/*
* The TCPCI test verfies the mux behavior in two configurations:
* flags = USB_MUX_FLAG_NOT_TCPC;
* flags = 0;
*
* When USB_MUX_FLAG_NOT_TCPC is set, the TCPCI mux driver must initialize
* the I2C bus and address from the devicetree.
*
* The TCPCI mux doesn't have it's owm emulator and sends it's I2C transactions
* through the normal TCPCI driver, which then connects to the TCPCI emulator.
*
* Use 2 compaible strings here so that the same I2C device node gets setup for
* both the emulator and the TPCI mux.
