Some devices need the height of the user to compute various parameters. One of this devices is Freescale's MMA9553L (http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf) that needs the height of the user to compute the stride length which is used further to determine distance, speed and activity type.

These changes are needed to support the functionality of a pedometer. A pedometer has two basic functionalities: step counter and step detector. The step counter needs to be enabled and then it will count the steps in its hardware register. Whenever the application needs to check the step count, it will read the step counter register. To support the step counter a new channel type STEPS is added. Since the pedometer needs to be enabled first so that the hardware can count and store the steps, we need a specific ENABLE channel info mask. The step detector will generate an interrupt each time a step is detected. To support this functionality we add a new event type INSTANCE. For more information on the Android requirements for step counter and step detector see: http://source.android.com/devices/sensors/composite_sensors.html#counter and http://source.android.com/devices/sensors/composite_sensors.html#detector. A device that has the pedometer functionality this interface needs to support is Freescale's MMA9553L: http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdfSigned-off-by: Irina Tirdea <irina.tirdea@intel.com> Signed-off-by: Daniel Baluta <daniel.baluta@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

This channel will be used for exposing information about activity composite sensors. Activities supported so far: * running * jogging * walking * still THRESHOLD event is used to signal a change in the activity state. We associate a confidence interval for each activity expressed as a percentage from 0 to 100. * 0, means the sensor IS NOT reporting that activity. * 100, means the sensor IS reporting that activity. Users of this interface have two possible means to gather information about the ongoing activities. 1. Event based, via event file descriptor * sensor may report an event when ENTERING an activity or LEAVING an activity based on a threshold value. * drivers will wake up applications waiting data on the event fd 2. Polling, by reading the sysfs associated attribute files: * /sys/bus/iio/devices/iio:device0/in_activity_running_input expressed as percentage confidence value from 0 to 100. This will offer an interface for Android significant motion composite sensor defined here: http://source.android.com/devices/sensors/composite_sensors.html Activities listed above are supported by Freescale's MMA9553 sensor: http://freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdfSigned-off-by: Irina Tirdea <irina.tirdea@intel.com> Signed-off-by: Daniel Baluta <daniel.baluta@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

We need a way to store events generated by iio_dummy_evgen module, in order to correctly process IRQs in iio_simple_dummy_events. For the moment, we add two registers: * id_reg - ID register, stores the source of the event * id_data - DATA register, stores the type of the event e.g echo 4 > /sys/bus/iio/devices/iio_evgen/poke2 id_reg 0x02, id_data 0x04 This means, event of type 4 was generated by fake device 2. We currently use a hardcoded mapping of virtual events to IIO events.

The Onda v975w tablet contains an accelerometer that's advertised over ACPI as SMO8500. This device is however a KXCJ9 accelerometer as can be seen in the Windows driver's INF file, and from the etching on the chipset ("KXCJ9 41566 0414"). This patch also removes the attempt to get the IRQ for the "data ready" signal, as it does not seem to be supported by this device on this platform.

Now that Comedi has the structures in place to support setting the current "read" and/or "write" subdevice on a per-file object basis, add new ioctls to set them. The newly chosen "read" ("write") subdevice needs to support "read" ("write") commands, and the file cannot be busy handling a "read" ("write") command on the previous subdevice (if any).

Ian Abbott authored
Comedi devices may have several subdevices that support "read" and/or "write" asynchronous commands that use the "read" or "write" file operations for data transfer. The low-level Comedi drivers may nominate a default "read" subdevice and/or a default "write" subdevice, but it may have other subdevices that support asynchronous commands. The Comedi core provides a somewhat clunky mechanism to provide access to the asynchronous command support of the non-default subdevices. When a low-level device is "attached" to a core Comedi device, it dynamically allocates a minor device number for each of the subdevices that support asynchrounous commands and associates them with files created in SysFS named "comediX_subdY", where "X" is the minor device number of the main comedi device, and "Y" is the subdevice number. An application can open these subdevice-specific files and they behave like the regular "comediX" files except that the "read" and/or "write" subdevice may be different to the default chosen by the low-level driver. This patch adds a layer of indirection between the file object and the comedi device object to allow the current "read" and/or "write" subdevice to be altered after opening the Comedi device, on a per-file object basis. The advantage is that an application only needs to open the main Comedi device file and can then choose which subdevice it wants to "read" or "write". The main Comedi device file can be opened more than once, and each file object can choose the "read" and "write" subdevices independently. The new `struct comedi_file` is created on "open" and freed on "release". It includes pointers to the main Comedi device structure, and to the current "read" and "write" subdevice structures (which may be NULL). It also has information to keep track of when a low-level device has been attached or detached since the previous time the file object was used. In that case, the current "read" and "write" subdevices in the `struct comedi_file` will be changed to the new defaults (or set to NULL). (The change to new defaults is done by `comedi_file_reset()`. The checking for attach/detach is done by `comedi_file_check()` which will call `comedi_file_reset()` if there have been any attach/detach operations since the previous call.) A subsequent patch will add the ioctls to change the current "read" and "write" subdevices.
