Thanks for the report!

@pld I did some tests about using the ADT controller. It works as advertised. fancontrol is inactive but fan speed is controlled automatically.

its controls are in

/sys/devices/platform/ocp@f1000000/f1011000.i2c/i2c-0/0-002e/hwmon/hwmon0
and it works the same as leds, you read the values in the "files" with cat and you write into them with echo 'something' > filename

The documentation about what each file controls is here https://www.kernel.org/doc/Documentation/hwmon/sysfs-interface

It seems I can enable the auto pwm switching with these commands, of course it does not stick after reboot (nor I was expecting it to, this has to be added to a boot script obviously)

cd /sys/devices/platform/ocp@f1000000/f1011000.i2c/i2c-0/0-002e/hwmon/hwmon0 # we go to the folder
ls # to see what files we can work with
echo 2 > pwm1_enable  # enabling automated pwm for fan 1, the only fan in the nsa310
echo 1 > pwm1_auto_channels  # this tells it to track temp1, the "case temp" I think, the one most close to my home ambient temp anyway

echo 23000 > pwm1_auto_temp_min # setting 23 degrees celsius for min temp, for the sake of always spinning the fan 
echo 45000 > pwm1_auto_temp_max #setting 45 degrees celsius for max temp, my hdds complain at these temps

Hi.
I have installed Debian-4.4.0-kirkwood-tld-1-rootfs-bodhi, upgraded to kernel linux-4.5.0-kirkwood-tld-1-bodhi.
Using kirkwood-nsa310.dtb during booting.

My NSA310 sensor is ADT7476.

How to set up system to run fancontrol or another software to control fan speed. Why sensors cannot read fan speed?
I read few topics about ADT7476 but have no idea how to set up it correct :/

Edit:
I have loaded kirkwood-nsa310a.dtb with LM85 sensor and it works fine.

when you boot you see a red light in the USB led? If yes, then your dtb is the newer one, kirkwood-nsa310b-lmsensor-redusbled.dtb

Only thing changed is the led though, you can live well with the one you have.
