* | | Input: usbtouchscreen - add support for Data Modul EasyTouch TP 72037Armando Visconti2012-03-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Data Modul TP 72037 EasyTouch controller is derived from EGALAX controller and is capable of detecting dual contacts. Packets can be 5 bytes or 10 bytes long, depending whether one or two contacts are detected. Format is same as EGALAX touch controller, but with x and y coordinates inverted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for TI's touchscreen controller for a 4/5/8 wire resistive panel that is directly fed to the ADC. This touchscreen controller will be part of AM335x TI SoC.

* | | Input: add Cypress TTSP capacitive multi-touch screen supportJavier Martinez Canillas2012-01-31
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Cypress TrueTouch(tm) Standard Product controllers are found in a wide range of embedded devices. This driver add support for a variety of TTSP controllers. 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.
