description: |
Rockchip processors include support for multiple power domains
which can be powered up/down by software based on different
application scenarios to save power.
Power domains contained within power-controller node are
generic power domain providers documented in
Documentation/devicetree/bindings/power/power-domain.yaml.
IP cores belonging to a power domain should contain a
"power-domains" property that is a phandle for the
power domain node representing the domain.

Annotation
- Immediate include surface: `dt-bindings/clock/rk3399-cru.h`, `dt-bindings/power/rk3399-power.h`.
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
