This was tested on a NETGEAR ReadyNAS 2120 device (Marvell Armada XP based board, via DT). Signed-off-by: Arnaud Ebalard <arno@xxxxxxxxxxxx> --- Hi Guenter, As a side note, I removed the hunk that was present in previous patch to add gmt to the list of DT vendor prefixes because I noticed someone had taken care: https://lkml.org/lkml/2013/9/12/365 For the records, here is what I get on my NAS with the attached patch: root@thin:/sys# sensors g762-i2c-0-3e Adapter: mv64xxx_i2c adapter fan1: 5461 RPM (div = 1) g762-i2c-0-48 Adapter: mv64xxx_i2c adapter fan1: 5461 RPM (div = 1) g762-i2c-0-49 Adapter: mv64xxx_i2c adapter fan1: 5461 RPM (div = 1) g751-i2c-0-4c Adapter: mv64xxx_i2c adapter temp1: +30.5°C (high = +80.0°C, hyst = +75.0°C) armada_thermal-virtual-0 Adapter: Virtual device temp1: +34.2°C root@thin:/sys/bus/i2c/drivers/lm75/0-004c# ls driver modalias subsystem temp1_max uevent hwmon name temp1_input temp1_max_hyst root@thin:/sys/bus/i2c/drivers/lm75/0-004c# dmesg | grep lm [ 120.960471] lm75 0-004c: hwmon3: sensor 'g751' just by adding the following to the .dts: g751: g751@4c { compatible = "gmt,g751"; reg = <0x4c>; }; Do not hesitate to tell me if I missed something.
