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)" * tag 'devprop-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (22 commits) software node: simplify property_entry_read_string_array() software node: unify PROPERTY_ENTRY_XXX macros software node: remove property_entry_read_uNN_array functions software node: get rid of property_set_pointer() software node: clean up property_copy_string_array() software node: mark internal macros with double underscores efi/apple-properties: use PROPERTY_ENTRY_U8_ARRAY_LEN software node: introduce PROPERTY_ENTRY_XXX_ARRAY_LEN() software node: remove DEV_PROP_MAX device property: Fix the description of struct fwnode_operations lib/test_printf: Add tests for %pfw printk modifier lib/vsprintf: Add %pfw conversion specifier for printing fwnode names lib/vsprintf: OF nodes are first and foremost, struct device_nodes lib/vsprintf: Make use of fwnode API to obtain node names and separators lib/vsprintf: Add a note on re-using %pf or %pF lib/vsprintf: Remove support for %pF and %pf in favour of %pS and %ps device property: Add a function to obtain a node's prefix device property: Add fwnode_get_name for returning the name of a node device property: Add functions for accessing node's parents device property: Move fwnode_get_parent() up ...
