S3C2412 ARM Linux Overview — The Linux Kernel 5.18.5-gnu-1 documentation

# S3C2412 ARM Linux Overview

## Introduction

> The S3C2412 is part of the S3C24XX range of ARM9 System-on-Chip CPUs from Samsung. This part has an ARM926-EJS core, capable of running up to 266MHz (see data-sheet for more information)

## Clock

> The core clock code provides a set of clocks to the drivers, and allows for source selection and a number of other features.

## Power

> No support for suspend/resume to RAM in the current system.

## DMA

> No current support for DMA.

## GPIO

> There is support for setting the GPIO to input/output/special function and reading or writing to them.

## UART

> The UART hardware is similar to the S3C2440, and is supported by the s3c2410 driver in the drivers/serial directory.

## NAND

> The NAND hardware is similar to the S3C2440, and is supported by the s3c2410 driver in the drivers/mtd/nand/raw directory.

## USB Host

> The USB hardware is similar to the S3C2410, with extended clock source control. The OHCI portion is supported by the ohci-s3c2410 driver, and the clock control selection is supported by the core clock code.

## USB Device

> No current support in the kernel

## IRQs

> All the standard, and external interrupt sources are supported. The extra sub-sources are not yet supported.

## RTC

> The RTC hardware is similar to the S3C2410, and is supported by the s3c2410-rtc driver.

## Watchdog

> The watchdog hardware is the same as the S3C2410, and is supported by the s3c2410_wdt driver.

## MMC/SD/SDIO

> No current support for the MMC/SD/SDIO block.

## IIC

> The IIC hardware is the same as the S3C2410, and is supported by the i2c-s3c24xx driver.

## IIS

> No current support for the IIS interface.

## SPI

> No current support for the SPI interfaces.

## ATA

> No current support for the on-board ATA block.
