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 hardware is the same as the S3C2410, and is supported by
84	  the s3c2410_wdt driver.
85	
86

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.
103	
104	
105	SPI
106	---
107	
108	  No current support for the SPI interfaces.
109
