让OK6410 linux支持自己的LCD

OK6410自带的那块LCD分辨率太低了,我自己在淘宝上面淘了一块5寸的LCD,分辨率800*480,与飞凌驱动里面7寸屏分辨率一样,我就改动了一下时序参数,能用了,但是有部分不大清晰,最终发现时由于时钟边沿有效设置错了,

static void s3cfb_set_fimd_info(void)
{
	s3cfb_fimd.vidcon1 = S3C_VIDCON1_IVCLK_RISE_EDGE | S3C_VIDCON1_IHSYNC_INVERT | S3C_VIDCON1_IVSYNC_INVERT | S3C_VIDCON1_IVDEN_NORMAL;//S3C_VIDCON1_IVCLK_RISE_EDGE自己添加的

通过裸机程序驱动这块LCD知道了时序参数,根据自己的屏稍作修改就可以了.

LCD驱动文件路径:/drivers/video/samsung  修改后编译内核,按照飞凌手册上面的方法更改LCD分辨率就行了.
