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.
