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).

The Samsung S3C24XX range of ARM9 System-on-Chip CPUs are supported
by the 's3c2410' architecture of ARM Linux. Currently the S3C2410,
S3C2412, S3C2413, S3C2440 and S3C2442 devices are supported.
S3C2412, S3C2413, S3C2440, S3C2442 and S3C2443 devices are supported.
Support for the S3C2400 and S3C24A0 series are in progress.
Support for the S3C2400 series is in progress.

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.

SD/MMC
------
The SD/MMC hardware pre S3C2443 is supported in the current
kernel, the driver is drivers/mmc/host/s3cmci.c and supports
1 and 4 bit SD or MMC cards.
The SDIO behaviour of this driver has not been fully tested. There is no
current support for hardware SDIO interrupts.

The core contains support for manipulating the GPIO, see the
documentation in GPIO.txt in the same directory as this file.
Newer kernels carry GPIOLIB, and support is being moved towards
this with some of the older support in line to be removed.
