Pull device properties framework updates from Rafael Wysocki: "These add helpers for counting items in a property array and extend the "software nodes" support to be more convenient for representing device properties supplied by drivers and make the intel_cht_int33fe driver use that. Specifics: - Add helpers to count items in a property array (Andy Shevchenko). - Extend "software nodes" support to be more convenient for representing device properties supplied by drivers (Heikki Krogerus). - Add device_find_child_by_name() helper to the driver core (Heikki Krogerus). - Extend device connection code to also look for references provided via fwnode pointers (Heikki Krogerus). - Start to register proper struct device objects for USB Type-C muxes and orientation switches (Heikki Krogerus). - Update the intel_cht_int33fe driver to describe devices in a more general way with the help of "software nodes" (Heikki Krogerus)" * tag 'devprop-5.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: device property: Add helpers to count items in an array platform/x86: intel_cht_int33fe: Replacing the old connections with references platform/x86: intel_cht_int33fe: Supply fwnodes for the external dependencies platform/x86: intel_cht_int33fe: Provide fwnode for the USB connector platform/x86: intel_cht_int33fe: Provide software nodes for the devices platform/x86: intel_cht_int33fe: Remove unused fusb302 device property platform/x86: intel_cht_int33fe: Register max17047 in its own function usb: typec: Registering real device entries for the muxes device connection: Find connections also by checking the references device property: Introduce fwnode_find_reference() ACPI / property: Don't limit named child node matching to data nodes driver core: Add helper device_find_child_by_name() software node: Add software_node_get_reference_args() software node: Use kobject name when finding child nodes by name software node: Add support for static node descriptors software node: Simplify software_node_release() function software node: Allow node creation without properties
