Subject: [PATCH v2 01/10] iio: core: Introduce ENERGY channel type
Date: Sun, 11 Jan 2015 21:10:07 +0200	[thread overview]
Message-ID: <1421003416-27557-2-git-send-email-irina.tirdea@intel.com> (raw)
In-Reply-To: <1421003416-27557-1-git-send-email-irina.tirdea@intel.com>

Human activity sensors report the energy burnt by the user.
One of this devices is Freescale's MMA9553L
(http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf)
that computes the number of calories based on weight and step rate.

Introduce a new channel type ENERGY to export these values.
