基于S3C2410平台USB Host Driver for Linux 2.6移植

USB Host Driver for Linux 2.6移植

#vi $KERNEL/arch/arm/mach-s3c2410/mach-smdk2410.c

添加头文件：

#include <asm/arch/usb-control.h>

#include <asm/arch/regs-clock.h>

#include <linux/device.h>

#include <linux/delay.h>

添加USB Host Driver注册信息：

struct s3c2410_hcd_info usb_s3c2410_info = {

              .port[0] = {

                     .flags = S3C_HCDFLG_USED

              }

};

int smdk2410_usb_init(void)

{

              /* USB */

              unsigned long upllvalue = (0x78<<12)|(0x02<<4)|(0x03);

              printk("USB Control, (c) 2006 s3c2410/n");

              s3c_device_usb.dev.platform_data = &usb_s3c2410_info;

              while(upllvalue!=__raw_readl(S3C2410_UPLLCON))

              {

                     __raw_writel(upllvalue,S3C2410_UPLLCON);

                     mdelay(1);

              }

              return 0;

}

        

 

        在smdk2410_map_io函数中调用 usb 的初始化，如下所示：

              static void __init smdk2410_map_io(void)

{

       …… //代码省略

       smdk2410_usb_init();

}
