I was also trying to eliminate the warning concerning the lack of port with limited success. I also missed the interrupt pin definition I see. I will test this later today. Where you successful in your testing? My type-c exposure is somewhat limited so it would be nice to get another opinion ;-) > I've added Neil Armstrong for information in case any boards on the Amlogic side are similarly configured, I think a few other Rockchip ones at least are missing connector nodes, it appears to be a consistent issue presumably due to driver changes. The whole type-c topic is a somewhat undiscovered country on rk3399, due to the cross-ec hooking rk3399's type-c components. (see the cros-ec-pd extcon going to the rockchip type-c phy etc). This is presently worked on so that also everything can at some point use the kernel-internal type-c framework. But of course this doesn't hinder configuring the power-develivery in the fusb302 ICs already :-D . Heiko
