This seems to have been broken since 2010, so obviously noone actually

irq_to_gpio isn't available on most platforms today, so the driver
will need some rework by someone who has hardware access and can test
(to make sure that, for example, switching to level interrupts and just
keep taking them while there's more to process works).
I guess it could just be scheduled for removal, but let's start with
marking it CONFIG_BROKEN.
Well, it probably works quite well on arches that do have irq_to_gpio(),
let's ask Daniel and Sven if they still have this hardware and if they
can try the patch below that implements what you suggested.
This hardware is still in use and we also still follow kernel
development and try to update our customer devices to recent kernel
versions regularly. Currently we are at 3.1.10 and the touchscreen works
well with that. I'll try to update to a more recent kernel next week and
will try your patch.
Regards, Sven
