Merge tag 'devprop-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull device properties framework updates from Rafael Wysocki:
"These fix the handling of data nodes in the ACPI properties support
code, add a new helper for endpoint lookup in property graphs and
restore a comment inadvertently removed by one of previous changes.
Specifics:
- Fix the handling of data nodes in the ACPI properties support code
for devices with child devices and hierarchical _DSD properties
(Pierre-Louis Bossart).
- Add fwnode_graph_get_endpoint_by_id() helper for endpoint lookup in
device property graphs (Sakari Ailus).
- Restore the _DSD data subnodes GUID comment inadvertently removed
by one of previous changes (Shunyong Yang)"
