Hi Jean, Guenter, A V3 of my patchset which allows specifying a hwmon device's label from Device Tree. When the "label" device property is present, its value is exported to the userspace via the "label" sysfs attribute. This is useful for userspace to be able to identify an individual device when multiple individual chips are present in the system. Note that this mechanism already exists in IIO. Patch [1/2] documents the ABI change. Patch [2/2] adds the change to the core drivers/hwmon/hwmon.c file. Changes from v2: - Move the code setting the label around in the probe function to fix error handling issue.
