s3cfb.c的来源对比

先看一下东华的4.3屏驱动程序：

看头文件：

#include <linux/wait.h>
#include <linux/fb.h>
#include <linux/delay.h>
#include <linux/platform_device.h>


#include <mach/regs-gpio.h>
#include <mach/regs-lcd.h>


#include "s3cfb.h"

其中除了s3cfb.h其它都是原生态的……就好好研究一下它的来源！

mini6410与samsung对比：

由上图可以看出：s3cfb.h各家都做了很大的改动，因此在LCD移植过程中，s3cfb.h也将是重点移植对象！！

而原生态内核中根本就没有这一头文件：
