I couldn't find anything there which implied any required ordering (I'm reading Release 2.0, Aug 2019, so I don't know if something has been added since). Could you kindly point me to the appropriate subsection? Additionally, I think any ordering requirements there are already handled by the TCPM in the Chrome OS EC. > > Also I see in USB Type-C Port Manager driver the above mentioned sequence > being followed > https://elixir.bootlin.com/linux/latest/source/drivers/usb/typec/tcpm/tcpm.c#L664 In addition to the above, note that this is a TCPM implementation (on Chrome OS the TCPM implementation is in the EC), so what is done there doesn't necessarily apply to cros-ec-typec.
