Cypress TrueTouch(tm) Standard Product controllers are found in a wide range of embedded devices. This patchset adds support for a variety of TTSP controllers.
The original author of the driver is Kevin McNeely <kev@cypress.com>
Since the hardware is capable of tracking identifiable contacts and the original driver used multi-touch protocol type A (stateless), I've added multi-touch protocol type B (stateful) support.
The driver is composed of a core driver that process the data sent by the contacts (fingers) and two bus specific interface modules (I2C and SPI).
The patchset is composed of:
[PATCH 1/3] Input: cyttsp - Cypress TTSP capacitive multi-touch screen support [PATCH 2/3] Input: cyttsp - add support for Cypress TTSP touchscreen I2C bus interface [PATCH 3/3] Input: cyttsp - add support for Cypress TTSP touchscreen SPI bus interface
