Pull device properties framework updates from Rafael Wysocki:
"These mostly extend the device property API and make it easier to use
in some cases.
Specifics:
- Allow error pointer to be passed to fwnode APIs (Andy Shevchenko).
- Introduce fwnode_for_each_parent_node() (Andy Shevchenko, Douglas
Anderson).
- Advertise fwnode and device property count API calls (Andy
Shevchenko).
- Clean up fwnode_is_ancestor_of() (Andy Shevchenko).
- Convert device_{dma_supported,get_dma_attr} to fwnode (Sakari
Ailus).
- Release subnode properties with data nodes (Sakari Ailus).
- Add ->iomap() and ->irq_get() to fwnode operations (Sakari Ailus)"
* tag 'devprop-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
device property: Advertise fwnode and device property count API calls
device property: Fix recent breakage of fwnode_get_next_parent_dev()
device property: Drop 'test' prefix in parameters of fwnode_is_ancestor_of()
