Thanks for your reply.
The code following the link almost the same as the official kernel source.
what a pity this is not the what i want. I have read a comment says the freescale linux kernel
have the driver fo this device.
However, i could not find the kernel of freescale.

Hello all,
Where could I get the source code of Atmel 641t touchscreen driver?
I searched, no spec document and linux driver source for downloading.

I don't know anything about this device but my search is pointing to:

http://elixir.free-electrons.com/linux/latest/source/drivers/input/touchscreen/atmel_mxt_ts.c

I'll suggest to double check your model number.

Regards,

Amit Kumar
