Jingoo Han c838cb3d47 Input: use dev_get_platdata()
Use the wrapper function for retrieving the platform data instead
of accessing dev->platform_data directly. This is a cosmetic change
to make the code simpler and enhance the readability.

Wolfram Sang 16735d022f tree-wide: use reinit_completion instead of INIT_COMPLETION
Use this new function to make code more comprehensible, since we are
reinitialzing the completion, not initializing.

Ferruh Yigit 9664877ed8 Input: cyttsp - I2C driver split into two modules
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.

Dmitry Torokhov aaa60fa7ac Input: cyttsp - remove useless checks in cyttsp_probe()
This fixes reference-before-check problem; there is no reason to check
if caller passed NULL dev or bus_ops as it is done only by bus-specific
drivers which already do the right thing.

Javier Martinez Canillas 4065d1e7b2 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.
