- 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.
