Hi Javier,

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.
