Hi Dmitry,

We suggest a separate driver for eKTF2127.

Many thanks,
Johnny

The ELAN eKTF2127 driver is written for the ELAN series of 
touchscreencontrollers. This version is especially written for the
eKTF2127 controller. The driver communicates to the controller over i2c.
The additional screen specifications can be read from the devicetree file.
The driver has also the ability to read the screen height and width 
from the controller. When the screen is pressed, a interrupt is generated.
The interrupt wil be handled by a function that request a data string 
from the controller. This string is then modified so that the right 
number of touches and their x and y coordinates are available and 
given to userspace through the input subsystem.

Adding KT. Can eKTF2127 be driven with [modified] elants_i2c driver or we
are better off with separate driver.

Hi Johnny,
Please check Dmitry's touchscreen issue.
