     12description: |
     13  A Simple Power-Managed Bus is a transparent bus that doesn't need a real
     14  driver, as it's typically initialized by the boot loader.
     15
     16  However, its bus controller is part of a PM domain, or under the control
     17  of a functional clock.  Hence, the bus controller's PM domain and/or
     18  clock must be enabled for child devices connected to the bus (either
     19  on-SoC or externally) to function.
     20
     21  While "simple-pm-bus" follows the "simple-bus" set of properties, as
     22  specified in the Devicetree Specification, it is not an extension of
     23  "simple-bus".
