I don't see, how to do that, maybe I did miss the right point.

I digged through the gpio code. There are drivers (gpio-omap) that make sure, that gpio is configured as
input and others that don't care (gpio-mxc / gpio-mxs).

seeing this I posted "gpio: gpio-mxc: make sure gpio is input when request IRQ" on linux-arm-kernel

Global question is: how can we make sure, that the driver that request the IRQ requests also the GPIO (implicit or like in the old platfrom data days explicit)? But thats beyond input devices and my knowledge.
