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/raw 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.
