Can anyone tell me about PWM in Linux 3.12+ Please?

I got PWM working in Ubuntu 13.10 Linux 3.8, but the same API (pwm_test) is missing in Linux 3.12+
And I can’t seem to find anything with google.

Can anyone tell me how its supposed to work in Linux 3.12+

Please help!


This is a very, very nice question.

I try to see the answer too.


I’ve tried to build pwm_test under 3.12 and it works seamless BUT the dts_common file is hesvy changed so I didn’t figure how to match the old overlay with the new kernel… after that I gave up and went back to 3.8.13.

I’m also interested in other experience
