+-------

+ 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

+ Files in here are either common to all the s3c24xx family,

+ This does mean that to find the status of any given SoC, a number
