There was a problem hiding this comment.
Tested on lemp13-b. Hotplugging HDMI worked before this change, but it also still works after the change.

HDMI_HPDis connected toDDSP_HPD2. Since MTL, DDSP is also 0-indexed, but port mappings remain 1-indexed.Does HDMI HPD work on MTL boards?
Do TBT/USB-C need to be added to
ddi_ports_configas well?Intel also just pushed this for Google Atria (NVL)
TCP[0-2] are used, but not declared in the FSP config. Only eDP on DDI-A and HDMI on "DDI-4", which I can only assume is TCP3.
