Hello all,


I've got lcd to show me part of picture when set kernel parameters to use default XGA mode.


I need to use lcd display with custom mx53 based board, how to properly determine "struct fb_videomode" structure from attached clocks.

I've got them from my ldc datasheet, but don't get how to calculate them to fb_videomode values.


Some general description below:
