In the panel device node.

Can you please share it too?

           edp_panel: edp_panel {
                   compatible = "sharp_lq140m1jw46";
Is that supposed to be sharp,lq140m1jw46 with a comma instead of an
underscore?

Stephen,

This is our internal branch which does not have patches up to date yet.

I will cherry-pick newer edp related patches which are under review now to
re test it.

Detect returned eDP not connected because the panel power was not on and mode_valid was failing because the DP mode_valid is different from eDP
