Subject: [PATCH v4 0/2] device property: Add scoped fwnode child node iterators

This series adds scoped versions of fwnode iterator macros and converts
existing manual implementation to use them.

The first patch adds the infrastructure macros following existing patterns
for scoped iterators in the kernel. The second patch demonstrates
fwnode_for_each_child_node_scoped() usage by converting existing manual
__free() usage in i2c-core-slave.c.

This series introduces infrastructure for the TM16XX driver series,
being the first user of fwnode_for_each_available_child_node_scoped().
See the related patch series:
  auxdisplay: Add TM16xx 7-segment LED matrix display controllers driver

Changes in v4:
- drop the fwnode_for_each_named_child_node_scoped() variant (no user)
- add Reviewed-by tag to commit message of patch 2/2

Changes in v3:
- Split into separate patches as requested
- Infrastructure addition in patch 1/2
- Usage example in patch 2/2

Changes in v2:
- replace manual __free(fwnode_handle) of i2c-core-slave.c with
  fwnode_for_each_child_node_scoped

Jean-François Lessard (2):
  device property: Add scoped fwnode child node iterators
  i2c: core: Use fwnode_for_each_child_node_scoped()
