However, its bus controller is part of a PM domain, or under the control of a functional clock. Hence, the bus controller's PM domain and/or clock must be enabled for child devices connected to the bus (either on-SoC or externally) to function. While "simple-pm-bus" follows the "simple-bus" set of properties, as specified in the Devicetree Specification, it is not an extension of "simple-bus". properties: $nodename: pattern: "^bus(@[0-9a-f]+)?$" compatible: contains: const: simple-pm-bus description: Shall contain "simple-pm-bus" in addition to a optional bus-specific compatible strings defined in individual pm-bus bindings.
