+description: |+
+  Tegra194 SOC has homogeneous architecture where each cluster has two
+  symmetric cores. Compatible string in "cpus" node represents the CPU
+  Complex having all clusters.
+
+properties:
+  $nodename:
+    const: cpus
+
+  compatible:
+    enum:
+      - nvidia,tegra194-ccplex
+
+  nvidia,bpmp:
+    $ref: '/schemas/types.yaml#/definitions/phandle'
+    description: |
+      Specifies the bpmp node that needs to be queried to get
+      operating point data for all CPUs.
