Subject: [RFC] Add frequency support in trigger core
Date: Thu, 19 Apr 2012 18:05:36 +0200 [thread overview]
Message-ID: <1334851538-21408-1-git-send-email-maxime.ripard@free-electrons.com> (raw)
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.
Maxime
