When I set the LVDS resolution on u-boot, LVDS driver can automatically calculate timings parameters.

Could you please provide the formula of calculating timings?

For example:

I set LVDS resolution (1280*1024) on u-boot. After booting the device, type "fbset" command:

mode "1280x1024-60"

    # D: 109.004 MHz, H: 63.670 kHz, V: 59.897 Hz

    geometry 1280 1024 1280 1024 16

    timings 9174 216 80 3 29 136 7

    vsync high

    rgba 5/11,6/5,5/0,0/0

endmode

 

LVDS driver can automatically calculate timings parameters (9174 216 80 3 29 136 7).

Could you please provide the formula of calculating timings?

 

Thanks.

 

Best Regards,

Alex
