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. + + +Document Author +--------------- + +Ben Dooks, Copyright 2006 Simtec Electronics -- cgit v1.2.3
