Qualcomm WCD9370/WCD9375 Codec is a standalone Hi-Fi audio codec IC
connected over SoundWire. This device has two SoundWire device RX and
TX respectively, supporting 3 x ADCs, ClassH, Ear, Aux PA, 2xHPH,
6 DMICs, MBHC.

No wildcards. This is wcd9370, right?

Can it be anything else than codec?

"A reference to phandle" is not correct. Phandle is the reference.
Anyway, both are redundant.

This does not make sense without ref to dai-common, so this should point
you to missing ref.
