+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

The GPIO management functions are defined in the hardware

A useful amount of documentation can be found in the hardware
