Unfortunately I see the same problem as in v3: boot loop when powering the board from my notebook (ThinkPad X1 Nano running Ubuntu 24.04.1 LTS), see boot log below.
Patch version v2 is still running totally fine in the exact same setup (patch series on top of u-boot 2024.07, same board, same cabling).
Unfortunately I currently have no access to the miniPC (Zotac ZBOX CI620) I used as additional test platform before.
The boot log is unfortunately not very helpful. If you provide an additional patch enabling more debug output, I'm happy to retest with that (v2 and/or v4).
Here additional debug messages for the not working case (LOG_DEBUG enabled):

<Reset>
We already reached SNK_READY state, so everything should be fine and finished. But additional communication seams to cause a HARD_RESET sent by us, leading to a boot loop.
Seems to me we are not prepared for communication with port partners capable of source and sink power roles. Just a guess, though.
