| 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. |
