原创 USB驱动移植

USB驱动移植
1   在arch/arm/mach-s3c2410/mach-smdk2410.c中紧接着LCD的部分添加
//usb
#include <asm/arch/usb-control.h>
#include <asm/arch/regs-clock.h>
#include <linux/device.h>
#include <linux/delay.h>
//-------------------usb两个USBHOST支持---------------
struct s3c2410_hcd_info usb_s3c2410_info = {
 .port[0] = {
  .flags = S3C_HCDFLG_USED
 }
};

int smdk2410_usb_init(void)
{
 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;
}
2   在smdk2410_map_io函数最后添加
 //usb
 smdk2410_usb_init();
------------配置USB鼠标键盘----------
