Hi:
I modified “panel-a-edp-1080p-14-0.dtsi” for a 13.3 inch panel((HX133LF1L01),It’s ok.

The HX133LF1L01 only 2 lanes, but I can’t found the method to configure the number of lanes in “panel-a-edp-1080p-14-0.dtsi”, where to configure it?

XuXiang,

It seems there is no device tree configuration for such field. Could you check the driver to see if it gives the correct data lanes during link training(lt)?
