Please add the support of this panel to drivers/gpu/drm/panel/panel-simple.c.

Then you can refer its compatible in your board dts.
Yes, I'm trying to add the display timings but I couldn't find any
info how to find front_portch, back_porch and sync. I remember
blanking time = Sync Width + BP + FP so out of which how can we
determine each one respectively. Please let me know if you have any
idea, I?ve attached the data-sheet.
Does the existing ampire,am800480r3tmqwa1h binding work for your display?

Yes, it is working..but need to understand how these respective
timings were calculated(because I need to add few more) . I tried this
supported ampire but couldn't get the data-sheet. Please point me if
you find any details.

thanks!
