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.

Do not need '|' unless you need to preserve formatting.

ACK

will remove '|' in next version patch set.


+  Qualcomm WCD9370 Codec is a standalone Hi-Fi audio codec IC.
+  It has RX and TX Soundwire slave devices. This bindings is for the
+  slave devices.

+      In the order of slave port index.

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

ACK


+    $ref: /schemas/types.yaml#/definitions/uint32-array
+    minItems: 4
+    maxItems: 4

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

+
+  qcom,rx-port-mapping:
+    description: |
+      Specifies static port mapping between slave and master rx ports.
+      In the order of slave port index.
+    $ref: /schemas/types.yaml#/definitions/uint32-array
+    minItems: 5
+    maxItems: 5
+
+required:
+  - compatible
+  - reg
+  - qcom,port-mapping

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?

ACK,

will fix the binding errors.

Drop unit address.


actually took the reference from wcd938x.

https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/Documentation/devicetree/bindings/sound/qcom,wcd938x-sdw.yaml#n48



+        #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.

Krzysztof
