Hi Guenter, Jean,
I've got a requirement to add some meaningful names to some hwmon sensors (LM75 specifically) so that we can provide some indication of where on a board the sensor is located (e.g. "Intake" vs "Exhaust" vs "Near that really hot chip").
I see that the sysfs ABI documents both "label" for the chip and "temp[1-*]_label" (as well as similar fan and Vin attributes). The latter seem to be supported by the hwmon core but I don't see anything for the former (I'm struggling to find any driver that supports a chip-wide label).
Assuming I want to have a label added in the device tree to a lm75 would something like the following be acceptable
sensor@48 { compatible = "national,lm75"; reg = <0x48>; label = "Intake"; };
I'd then update the lm75 driver to grab that from the devicetree and use it to provide the hwmon_temp_label attribute.
Thanks, Chris
