b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * There are three types of container objects defined in the ACPI Spec as below.
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * PNP0A05: Generic Container Device
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran *   A device whose settings are totally controlled by its ACPI resource
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran *   information, and otherwise needs no device or bus-specific driver support.
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran *   This was originally known as Generic ISA Bus Device.
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran *   This ID should only be used for containers that do not produce resources
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran *   for consumption by child devices. Any system resources claimed by a PNP0A05
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran *   device's _CRS object must be consumed by the container itself.
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * PNP0A06: Generic Container Device
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran *   This device behaves exactly the same as the PNP0A05 device.
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran *   This was originally known as Extended I/O Bus.
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran *   This ID should only be used for containers that do not produce resources
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran *   for consumption by child devices. Any system resources claimed by a PNP0A06
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran *   device's _CRS object must be consumed by the container itself.
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran * ACPI0004: Module Device.
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran *   This device is a container object that acts as a bus node in a namespace.
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran *   A Module Device without any of the _CRS, _PRS and _SRS methods behaves
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran *   the same way as the Generic Container Devices (PNP0A05 or PNP0A06).
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran *   If the Module Device contains a _CRS method, only the resources
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran *   described in the _CRS are available for consumption by its child devices.
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran *   Also, the Module Device can support _PRS and _SRS methods if _CRS is
b72d5b75fd6f5bb08d29f65652d60058fc3a2608Michael Corcoran *   supported.
