I have to resend the mail, so the kernel list rejected it. I had HTML
enabled in the MUA by mistake. Sorry for the inconvenience!
Thierry, thank you for this very complete review!

From: Lars Poeschel
This adds a simple sysfs interface to the pwm subsystem. It is
heavily inspired by the gpio sysfs interface.
/sys/class/pwm
/export ... asks the kernel to export a PWM to userspace
/unexport ... to return a PWM to the kernel
