| 1 | S3C2412 ARM Linux Overview | ||
| 2 | ========================== | ||
| 3 | |||
| 4 | Introduction | ||
| 5 | ------------ | ||
| 6 | |||
| 7 | The S3C2412 is part of the S3C24XX range of ARM9 System-on-Chip CPUs | ||
| 8 | from Samsung. This part has an ARM926-EJS core, capable of running up | ||
| 9 | to 266MHz (see data-sheet for more information) | ||
| 10 | |||
| 11 | |||
| 12 | Clock | ||
| 13 | ----- | ||
| 14 | |||
| 15 | The core clock code provides a set of clocks to the drivers, and allows | ||
| 16 | for source selection and a number of other features. | ||
| 17 | |||
| 18 | |||
| 19 | Power | ||
| 20 | ----- | ||
| 21 | |||
| 22 | No support for suspend/resume to RAM in the current system. | ||

| 36 | |||
| 37 | |||
| 38 | UART | ||
| 39 | ---- | ||
| 40 | |||
| 41 | The UART hardware is similar to the S3C2440, and is supported by the | ||
| 42 | s3c2410 driver in the drivers/serial directory. | ||
| 43 | |||
| 44 | |||
| 45 | NAND | ||
| 46 | ---- | ||
| 47 | |||
| 48 | The NAND hardware is similar to the S3C2440, and is supported by the | ||
| 49 | s3c2410 driver in the drivers/mtd/nand directory. | ||
| 50 | |||
| 51 | |||
| 52 | USB Host | ||
| 53 | -------- | ||
| 54 | |||
| 55 | The USB hardware is similar to the S3C2410, with extended clock source | ||
| 56 | control. The OHCI portion is supported by the ohci-s3c2410 driver, and | ||
| 57 | the clock control selection is supported by the core clock code. | ||
| 58 | |||
| 59 | |||
| 60 | USB Device | ||
| 61 | ---------- | ||
| 62 | |||
| 63 | No current support in the kernel | ||
| 64 | |||
| 65 | |||
| 66 | IRQs | ||
| 67 | ---- | ||
| 68 | |||
| 69 | All the standard, and external interrupt sources are supported. The | ||
| 70 | extra sub-sources are not yet supported. | ||
| 71 | |||
| 72 | |||
| 73 | RTC | ||
| 74 | --- | ||
| 75 | |||
| 76 | The RTC hardware is similar to the S3C2410, and is supported by the | ||
| 77 | s3c2410-rtc driver. | ||
| 78 | |||
| 79 | |||
| 80 | Watchdog | ||
| 81 | -------- | ||
| 82 | |||
| 83 | The watchdog harware is the same as the S3C2410, and is supported by | ||
| 84 | the s3c2410_wdt driver. | ||
| 85 | |||
| 86 | |||
| 87 | MMC/SD/SDIO | ||
| 88 | ----------- | ||
| 89 | |||
| 90 | No current support for the MMC/SD/SDIO block. | ||
| 91 | |||
| 92 | IIC | ||
| 93 | --- | ||
| 94 | |||
| 95 | The IIC hardware is the same as the S3C2410, and is supported by the | ||
| 96 | i2c-s3c24xx driver. | ||
| 97 | |||
| 98 | |||
| 99 | IIS | ||
| 100 | --- | ||
