LVDS pixel clock on i.MX6

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,


     30, 5,

    128, 10,





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?
