iio: core: Introduce DISTANCE channel type
Some devices export an estimation of the distance the user has covered since the last reset. One of this devices is Freescale's MMA9553L (http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf) that computes the distance based on the stride length and step rate. Introduce a new channel type DISTANCE to export these values. Signed-off-by: Irina Tirdea <irina.tirdea@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
