title: System Power Management Interface (SPMI) Controller
maintainers:
- Stephen Boyd <sboyd@kernel.org>
description: |
The System Power Management (SPMI) controller is a 2-wire bus defined
by the MIPI Alliance for power management control to be used on SoC designs.
SPMI controllers are modelled in device tree using a generic set of
bindings defined here, plus any bus controller specific properties, if
needed.
Each SPMI controller has zero or more child nodes (up to 16 ones), each
one representing an unique slave at the bus.

Annotation
- Immediate include surface: `dt-bindings/spmi/spmi.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.
