Good day.
It looks like Atmel MXT initialisation code on nuri board is broken. I
don't have a datasheet for this touchscreen, but from what I can see in
atmel mxt driver code(drivers/input/touchscreen/atmel_mxt_ts.c), I make
assumption that MXT must have a mandatory MXT_GEN_MESSAGE_T5 object. But
in structure mxt_init_vals (arch/arm/mach-exynos/mach-nuri.c) there are
no configuration data for this object. So mxt_probe() function in Atmel
MXT driver fails during mxt_make_highchg() when it tries to read
registers of GEN_MESSAGE_T5 object.
