具體的移植過程：

1：安放驅(qū)動(dòng)文件

把s3c2410_ts.c放到drivers/input/touchscreen下。

把ts.h放到include/asm-arm/arch-s3c2410

2：修改drivers/input/touchscreen/Kconfig

添加下列信息

config TOUCHSCREEN_S3C2410

tristate "Samsung S3C2410 touchscreen input driver"

depends on ARCH_S3C2410 && INPUT && INPUT_TOUCHSCREEN

select SERIO

help

Say Y here if you have the s3c2410 touchscreen.

If unsure, say N.

To compile this driver as a module, choose M here: the

module will be called s3c2410_ts.

config TOUCHSCREEN_S3C2410_DEBUG

boolean "Samsung S3C2410 touchscreen debug messages"

depends on TOUCHSCREEN_S3C2410

help

Select this if you want debug messages

3：修改drivers/input/touchscreen/Makefile

添加下列信息

obj-$(CONFIG_TOUCHSCREEN_S3C2410)
+= s3c2410_ts.o

4：把s3c2410_ts.c里的
#include
改成
#include

5：修改arch/arm/plat-s3c24xx/devs.c文件

添加頭文件

#include

添加

struct platform_device s3c_device_ts = {

.name= "s3c2410-ts",

.id= -1,};

EXPORT_SYMBOL(s3c_device_ts);

static struct s3c2410_ts_mach_info s3c2410ts_info;

void __init set_s3c2410ts_info(struct s3c2410_ts_mach_info *hard_s3c2410ts_info)

{memcpy(&s3c2410ts_info,hard_s3c2410ts_info,sizeof(struct s3c2410_ts_mach_info));

s3c_device_ts.dev.platform_data = &s3c2410ts_info;}

EXPORT_SYMBOL(set_s3c2410ts_info);

6：修改include/asm-arm/plat-s3c24xx/devs.h

在include/asm-arm/plat-s3c24xx/devs.h下添加：

extern struct platform_device s3c_device_ts;

7：修改arch/arm/mach-s3c2410/mach-s3c2410.c文件

添加頭文件

#include

添加

static struct s3c2410_ts_mach_info s3c2410_ts_cfg __initdata = {

.delay = 10000,

.presc = 49,

.oversampling_shift = 2,

};

在static struct platform_device *smdk2410_devices[] __initdata結(jié)構(gòu)體中添加

&s3c_device_ts,

在static void __init smdk2410_init(void)函數(shù)中添加

set_s3c2410ts_info(&s3c2410_ts_cfg);

這樣就OK了，然后記得配置內(nèi)核.make zImage
