Hi all,

This set adds functionality into the device property API (counting a
node's parents as well as obtaining its name) in order to support printing
fwnode names using a new conversion specifier "%pfw". The names that are
produced are equivalent to its OF counterpart "%pOF" on OF systems for the
two supported modifiers ("f" and "P").

Printing a node's name is something that's been available on OF for a long
time and if something is converted to device property API (such as the
V4L2 fwnode framework) it always got removed of a nice feature that was
sometimes essential in debugging. With this set, that no longer is the
case.

since v2:

- Better comments in acpi_fwnode_get_name_prefix().

- Added swnode implementation.

- Fixed swnode refcounting in get_parent() ("swnode: Get reference to
  parent swnode in get_parent op")

- Make argument to to_software_node() const (a new patch)

- Factored out confusingly named kobject_string() that had a single
  caller.

- Cleaner fwnode_count_parents() implementation (as discussed in review).

- Made fwnode_count_parents() argument const.

- Added tests (last patch in the set).

since v1:

- Add patch to remove support for %pf and %pF (depends on another patch
  removing all use of %pf and %pF) (now 4th patch)

- Fix kerneldoc argument documentation for fwnode_get_name (2nd patch)

- Align kerneldoc style with the rest of drivers/base/property.c (no extra
  newline after function name)

- Make checkpatch.pl complain about "%pf" not followed by "w" (6th patch)

- WARN_ONCE() on use of invalid conversion specifiers ("%pf" not followed
  by "w")

Sakari Ailus (10):
  software node: Get reference to parent swnode in get_parent op
  software node: Make argument to to_software_node const
  device property: Add functions for accessing node's parents
  device property: Add fwnode_get_name for returning the name of a node
  device property: Add a function to obtain a node's prefix
  lib/vsprintf: Remove support for %pF and %pf in favour of %pS and %ps
  lib/vsprintf: Make use of fwnode API to obtain node names and
    separators
  lib/vsprintf: OF nodes are first and foremost, struct device_nodes
  lib/vsprintf: Add %pfw conversion specifier for printing fwnode names
  lib/test_printf: Add tests for %pfw printk modifier
