> This patch adds support for implementing OMAP3 GPIO as an
> early platform device and adds gpio_init specific to OMAP3
>
> This patch adds device structures for each GPIO device in
> OMAP3 architecture. These strutures are not created in a
> separate *_data.c file because these structures would be
> removed once the driver gets adapted to HWMOD way.

Can we use just a omap specific shift here? Or is the register
ordering different too?
