Subject: [GIT PULL] Device properties framework updates for v5.5-rc1

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 devprop-5.5-rc1

with top-most commit 1afc14032e54a7e6c38304dc9a6bda1b6416f2b7

 software node: simplify property_entry_read_string_array()

on top of commit da0c9ea146cbe92b832f1b0f694840ea8eb33cce

 Linux 5.4-rc2

to receive device properties framework updates for 5.5-rc1.

These 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).

There is a merge conflict between this and the printk tree (affecting
checkpatch.pl) that has been addressed by the appended patch from
Stephen in linux-next.

Thanks!
