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. | ||
23 | |||
24 | |||
25 | DMA | ||
26 | --- | ||
27 | |||
28 | No current support for DMA. | ||
29 | |||
30 | |||
31 | GPIO | ||
32 | ---- | ||
33 | |||
34 | There is support for setting the GPIO to input/output/special function | ||
35 | and reading or writing to them. | ||
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 | --- | ||
101 | |||
102 | No current support for the IIS interface. | ||
