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()
