2 ==========================
3
4Introduction
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

12Clock
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.

31GPIO
32----
33
34 There is support for setting the GPIO to input/output/special function
35 and reading or writing to them.
36
37
38UART
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
45NAND
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
52USB 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
60USB Device
61----------
62
63 No current support in the kernel
64
65
66IRQs
67----
