2020-04-23 Thread Imre Deak
Using an AUX channel which by default belongs to a non-TypeC PHY won't work on a TypeC PHY, since - as a side-effect besides providing an AUX channel - the AUX channel power well affects power manangement specific to the TypeC subsystem. Using a TypeC AUX channel on a non-TypeC PHY would probably a
