Ok, I will change that.

But I'm not able to run dtc on my dts. dtc throws an error.

# dtc -I dts -O dtb imx8mq-kontron-pitx-imx8m.dts
Error: imx8mq-kontron-pitx-imx8m.dts:10.1-9 syntax error
FATAL ERROR: Unable to parse input tree

It is about the includes. How can I run dtc for a intree dts to add
the -W option?

Should I simply set the node name to pcie0-clock? And pcie1-clock for
the next one?

I will change to tpm@0.

I could not find a matching name like "fan" in the devicetree
specification. What about using "fan-ctrl"?
