Mostly because I want to write a different driver that uses the PWM DMA interface on the Pi but it seems wrong to do this without having a common PWM_DMA interface Gordon -- To unsubscribe from this list: send the line "unsubscribe linux-pwm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
