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.
