Hi Jean, Guenter, A V2 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 v1: - The label is cached into the hwmon_device structure - hwmon_dev_name_is_visible() renamed to hwmon_dev_attr_is_visible() - Add missing <linux/property.h> include - The DT binding documentation of the "label" property has been dropped, and the "label" property is now supported directly in dtschema.
