Indeed, I believe the OF graph error is just a meaningless annoyance, 
but the general problem sounds like it's probably the same thing that's 
come up before:

https://lore.kernel.org/all/0ac6bbe7-6395-526d-213c-ac58a19d8673@xxxxxxxxxxxxx/

Disabling CONFIG_TYPEC_FUSB302 or blacklisting the fusb302 module should 
help confirm that. I have no idea if it's still an open problem, or if 
it's been fixed and you might just need to define the proper power role 
in the DT; this just triggered a memory of that older thread :)
