This regulator is not used on the board. Shall I set the name to 'NC'
or is there a way to completely disable this one?

The codec is not used yet in the dtb. As I saw on an other board
(imx8mn-var-som.dtsi) there was also just a placeholder. I can also
add an comment here.

About the order I did not checked correctly. I can bring this in the
right order for sure. But about the needs I hope someone from e.g.
from NXP can give a hint.

This regulator is not used on the board. Shall I set the name to 'NC'
or is there a way to completely disable this one?

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 could not find a matching name like "fan" in the devicetree

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 could not find a matching name like "fan" in the devicetree
