* Javier Martinez Canillas [off-list ref] [130924 17:45]:

The GPIO OMAP controller pins can be used as IRQ and GPIO
independently so is necessary to keep track GPIO pins and
IRQ lines usage separately to make sure that the bank will
always be enabled while being used.

Also move gpio_is_input() definition in preparation for the
next patch that setups the controller's irq_chip driver when
a caller requests an interrupt line.

Thanks both of these look good to me for fixing
the regression:
