ADV7850 AutoGraphics Mode

I'm struggling with the ADV7850 in AutoGraphics mode when dealing with VGA non-VESA resolutions. I want to calculate all values from STDI or other actual samples from the source. I'd like to use sample data so I can pass on any signal that can possibly be sent by the VGA source.


Does anyone have code that calculates the pixel clock (pll_div_ratio), free run mode line length (ch1_fr_ll) and free run lines per field (cp_lcount_max)?


Thank you,
