Hi, all,

 

I need a frequency of 33 MHz for the LVDS clock signal.

I have added the following mode to the ldb_modedb[] array in /drivers/video/mxc/ldb.c:

 

{

     "LDB-LG", 60, 800, 480, 30066,

     64,64,

     30, 5,

    128, 10,

    0,

     FB_VMODE_NONINTERLACED,

     FB_MODE_IS_DETAILED,},

};


In sys/class/graphics/fb0/mode I can see that the resolution is correctly set, but the frequency I can see with the oscilloscope for the LVDS clock is 38 MHz instead of the 33 MHz I want to set in the array. Because of this the display doesnt work.


Does anyone know about this issue?
