[RFC PATCH v2 0/7] Introduce IIO interface for Android advanced features

[Daniel Baluta <daniel.baluta@intel.com>]

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.

Changes since v1 (mostly based on comments from Jonathan)

	* introduce TRANSITION event instead of MOTION to better
	represent multilevel state change
	* remove pedometer channel type and steps modifier and replace it 
	with steps channel type
	* squashed together patches introducing channels and associated events
	* introduced IIO_EV_DIR_NONE
	* changed cover letter subject to reflect the changes

Daniel Baluta (4):
  iio: dummy: Add virtual registers for dummy device
  iio: core: Introduce IIO_ACTIVITY channel and TRANSITION event
  iio: dummy: Demonstrate the usage of new channel types
  iio: event_monitor: Add support for new channel types

Irina Tirdea (3):
  iio: core: Introduce IIO_EV_DIR_NONE
  iio: core: Introduce STEPS channel type, ENABLE mask and INSTANCE
    event
  iio: core: Introduce HEIGHT channel type
