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 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. 103 104 105 SPI 106 --- 107 108 No current support for the SPI interfaces. 109 110 111 ATA 112 --- 113 114 No current support for the on-board ATA block. 115 116 117 Document Author 118 --------------- 119 120 Ben Dooks, Copyright 2006 Simtec Electronics
