+description:
+  The DAB hardware accelerator found on some R-Car devices is a hardware
+  accelerator for software DAB demodulators.
+  It consists of one FFT (Fast Fourier Transform) module and one decoder module,
+  compatible with DAB specification (ETSI EN 300 401 and ETSI TS 102 563).
+  The decoder module can perform FIC decoding and MSC decoding processing from
+  de-puncture to final decoded result.
+
+properties:
+  compatible:
+    items:
+      - enum:
+          - renesas,dab-r8a77965     # R-Car M3-N
+          - renesas,dab-r8a77990     # R-Car E3

   Why not renesas,<soc>-dab?

+      - const: renesas,rcar-gen3-dab # Generic fallback for R-Car Gen3 devices
