The GPIO is set up as an IRQ, so request it as non-exclusive. Otherwise the
probe fails on Nokia 770 with:
ads7846 spi2.0: failed to request pendown GPIO
ads7846: probe of spi2.0 failed with error -16
Also the polarity is wrong. Fix it.

Do we need to have this knowledge in the driver or can it be handled
in GPIO subsystem or affected board support? Requesting a GPIO with "in"
direction when it is also an interrupt source should be pretty common.
Thanks.
