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 Documentation/core-api/printk-formats.rst | 34 ++++++--- drivers/acpi/property.c | 48 +++++++++++++ drivers/base/property.c | 83 +++++++++++++++++++-- drivers/base/swnode.c | 55 +++++++++++++- drivers/of/property.c | 16 +++++ include/linux/fwnode.h | 4 ++ include/linux/property.h | 8 ++- lib/test_printf.c | 37 ++++++++++ lib/vsprintf.c | 88 +++++++++++++---------- scripts/checkpatch.pl | 4 +- 10 files changed, 318 insertions(+), 59 deletions(-) -- 2.20.1
