PHY0 and PHY2 share power and ground, PHY0 contains shared registers.
PHY0 and PHY2 must specify two register sets, where the first set is
PHY own registers and the second set is the PHY0 registers.

Annotation
- Immediate include surface: `dt-bindings/clock/tegra124-car.h`, `dt-bindings/clock/tegra20-car.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.
