   12 description: |
   13   The System Power Management (SPMI) controller is a 2-wire bus defined
   14   by the MIPI Alliance for power management control to be used on SoC designs.
   15 
   16   SPMI controllers are modelled in device tree using a generic set of
   17   bindings defined here, plus any bus controller specific properties, if
   18   needed.
   19 
   20   Each SPMI controller has zero or more child nodes (up to 16 ones), each
   21   one representing an unique slave at the bus.
