[PATCH] arm pxa: remove "direction input" forcing for IRQ GPIOs

[giometti@linux.it (Rodolfo Giometti)]

PXA CPUs may use their GPIOs as IRQ lines even if they are selected as
outputs (see for example figure 24-1 into PXA27x Processor Family
Developer's Manual). So forcing GPIOs IRQ lines as inputs is not
correct.

Programmers should set up GPIOs direction according to their usage and
the function pxa_gpio_irq_type() should simply enable the IRQ
detection.
