[LTIB 4.0] i.MX6 How to calculate the timings parameter of lvds panel

[charleshuang]

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

Hi charles

for new lcd timings configuration one can look at

Chapter 18 Connecting an LVDS Panel i.MX53 System Development User’s Guide.

http://www.freescale.com/files/32bit/doc/user_guide/MX53UG.pdf

However I do not think that u-boot-2009.08 automatically calculate timings,

probably it adjusts it to most close value.

Best regards
