Sorry, the commit messages may not be described accurately enough.


This patch adds mux/switch operations to the PHY driver to improve 
communication with the TCPM framework. Since this PHY is a combo USB/DP 
PHY, it requires configuration changes to the PHY lanes based on the 
USB-C  plug orientation (CC logic), similar to the existing extcon 
mechanism implementation. Of course, the original extcon functionality 
will remain fully compatible.
