I look at it a bit more: as far as I understand, the TSC2007 driver
works with a "pen down" IRQ, that triggers the tsc2007_work function,
that will poll until the pen is up, and then re-enable the IRQ.
The problem here seems to be that the IRQ isn't triggered everytime the
pend is down on the touchscreen.
