Very appoligized. I forget to migrate this line from my test 5.10 kernel.
Without this line will cause sound card codec link fail.
Please use the patch v2 to review the bindings and source code.

V2
- Add missing #sound-dai-cells property.

Sorry, saw v1 before I saw this but I guess the issues still apply - a
quick check seems like it.

+description: |
+  The RT9120 is a high efficiency, I2S-input, stereo audio power amplifier
+  delivering 2*20W into 8 Ohm BTL speaker loads. It supports the wide input
+  voltage  range from 4.5V to 26.4V to meet the need on most common
+  applications like as TV, monitors. home entertainment, electronic music
+  equipment.
