		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 harware 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.
