* Input: matrix-keymap - wire up device tree supportDmitry Torokhov2012-05-101-18/+0
| | | | | | | | | | | When platform keymap is not supplied to matrix_keypad_build_keymap() and device tree support is enabled, try locating specified property and load keymap from it. If property name is not defined, try using "linux,keymap". Based on earlier patch by Viresh Kumar <viresh.kumar@st.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

* Input: Add Synaptics NavPoint (PXA27x SSP/SPI) driverPaul Parsons2012-05-101-0/+12
| | | | | | | | | | | This driver adds support for the Synaptics NavPoint touchpad connected to a PXA27x SSP port in SPI slave mode. The device emulates a mouse; a tap or tap-and-a-half drag gesture emulates the left mouse button. For example, use the xf86-input-evdev driver for an X pointing device.

| | | | | | | | | | This driver adds support for the keypad part of the LM8333 and is prepared for possible GPIO/PWM drivers. Note that this is not a MFD because you cannot disable the keypad functionality which, thus, has to be handled by the core anyhow.

* Input: kxtj9 - who_am_i check value and initial data rate fixesChristopher Hudson2012-03-161-10/+1
| | | | | | | | | | | | | | | | | | Several fixes based on customer feedback: * WHO_AM_I value has changed since preliminary parts used for initial testing; * Output of le16_to_cpu must be saved to memory before shifting to preserve sign; * Initial data rate was not extracted from data control register init. This was causing the initial data rate to be set to maximum until it was changed. To fix this problem, it made more sense to specify initial data rate and extract the register mask from that.

Since the hardware is capable of tracking identifiable contacts, multi-touch protocol type B (stateful) is used to report contact information. The driver is composed of a core driver that process the data sent by the contacts and a set of bus specific interface modules. This patch adds the base core TTSP driver.

| | | | | | | | | | | | | | | | | | Some displays from AUO have a so called in-cell touchscreen, meaning it is built directly into the display unit. Touchdata is gathered through PIXCIR Tango-ICs and processed in an Atmel ATmega168P with custom firmware. Communication between the host system and ATmega is done via I2C. Devices using this touch solution include the Dell Streak5 and the family of Qisda ebook readers. The driver reports single- and multi-touch events including touch area values.

| | | | | | | | | | | | | | | | | There exist tilt switches that simply report their tilt-state via some gpios. The number and orientation of their axes can vary depending on the switch used and the build of the device. Also two or more one-axis switches could be combined to provide multi-dimensional orientation. One example of a device using such a switch is the family of Qisda ebook readers, where the switch provides information about the landscape / portrait orientation of the device.

| | | | | | | | | | | | | | | | The ADP5585 family keypad decoder and IO expander is similar to the ADP5589, however it features less IO pins, and lacks hardware assisted key-lock functionality. Unfortunately the register addresses are different, as well as the event codes and bit organization within the port related registers. Move ADP5589 Register defines from the header file into the main source file. Add new defines while making sure we don't break existing platform_data.
