It doesn't do any pin muxing. It switches SoC internal USB signals between USB controllers. The pins remain the same.
Doesn't something like that already happen for the companion USB1 controllers for USB2 ports?
Did you mean USB 1.1 and USB 2.0 controllers by USB1 and USB2?
That also doesn't sound like you are changing the PHY.
I am changing one of the PHY registers that controls USB port (Renesas calls it channel) multiplexing.
I'd have thought that would happen if you had a single controller that select between multiply PHY.
No, it's not the case.
