Subject: [PATCH v2 04/10] iio: core: Introduce IO_CHAN_INFO_CALIBWEIGHT
Date: Sun, 11 Jan 2015 21:10:10 +0200	[thread overview]
Message-ID: <1421003416-27557-5-git-send-email-irina.tirdea@intel.com> (raw)
In-Reply-To: <1421003416-27557-1-git-send-email-irina.tirdea@intel.com>

Some devices need the weight of the user to compute other
parameters. One of this devices is Freescale's MMA9553L
(http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf)
that needs the weight of the user to compute the number of calories burnt.
