Input: add detailed multi-touch finger data report protocol

2009-04-28T16:36:24+00:00

In order to utilize the full power of the new multi-touch devices, a
way to report detailed finger data to user space is needed. This patch
adds a multi-touch (MT) protocol which allows drivers to report details
for an arbitrary number of fingers.

The driver sends a SYN_MT_REPORT event via the input_mt_sync() function
when a complete finger has been reported.

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.

A set of ABS_MT events with the desired properties are defined. The
events are divided into categories, to allow for partial implementation.
The minimum set consists of ABS_MT_TOUCH_MAJOR, ABS_MT_POSITION_X and
ABS_MT_POSITION_Y, which allows for multiple fingers to be tracked.
If the device supports it, the ABS_MT_WIDTH_MAJOR may be used to provide
the size of the approaching finger. Anisotropy and direction may be
specified with ABS_MT_TOUCH_MINOR, ABS_MT_WIDTH_MINOR and
ABS_MT_ORIENTATION. Devices with more granular information may specify
general shapes as blobs, i.e., as a sequence of rectangular shapes
grouped together by a ABS_MT_BLOB_ID. Finally, the ABS_MT_TOOL_TYPE
may be used to specify whether the touching tool is a finger or a pen.

Input: allow certain EV_ABS events to bypass all filtering

2009-04-28T16:36:16+00:00

With the upcoming multi-touch interface as an example, there is
a need to make certain that all reported events actually get passed
to the event handler. This patch equips the input core with the
ability to bypass all filtering for certain EV_ABS events.

Input: bcm5974 - Add support for the Macbook 5 (Unibody)

2009-04-28T16:35:52+00:00

This patch adds support for the new unibody Macbook, with physically
integrated button and trackpad. Since the integrated button changes
the logic for touch-and-click, a device capability bit mask is now
reported in input_id.version, which can be picked up by user space
via a EVIOCGID call.

Input: bcm5974 - add quad-finger tapping

2009-04-28T16:35:12+00:00

The integrated button on the new unibody Macbooks presents a need to
report explicit four-finger actions. Evidently, the finger pressing
the button is also touching the trackpad, so in order to fully support
three-finger actions, the driver must be able to report four-finger
actions. This patch adds a new button, BTN_TOOL_QUADTAP, which
achieves this.

Input: bcm5974 - prepare for a new trackpad header type

2009-04-28T16:35:03+00:00

The new unibody Macbooks are equipped with an integrated button and
trackpad. The package header of the trackpad interface has changed to
also contain information about the integrated button.  This patch
performs the necessary preparations to allow for the new package
header.

Input: appletouch - fix DMA to/from stack buffer

2009-04-28T16:34:13+00:00

CONFIG_DMA_API_DEBUG spotted an instance of appletouch using
an array on the stack as a DMA buffer for certain hardware.
Change it to use a kmalloc()ed buffer instead.

Here is a fix for this, keeping an open and close, so reducing
the load on the system when the mouse is not in use, and also properly
referencing the maple device buffer following the recent update.
