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. Document Author --------------- Ben Dooks, Copyright 2006 Simtec Electronics
