Hi Dmitry,

Currently the driver atmel_mxt_ts.c supports 3 different models of
atmel touch controller:

1. qt602240_ts
2. atmel_mxt_ts   (which is for mxt1386)
3. mXT224

Confirmed with atmel side that qt602240_ts is actually an alias for
mxt224, and mxt224
follows the same protocol guide with mxt1386, which means it will
report the pressure
information the same way as mxt1386.
