GPIOLIB
-------

With the event of the GPIOLIB in drivers/gpio, support for some
of the GPIO functions such as reading and writing a pin will
be removed in favour of this common access method.

Once all the extant drivers have been converted, the functions
listed below will be removed (they may be marked as __deprecated
in the near future).

- s3c2410_gpio_getpin
- s3c2410_gpio_setpin
