2013-07-06Input: cyttsp4 - use 16bit address for I2C/SPI communicationFerruh Yigit
In TSG4, register map is 512bytes long and to access all of it, one bit from address byte is used (which bit to use differs for I2C and SPI); Since common code used for TSG3 and TSG4 for I2C, this parameter wrongly used as u8. TSG3 does not access beyond 255 bytes but TSG4 may.

2013-06-30Input: cyttsp - I2C driver split into two modulesFerruh Yigit
Existing I2C code is for TrueTouch Gen3 devices TrueTouch Gen4 device is using same protocol, will split driver into two pieces to use common code with both drivers. Read/Write functions parameter list modified, since shared code will be used by two separate drivers and these drivers are not sharing same structs, parameters updated to use common structures.

2013-06-05Input: cyttsp - fix swapped mfg_stat and mfg_cmd registersMatthias Kaehlcke
The command and status register in the driver were swapped with respect to the order specified in the datasheet (CY8CTMA140). Confirmed with Cypress that the order in the datasheet is correct.

2012-01-31Input: add Cypress TTSP capacitive multi-touch screen supportJavier Martinez Canillas
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.
