Hi Pawel
Thanks for adding the mvebu Maintainers to the list of recipients.
One more process point. It would be normal to set the To: to whoever
you think should actually accept this patch. There are a lot of
Maintainers listed in Cc: so actually pointing a finger at somebody
can help.
Gregory will be the person to actually take this patch.

Thanks for adding a comment. So you need something like a PWM driving
it? Have you tried playing with drivers/input/misc/pwm-beeper.c ?
Some of the mvebu family have a simple PWM functionality as part of
the GPIO controller. I don't remember if kirkwood has this.
