S3C2412 ARM Linux Overview¶
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)
The core clock code provides a set of clocks to the drivers, and allows for source selection and a number of other features.
No support for suspend/resume to RAM in the current system.
No current support for DMA.
There is support for setting the GPIO to input/output/special function and reading or writing to them.
The UART hardware is similar to the S3C2440, and is supported by the s3c2410 driver in the drivers/serial directory.
The NAND hardware is similar to the S3C2440, and is supported by the s3c2410 driver in the drivers/mtd/nand/raw directory.
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.
No current support in the kernel
All the standard, and external interrupt sources are supported. The extra sub-sources are not yet supported.
The RTC hardware is similar to the S3C2410, and is supported by the s3c2410-rtc driver.
The watchdog hardware is the same as the S3C2410, and is supported by the s3c2410_wdt driver.
No current support for the MMC/SD/SDIO block.
The IIC hardware is the same as the S3C2410, and is supported by the i2c-s3c24xx driver.
No current support for the IIS interface.
No current support for the SPI interfaces.
No current support for the on-board ATA block.
