configuring GPIOs it can get its ACPI handle and extract this information
from ACPI tables.
-Currently the kernel is not able to automatically determine from which ACPI
-device it should make the corresponding platform device so we need to add
-the ACPI device explicitly to acpi_platform_device_ids list defined in
-drivers/acpi/acpi_platform.c. This limitation is only for the platform
-devices, SPI and I2C devices are created automatically as described below.

DMA support
~~~~~~~~~~~
DMA controllers enumerated via ACPI should be registered in the system to
- S3C24XX: See Documentation/arm/Samsung-S3C24XX/Overview.txt for full list
- S3C64XX: S3C6400 and S3C6410
- - S5P6440
- - S5PC100
- S5PC110 / S5PV210
A number of configurations are supplied, as there is no current way of
unifying all the SoCs into one kernel.
- s5p6440_defconfig - S5P6440 specific default configuration
- s5pc100_defconfig - S5PC100 specific default configuration
s5pc110_defconfig - S5PC110 specific default configuration
s5pv210_defconfig - S5PV210 specific default configuration
where to simplify the include and dependency issues involved with having
so many different platform directories.
- It was decided to remove plat-s5pc1xx as some of the support was already
- in plat-s5p or plat-samsung, with the S5PC110 support added with S5PV210
- the only user was the S5PC100. The S5PC100 specific items where moved to
- arch/arm/mach-s5pc100.
