Merge tag 'devprop-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull device properties framework updates from Rafael Wysocki:
"Add support for printing fwnode names using a new conversion specifier
"%pfw" (Sakari Ailus), clean up the software node and
efi/apple-properties code in preparation for improved software node
reference properties handling (Dmitry Torokhov) and fix the struct
fwnode_operations description (Heikki Krogerus)"
