Input: add Cypress TTSP capacitive multi-touch screen support 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.
