Hi Gokul,

you can refer to the settings in ldb.c to support the lvds display panel.

static struct fb_videomode ldb_modedb[] = {
{
"LDB-XGA", 60, 1024, 768, 15385,
220, 40,
21, 7,
60, 10,
0,
FB_VMODE_NONINTERLACED,
FB_MODE_IS_DETAILED,},
{
"LDB-1080P60", 60, 1920, 1080, 7692,
100, 40,
30, 3,
10, 2,
0,
FB_VMODE_NONINTERLACED,
FB_MODE_IS_DETAILED,},
};

Regards,
