  2. S3C2412 ARM Linux Overview
  3. ==========================
  4. Introduction
  5. ------------
  6. The S3C2412 is part of the S3C24XX range of ARM9 System-on-Chip CPUs
  7. from Samsung. This part has an ARM926-EJS core, capable of running up
  8. to 266MHz (see data-sheet for more information)
  9. Clock
  10. -----
  11. The core clock code provides a set of clocks to the drivers, and allows
  12. for source selection and a number of other features.
  13. Power
  14. -----
  15. No support for suspend/resume to RAM in the current system.
  16. DMA
  17. ---
  18. No current support for DMA.
  19. GPIO
  20. ----
  21. There is support for setting the GPIO to input/output/special function
  22. and reading or writing to them.
  23. UART
  24. ----
  25. The UART hardware is similar to the S3C2440, and is supported by the
  26. s3c2410 driver in the drivers/serial directory.
  27. NAND
  28. ----
  29. The NAND hardware is similar to the S3C2440, and is supported by the
  30. s3c2410 driver in the drivers/mtd/nand/raw directory.
  31. USB Host
  32. --------
  33. The USB hardware is similar to the S3C2410, with extended clock source
  34. control. The OHCI portion is supported by the ohci-s3c2410 driver, and
  35. the clock control selection is supported by the core clock code.
  36. USB Device
  37. ----------
  38. No current support in the kernel
  39. IRQs
  40. ----
  41. All the standard, and external interrupt sources are supported. The
  42. extra sub-sources are not yet supported.
  43. RTC
  44. ---
  45. The RTC hardware is similar to the S3C2410, and is supported by the
  46. s3c2410-rtc driver.
  47. Watchdog
  48. --------
  49. The watchdog hardware is the same as the S3C2410, and is supported by
  50. the s3c2410_wdt driver.
  51. MMC/SD/SDIO
  52. -----------
  53. No current support for the MMC/SD/SDIO block.
  54. IIC
  55. ---
  56. The IIC hardware is the same as the S3C2410, and is supported by the
  57. i2c-s3c24xx driver.
  58. IIS
  59. ---
  60. No current support for the IIS interface.
  61. SPI
  62. ---
  63. No current support for the SPI interfaces.
  64. ATA
  65. ---
  66. No current support for the on-board ATA block.
