asm/io.h may not be included implicitly, causing a rare
randconfig build error:

I am thinking a bit about the future of this driver. Isn't it more
reasonable to just make a hrtimer-driven PWM and use the existing
PWM userspace ABI and timer framework in Linux for this?
Not that there is a generic timer-driven PWM but ... that is
essentially what this driver is.

Yours,
Linus Walleij

Please ignore, this does not apply to mainline and is probably only needed
on top of another patch that I will submit in the future.
