eDP connection rebuild

We use DS90UH984 to drive a display with 1 port eDP interface. (SER IS 983);

During ESD test, the T-con will reset itself when detecting a error, and then send a HPD interrupt to 984,

I want to know, Does 984 can monitor the HPD signal and rebuild the eDP connection all the time during normal display?

Thanks.

Hello I think the soft reset should re-initiate link training with the screen.

I would confirm this question again, and would reply you as soon as possible.

984 does not automatically link-train upon HPD request after the initial video bringup script has been run. It will require manual SW intervention to reset 984 if link training is lost.

Fine, thanks;

So I think a eDP lost signal from T-con is necessity to the host during the FPD-LINK.
