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.

additionalProperties: true
