This patchset introduces a new interface for supporting some of the composite sensors in Android [1]. First supported sensors are activity and pedometer.
This is a follow up of the discussion about adding new channels to IIO initiated some time ago on IIO list [2]. A device that has the activity/pedometer functionality is Freescale's MMA9553L ([3]). Because we don't have yet the hardware, to demonstrate these new channels we update iio_dummy kernel module and iio_event_monitor test program. We want to get an early feedback about extending the IIO interface in the correct direction.
