Missing PWM driver i.MX25

Hi guys,

I'm using a custom board with i.MX25 processor. This board has a buzzer connected to the PWM1 output, I'd like to make it play some tunes. I am using the linux kernel 2.6.31 and as long as I understood the pwm driver doesn't support my i.MX25. Does anyone know if there is a working driver or where I can find an updated one?

thank you !

I'm in the same situation -- the best thing i have read is to look at the backlight driver for the imx25.  Its controlled by PWM and may be the best place to start.
