+title: NVIDIA Tegra Core Power Domain

+maintainers:

• • Dmitry Osipenko digetx@gmail.com
• • Jon Hunter jonathanh@nvidia.com
• • Thierry Reding thierry.reding@gmail.com

+properties:

• compatible:
• enum:

•  - nvidia,tegra20-core-domain
  

•  - nvidia,tegra30-core-domain
  

The file should be in bindings/power. Include also the power-domain.yaml schema.

• operating-points-v2:
• description:

•  Should contain level, voltages and opp-supported-hw property.
  

•  The supported-hw is a bitfield indicating SoC speedo or process
  

•  ID mask.
  

• "#power-domain-cells":
• const: 0
• power-supply:
• description:

•  Phandle to voltage regulator connected to the SoC Core power rail.
  

+required:

• • compatible
• • operating-points-v2
• • "#power-domain-cells"
• • power-supply

+additionalProperties: false

+examples:

• • |
• core-domain {

power-domain (to follow schema and devicetree spec)

Best regards, Krzysztof

•    compatible = "nvidia,tegra20-core-domain";
