Hello, dear Freescalers!

 

Please, help me with a little trouble. I'm trying to measure the temperature of CPU.

All needed modules in menuconfig and kernel_menuconfig, as I think, are switched on (hwmon, iio, lradc, collectd, libsensors, thermal).

In .dtsi :

iio_hwmon {
  compatible = "iio-hwmon";
  io-channels = <&lradc 8>;
};

 

But my directories /sys/class/hwmon/ and /sys/class/hwmon/ are empty. What's wrong with it?

 

Regards

Vladimir
