+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.
