S3C2412 ARM Linux Overview
==========================
Introduction
------------
The S3C2412 is part of the S3C24XX range of ARM9 System-on-Chip CPUs
from Samsung. This part has an ARM926-EJS core, capable of running up
to 266MHz (see data-sheet for more information)
Clock
-----
The core clock code provides a set of clocks to the drivers, and allows
for source selection and a number of other features.
Power
-----
No support for suspend/resume to RAM in the current system.
DMA
---
No current support for DMA.
GPIO
----
There is support for setting the GPIO to input/output/special function
and reading or writing to them.
UART
----
The UART hardware is similar to the S3C2440, and is supported by the
s3c2410 driver in the drivers/serial directory.
NAND
----
The NAND hardware is similar to the S3C2440, and is supported by the
s3c2410 driver in the drivers/mtd/nand directory.
USB Host
--------
The USB hardware is similar to the S3C2410, with extended clock source
control. The OHCI portion is supported by the ohci-s3c2410 driver, and
the clock control selection is supported by the core clock code.
USB Device
----------
No current support in the kernel
IRQs
----
All the standard, and external interrupt sources are supported. The
extra sub-sources are not yet supported.
RTC
---
The RTC hardware is similar to the S3C2410, and is supported by the
s3c2410-rtc driver.
Watchdog
--------
The watchdog hardware is the same as the S3C2410, and is supported by
the s3c2410_wdt driver.
MMC/SD/SDIO
-----------
No current support for the MMC/SD/SDIO block.
IIC
---
The IIC hardware is the same as the S3C2410, and is supported by the
i2c-s3c24xx driver.
IIS
---
No current support for the IIS interface.
SPI
---
No current support for the SPI interfaces.
ATA
---
No current support for the on-board ATA block.
