I used an iMX53 QSB with LVDS panel and linux kernel 184.108.40.206 from source bundle
I made it work by adding this lvds configuration into
"struct fb_videomode video_modes" in mx53_loco.c and ldb.c
/*name =*/ "NEC-VGA",
/*refresh =*/ 50,
/*xres =*/ 640,
/*yres =*/ 480,
/*pixclock =*/ 22000, /* in picoseconds! */
/*left_margin =*/ 16, /* HTOT - (HSYNSLEN + HSYNSTART) */
/*right_margin =*/ 30, /* HSYNSTART - XRES */
/*upper_margin =*/ 2, /* VTOT - (VSYNLEN + VSYNSTART) */
/*lower_margin =*/ 2, /* VSYNSTART - YRES */
/*hsync_len =*/ 100,
/*vsync_len =*/ 20,
/*sync =*/ FB_SYNC_CLK_LAT_FALL | FB_SYNC_HOR_HIGH_ACT | FB_SYNC_VERT_HIGH_ACT,
/*vmode =*/ FB_VMODE_NONINTERLACED,
/*flag =*/ 0,
with tu uBoot argument "video=mxcdi0fb:RGB666,NEC-VGA ldb"
Now I just bought a new QSB-R (with the mc34708 instead of da9053).
So I compiled the kernel (same version) with the latest patches (from 11.09.01 source bundle) to get mc34708 support.
And there, the LVDS doesn't work anymore! (with the same configuration)
I tried my old kernel and the lvds is working so that's not an hardware problem.
