Add fwnode_name_eq() to implement the functionality of of_node_name_eq() on fwnode property API. The same convention of ending the comparison at '@' (besides '\0') is applied on also both ACPI and swnode. The function is intended for comparing unit address-less node names on DT and firmware or swnodes compliant with DT bindings. Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> --- Hi Laurent, Would you be able to use this to replace of_node_name_eq()? It's fully untested. I didn't add an op for it as it rather looks like all the implentations would be the same (but with different container struct). drivers/base/property.c | 28 ++++++++++++++++++++++++++++ include/linux/property.h | 1 + 2 files changed, 29 insertions(+)
