Kernel driver for CMA3000-D0x
============================
Supported chips:
* VTI CMA3000-D0x
Datasheet:
CMA3000-D0X Product Family Specification 8281000A.02.pdf
<http://www.vti.fi/en/>
Author: Hemanth V <hemanthv@ti.com>
Description
-----------
CMA3000 Tri-axis accelerometer supports Motion detect, Measurement and
Free fall modes.
Motion Detect Mode: Its the low power mode where interrupts are generated only
when motion exceeds the defined thresholds.
Measurement Mode: This mode is used to read the acceleration data on X,Y,Z
axis and supports 400, 100, 40 Hz sample frequency.
Free fall Mode: This mode is intended to save system resources.
Threshold values: Chip supports defining threshold values for above modes
which includes time and g value. Refer product specifications for more details.
CMA3000 chip supports mutually exclusive I2C and SPI interfaces for
communication, currently the driver supports I2C based communication only.
Initial configuration for bus mode is set in non volatile memory and can later
be modified through bus interface command.
Driver reports acceleration data through input subsystem. It generates ABS_MISC
event with value 1 when free fall is detected.
Platform data need to be configured for initial default values.

indicate the distance between the contact and the surface.
In addition to the MAJOR parameters, the oval shape of the contact can be
described by adding the MINOR parameters, such that MAJOR and MINOR are the
major and minor axis of an ellipse. Finally, the orientation of the oval
shape can be describe with the ORIENTATION parameter.
For type A devices, further specification of the touch shape is possible
via ABS_MT_BLOB_ID.
The ABS_MT_TOOL_TYPE may be used to specify whether the touching tool is a
contact or a pen or something else. Devices with more granular information
may specify general shapes as blobs, i.e., as a sequence of rectangular
shapes grouped together by an ABS_MT_BLOB_ID. Finally, for the few devices
that currently support it, the ABS_MT_TRACKING_ID event may be used to
report contact tracking from hardware [5].

the contact. This is a low-level anonymous grouping for type A devices, and

devices do not have blob capability, so drivers can safely omit this event.
ABS_MT_TRACKING_ID
The TRACKING_ID identifies an initiated contact throughout its life cycle
[5]. This event is mandatory for type B devices. The value range of the
TRACKING_ID should be large enough to ensure unique identification of a
contact maintained over an extended period of time.

-----
In order to stay compatible with existing applications, the data
reported in a finger packet must not be recognized as single-touch
events. In addition, all finger data must bypass input filtering,
since subsequent events of the same type refer to different fingers.

For type A devices, all finger data bypasses input filtering, since

The first kernel driver to utilize the MT protocol is the bcm5974 driver,
where examples can be found.
For example usage of the type A protocol, see the bcm5974 driver. For
example usage of the type B protocol, see the hid-egalax driver.
