From d37f6836fa285882450e28d1cbc5a9b624911e7e Mon Sep 17 00:00:00 2001 From: Irina Tirdea Date: Sun, 11 Jan 2015 21:10:10 +0200 Subject: [PATCH] iio: core: Introduce IIO_CHAN_INFO_CALIBWEIGHT 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.
