Merge tag 'devprop-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

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)"
