this is an update on your touchscreen driver on the S3C6410:
after some debugging I found out that the S3C6410's touchscreen differs
with the S3C24XX in that it has:
a) 12-bit ADC support (haven't looked at that atm)
b) additional registers used for clearing ADC and TS interrupts
Due to b), the FIFO constantly got filled with up/down messages as the
interrupt was never cleared.
I've added/hacked support for this in my tree currently, but am waiting
till your driver get in upstream
to rebase my tree and try merging my changes.
