+description: |
+  Samsung Exynos Automotive Abox Generic core node.
+
+  This node represents the generic Abox controller which manages
+  various Abox sub-drivers and acts as a hub connecting them to
+  SoC-level audio drivers. It provides PCM playback and capture
+  configuration, as well as dummy I2S backend handling, enabling
+  integration between Abox IP blocks and the SoC audio subsystem.
+
+  Typically, this node is used to initialize and configure playback,
+  capture, and routing between the Abox and other SoC audio components.
