Merge tag 'devprop-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull device properties framework updates from Rafael Wysocki: "These introduce fwnode operations for all of the separate types of 'firmware nodes' that can be handled by the device properties framework, make the framework use const fwnode arguments all over, add a helper for the consolidated handling of node references and switch over the framework to the new UUID API. Specifics: - Introduce fwnode operations for all of the separate types of 'firmware nodes' that can be handled by the device properties framework and drop the type field from struct fwnode_handle (Sakari Ailus, Arnd Bergmann). - Make the device properties framework use const fwnode arguments where possible (Sakari Ailus). - Add a helper for the consolidated handling of node references to the device properties framework (Sakari Ailus). - Switch over the ACPI part of the device properties framework to the new UUID API (Andy Shevchenko)" * tag 'devprop-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI: device property: Switch to use new generic UUID API device property: export irqchip_fwnode_ops device property: Introduce fwnode_property_get_reference_args device property: Constify fwnode property API device property: Constify argument to pset fwnode backend ACPI: Constify internal fwnode arguments ACPI: Constify acpi_bus helper functions, switch to macros ACPI: Prepare for constifying acpi_get_next_subnode() fwnode argument device property: Get rid of struct fwnode_handle type field ACPI: Use IS_ERR_OR_NULL() instead of non-NULL check in is_acpi_data_node()
