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.

Use inclusive terminology. Describe what is here - what is the index? What is the value?

Add constraints on values. You have maximum 15 TX ports, don't you?

Test your binding. There is no need to engage reviewers for reviewing simple mistakes which *tools* can point. Respect reviewers time and use the tools first.
You need oneOf: with required for TX and RX... or just unify the properties. Why do you need two?

- soundwire@3210000 {
Drop unit address.
#address-cells = <2>;#size-cells = <0>;reg = <0x03210000 0x2000>;
Drop, not relevant and not placed correctly (see DTS coding style).
wcd937x_rx: codec@0,4 {
Drop label, not used.
compatible = "sdw20217010a00";reg = <0 4>;qcom,rx-port-mapping = <1 2 3 4 5>;};- };
- soundwire@3230000 {
Drop this example, it's almost identical.
