SubjectInput: Cypress TTSP device driver
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 <>

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
