Subject: [PATCH] Input: cyttsp - do not force interrupt trigger

Instead of forcing interrupt trigger to be "falling edge" let's rely on the
platform to set it up according to how it is set up on a given board based
on data in device tree or ACPI tables.

Linus, Ferruh's email has been bouncing for ages, it looks like you have
the hardware and you are already looking over another Cypress touch
controller, mind if I put you down as a maintainer for this one as well?
