13 If the QCA8K switch is connect to an SoC's external mdio-bus, each subnode
14 describing a port needs to have a valid phandle referencing the internal PHY
15 it is connected to. This is because there is no N:N mapping of port and PHY
16 ID. To declare the internal mdio-bus configuration, declare an MDIO node in
17 the switch node and declare the phandle for the port, referencing the internal
18 PHY it is connected to. In this config, an internal mdio-bus is registered and

13 Qualcomm WCD9390/WCD9395 Codec is a standalone Hi-Fi audio codec IC.
15 The WCD9390/WCD9395 IC has a functionally separate USB-C Mux subsystem
17 The Audio Headphone and Microphone data path between the Codec and the USB-C Mux
18 subsystems are external to the IC, thus requiring DT port-endpoint graph description
