PWM from userspace in pengutronics

Hi,

How to implement pwm module in latest kernel of pengutronics. If I try to
implement pwm module it gives me ioctl wanrning, ioctl has been remove in
newer kernel. 

As I need to test pwm from userspace using ioctl in latest kernel, what is
the possible way to do it.

Implement a kernel driver that connects internally to the PWM framework and
externally to a misc device to provide IOCTL capabilities.
