subsystem itself are OF related and have been acked
by Rob Herring who prefers that I take them through the PWM tree.

Please contact me if there are any issues with the tree.

The following changes since commit cfaf025112d3856637ff34a767ef785ef5cf2ca9:
