Hi List, A lot of driver add an extra frequency attribute to allow user to tune triggers frequency from sysfs. This is a lot of code duplication, while most do the exact same thing. I added here two extra fields to struct iio_trigger, frequency and info_mask, which might not be needed at first, but will allow us to add extra parameters more easily. I added as well a callback for info_mask changes in trigger_ops so that drivers can take action when frequency has been changed by the user, but will also be easily extendable.
