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.
examples:
- |
cpus {
compatible = "nvidia,tegra194-ccplex";
nvidia,bpmp = <&bpmp>;
#address-cells = <1>;
#size-cells = <0>;
