移植触摸屏驱动到linux3.4.2

1. 修改drivers/input/touchscreen/下的Makefile

#obj-$(CONFIG_TOUCHSCREEN_S3C2410)      += s3c2410_ts.o
obj-$(CONFIG_TOUCHSCREEN_S3C2410)       += s3c_ts.o

2.重新配置menuconfig

make menuconfig，将touchscreen编译进内核

3. 修改.config，找到CONFIG_TOUCHSCREEN_S3C2410，修改为

# CONFIG_TOUCHSCREEN_ILI210X is not set
CONFIG_TOUCHSCREEN_S3C2410=y
# CONFIG_TOUCHSCREEN_GUNZE is not set

4. make uImage

5. 下载新内核，启动开发板，cd /mnt

6. cd ts_dir

7. cp * /  -rfd

8. sh tslib.sh

9. 执行ts_calibrate以及ts_test，成功

/mnt # ts_calibrate
