[RFC v2] gpio/omap: auto-setup a GPIO when used as an IRQ

2013-09-24 Thread Javier Martinez Canillas
The OMAP GPIO controller HW requires a pin to be configured in GPIO input mode in order to operate as an interrupt input. Since drivers should not be aware of whether an interrupt pin is also a GPIO or not, the HW should be fully configured/enabled as an IRQ if a driver solely uses IRQ APIs such as
