Linux2.6.26.5加入TFT-LCD驅動(dòng)

首先下載內核源碼，我這里用的是linux-2.6.26.5的內核源碼。

(1) 在arch/arm/mach-s3c2410/mach-smdk2410.c里添加頭文件：

#include

(2) 在arch/arm/ plat-s3c24xx / commON-smdk.c文件中添加如下信息：

#include

然后添加如下代碼：

STatic struct s3c2410fb_display qt2410_LCD_cfg[] __initdata = {

{

.LCDcon5 = S3C2410_LCDCON5_FRM565 |

S3C2410_LCDCON5_INVVCLK|

S3C2410_LCDCON5_INVVLINE |

S3C2410_LCDCON5_INVVframe.|

S3C2410_LCDCON5_PWREN |

S3C2410_LCDCON5_HWSWP,

.type = S3C2410_LCDCON1_TFT,

.width = 320,

.height = 240,

.pixclock = 100000, /* HCLK/10 */

.xres = 320,

.yres = 240,

.bpp = 16,

.left_margin = 13,

.right_margin = 8,

.hsync_len = 4,

.upper_margin = 2,

.lower_margin = 7,

.vsync_len = 4,

}

};

static struct s3c2410fb_mach_info qt2410_fb_info __initdata = {

.displays = qt2410_lcd_cfg,

.num_displays = ARRAY_SIZE(qt2410_lcd_cfg),

.default_display = 0,

.lpcsel = ((0xCE6) ~7) | 14,

};

在smdk_machine_init函數里添加：

s3c24xx_fb_set_platdata(qt2410_fb_info);

(3) 重新配置內核

# make menuconfig

Device Drivers

Graphics support→

Support for frAME. buffer devices→

(4) 重新編譯內核

#make zImage

這樣你新編譯的內核就支持LCD驅動(dòng)了。
