+description: |
+  Device tree binding for ARM architecture-level cache description.
+  This is typically used to describe system-wide cache properties
+  that are not specific to a single CPU core.
+
+properties:
+  compatible:
+    enum:
+      - "arm,arch-cache"
+
+  cache-level:
+    description: The cache level (L1, L2, etc.).
+    $ref: /schemas/types.yaml#/definitions/uint32
+
+  cache-size:
+    description: Total size of the cache in bytes.
+    $ref: /schemas/types.yaml#/definitions/uint32
+
+  cache-line-size:
+    description: Cache line size in bytes.
+    $ref: /schemas/types.yaml#/definitions/uint32
+
+  cache-sets:
+    description: Number of cache sets.
+    $ref: /schemas/types.yaml#/definitions/uint32
+
+  cache-type:
+    description: Cache type (e.g., "unified", "instruction", "data").
+    enum:
+      - "unified"
+      - "instruction"
+      - "data"

+required:
+  - compatible
+  - cache-level
+  - cache-size
+  - cache-line-size
+  - cache-sets
+  - cache-type

+    cache-controller {

+        cache-level = <2>;
+        cache-size = <524288>;      /* 512 KB */
