title: System Power Management Interface (SPMI) Controller
maintainers:

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.
