+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

+arch/arm/plat-s3c24xx:
+
+  Files in here are either common to all the s3c24xx family,
+  or are common to only some of them with names to indicate this
+  status. The files that are not common to all are generally named
+  with the initial cpu they support in the series to ensure a short
+  name without any possibility of confusion with newer devices.
+
+  As an example, initially s3c244x would cover s3c2440 and s3c2442, but
+  with the s3c2443 which does not share many of the same drivers in
+  this directory, the name becomes invalid. We stick to s3c2440-<x>
+  to indicate a driver that is s3c2440 and s3c2442 compatible.
+
+  This does mean that to find the status of any given SoC, a number
+  of directories may need to be searched.
