Subject: [PATCH 07/11] iio: sensors-core: st: Allow full-scale to be an optional feature
Date: Wed, 4 Sep 2013 10:31:39 +0100 [thread overview]
Message-ID: <1378287103-21765-8-git-send-email-lee.jones@linaro.org> (raw)
In-Reply-To: <1378287103-21765-1-git-send-email-lee.jones@linaro.org>
Some chips either don't support it or fail to provide adequate documentation,
so sometimes it's impossible to enable the feature even if it is supported.
