Qualcomm WCD9370/WCD9375 Codec is a standalone Hi-Fi audio codec IC
connected over SoundWire. This device has two SoundWire devices RX and
TX respectively.
This binding is for those slave devices on WCD9370/WCD9375.

Are there constraints on the values of the entries?
The port mapping entries are fixed values.
There is no constraints.
Thanks
