Can't read temperature

niklasmolin — Thu, 21 Dec 2017 03:46:04 GMT

I'm compiling linux 4.14 for an i.mx6QP and when I'm trying to read the temperature in

/sys/class/thermal/

there is nothing in that directory.

Is there a setting I'm missing or something I disabled in the devicetree?

Found the issue.

Made a mistake in the .dts file.
