Pull device properties framework updates from Rafael Wysocki: "This introduces 'software nodes' that are analogous to the DT and ACPI firmware nodes except that they can be created by drivers themselves and do a couple of assorted cleanups. Specifics: - Introduce "software nodes", analogous to the DT and ACPI firmware nodes except that they can be created by kernel code, in order to complement fwnodes representing real firmware nodes when they are incomplete (for example missing device properties) and to supply the primary fwnode when the firmware lacks hardware description for a device completely, and replace the "property_set" struct fwnode_handle type with software nodes (Heikki Krogerus). - Clean up the just introduced software nodes support and fix a commet in the graph-handling code (Colin Ian King, Marco Felsch)" * tag 'devprop-4.21-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: device property: fix fwnode_graph_get_next_endpoint() documentation drivers: base: swnode: remove need for a temporary string for the node name device property: Remove struct property_set device property: Move device_add_properties() to swnode.c drivers: base: Introducing software nodes to the firmware node framework ACPI / glue: Add acpi_platform_notify() function drivers core: Prepare support for multiple platform notifications driver core: platform: Remove duplicated device_remove_properties() call

+Description:
+ This directory contains the details about the device that are
+ assigned in kernel (i.e. software), as opposed to the
+ firmware_node directory which contains the details that are
+ assigned for the device in firmware. The main attributes in the
+ directory will show the properties the device has, and the
+ relationship it has to some of the other devices.
