Input: dynamically allocate ABS information

2010-08-03T03:30:04+00:00

As all callers are now changed to only use the input_abs_*() access
helpers, switching over to dynamically allocated ABS information is
easy. This reduces size of struct input_dev from 3152 to 1640 on
64 bit architectures.

Input: add static inline accessors for ABS properties

2010-08-03T03:29:50+00:00

In preparation for dynamically allocated ABS axis, introduce a number of
static inline access helpers. This should make the transition less
painful.

Input: introduce MT event slots

2010-07-16T06:52:03+00:00

With the rapidly increasing number of intelligent multi-contact and
multi-user devices, the need to send digested, filtered information
from a set of different sources within the same device is imminent.
This patch adds the concept of slots to the MT protocol. The slots
enumerate a set of identified sources, such that all MT events
can be passed independently and selectively per identified source.

The protocol works like this: Instead of sending a SYN_MT_REPORT
event immediately after the contact data, one sends an ABS_MT_SLOT
event immediately before the contact data. The input core will only
emit events for slots with modified MT events. It is assumed that
the same slot is used for the duration of an initiated contact.

Input: evdev - use driver hint to compute size of event buffer

2010-06-23T20:05:25+00:00

Some devices, in particular MT devices, produce a lot of data.  This
may lead to overflowing of the event queues in evdev driver, which
by default are fairly small. Let the drivers hint the average number
of events per packet generated by the device, and use that information
when computing the buffer size evdev should use for the device.

Input: add Analog Devices AD714x captouch input driver

2010-04-14T06:27:16+00:00

AD7142 and AD7147 are integrated capacitance-to-digital converters
(CDCs) with on-chip environmental calibration for use in systems
requiring a novel user input method. The AD7142 and AD7147 can interface
to external capacitance sensors implementing functions such as buttons,
scrollwheels, sliders, touchpads and so on.

The chips don't restrict the specific usage. Depending on the hardware
connection, one special target board can include one or several these
components. The platform_data for the device's "struct device" holds
these information. The data-struct defined in head file descript the
hardware feature of button/scrollwheel/slider/touchpad components on
target boards, which need be filled in the arch/mach-/.

As the result, the driver is independent of boards. It gets the
components layout from the platform_data, registers related devices,
fullfills the algorithms and state machines for these components and
report related input events to up level.

Input: scancode in get/set_keycodes should be unsigned

2010-03-09T07:19:15+00:00

The HID layer has some scan codes of the form 0xffbc0000 for logitech
devices which do not work if scancode is typed as signed int, so we need
to switch to unsigned it instead. While at it keycode being signed does
not make much sense either.
