What other purposes does it serve? I'd expect you need it during new
board bringup.
Yes, during board bringup it's extremely useful. We have implemented

you can get that from dmesg output
(it's in T6 messages).
You can try the mxt-app tool without the driver changes via i2c-dev, just
run it like "mxt-app -d2 -a4b" (for /dev/i2c-2, addr 4b).

maXTouch chips and firmware versions have different sizes of message buffer
depending on the objects used, therefore it can't be hardcoded in the driver.
Allocate a buffer on probe instead.

The delay before the chip can be accessed after reset varies between different
chips in maXTouch family. Waiting for 200ms and then monitoring the CHG (chip
is ready when the line is low) is guaranteed to work with all chips.

The matrix size is only used to print out a debug message, and results in some
rather confusing code to re-read it if the device configuration is updated. So
don't print it out.

Atmel supplies firmware files in ASCII HEX format (.enc) which must be
converted before they can be loaded by kernel driver. Try to detect the error
and print a friendly error message rather than feeding junk to the bootloader.

device integration more error-prone because it duplicates information set
elsewhere. In addition, different versions of maXTouch chips may have these
values in different places or may not even have them at all.
