Pengutronics BSP - PWM not working !!

Hi,

I just ported Pengutronics BSP to mini2440 board. After that I copied pwm
module from linux-2.6.32-2 to new kernel (3.1), I did some changes
according to new kernel like unlocked_ioctl, sema_init. 

Module compiled successfully and I can load in new board too, but the
problem is after loading module it is not working. I am testing the module
from pwm_test program comes with FriendlyArm BSP.

Can you please guide me in right direction so that I can have working PWM
with newer BSP.

Thank You for your time.

A newer kernel comes with its internal generic PWM framebwork. Maybe the
old driver you are using collides with it. At least the buzzer on the
Mini2440 is driven by a PWM, controlled via the PWM framework. Take a look
into the kernel's "linux-3.6/drivers/input/misc/pwm-beeper.c" file to get
an idea to make use of the generic PWM framework inside a kernel driver.
