Hi all,

In recent days, I tested the fusb302 driver with tcpm. (RK3399 evb board)
But I found an issues:
There is not a regulator for type-c vbus power-supply in my board.
The vbus is just controlled by a gpio-pin, and unable to support other voltage except 5V.
But now, I can't use fusb302 driver without workaround fix.
Could you fix it in next version? @Yueyao

The altmode looks not complete. I can't enter DP Alt Mode now.
And we'd like to used extcon function (used in Chrome) to link usb, dp and type-c together.
How do you think about it? @Guenter
