触摸屏及ADC驱动在mini2440上的实现

mini2440的ADC驱动和触摸屏驱动， 包括修改后mini2440的BSP（linux-2.6.39.4）. ADC驱动注册为misc device， 挂载再platform bus 触摸屏驱动注册为input device， 挂载再platform bus上， 并根据官方自带的BSP进行修改， 使它隶属于option peature。 测试信息： #/home/readadc adc value: 416 Do you want to read again?n #/home/test_input Type is 1, code is 330, value is 1.
