针对4.3寸液晶屏LQ043T3DX02

一，由于Linux 2.6.13内核已经包含了该驱动，所以只要在平台初始化文件中对LCD进行设置、初始化即可。
#vi $KERNEL/arch/arm/mach-s3c2410/mach-smdk2410.c
添加头文件：
#include
#include
添加LCD初始化代码：
static struct s3c2410fb_mach_info s3c2410_lcd_info __initdata = {
              .fixed_syncs = 0,
              .regs = {
              //对于寄存器的设置是关键，可参考S3C2410X的手册
              //和LCD技术手册中对于LCD技术指标的描述来进行设置。
              //其中，寄存器值的宏定义在regs-lcd.h文件中。
                     .lcdcon1 = S3C2410_LCDCON1_TFT16BPP
| S3C2410_LCDCON1_TFT | S3C2410_LCDCON1_CLKVAL(5),
                     .lcdcon2 = S3C2410_LCDCON2_VBPD(2)
| S3C2410_LCDCON2_VFPD(2) | S3C2410_LCDCON2_VSPW(10),
                     .lcdcon3 = S3C2410_LCDCON3_HBPD(2)
| S3C2410_LCDCON3_HFPD(2),
                     .lcdcon4 = S3C2410_LCDCON4_MVAL(0)
| S3C2410_LCDCON4_HSPW(41),
                     .lcdcon5 = S3C2410_LCDCON5_FRM565
| S3C2410_LCDCON5_INVVLINE | S3C2410_LCDCON5_HWSWP
| S3C2410_LCDCON5_PWREN | S3C2410_LCDCON5_INVVFRAME,
              },
              .lpcsel = 0x0,
              .gpccon = 0xaaaaaaaa,
              .gpccon_mask = 0xffffffff,
              .gpcup = 0xffffffff,
              .gpcup_mask = 0xffffffff,
              .gpdcon = 0xaaaaaaaa,
              .gpdcon_mask = 0x0,
              .gpdup = 0xffffffff,
              .gpdup_mask = 0xffffffff,
              .width = 480,
              .height = 272,
              .xres = {480,480,480},
              .yres = {272,272,272},
              .bpp = {16,16,16},
};

static void __init smdk2410_lcd_init(void)
{
              set_s3c2410fb_info(&s3c2410_lcd_info);
}
最后在MACHINE_START与MACHINE_END中添加如下代码：
              .init_machine = smdk2410_lcd_init,
二 在/driver/video/s3c2410fb.h中s3c2410fb_init_registers函数中
   添加 LCD--VM信号相关消息
 
     s3c2410_gpio_cfgpin(S3C2410_GPC4,S3C2410_GPC4_OUTP);
    s3c2410_gpio_setpin(S3C2410_GPC4,0);
     msleep(10);
    s3c2410_gpio_setpin(S3C2410_GPC4,1);
