Merge tag 'devprop-4.21-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
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
