Re: [PATCH V2 1/3] Input: cyttsp - Cypress TTSP capacitive multi-touch screen support

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.

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.

The original author of the driver is Kevin McNeely [off-list ref]

Since the hardware is capable of tracking identifiable contacts and the
original driver used multi-touch protocol type A (stateless), multi-touch
protocol type B (stateful) support was added by Javier Martinez Canillas.

Changes since v1: Fix issues called out by Dmitry Torokhov
     - Add msleep() delays between retries for read and write operations
     - Change cyttsp_core_init() to receive the IRQ from the client data 
       instead of obtaining from the platform_data

Compared to the staging version you sent earlier, this version seems
to be a step back towards the original version regarding the MT
implementation. Is this the right patch?

Thanks,
Henrik
