Looks like this audio codec is not used at all.
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

from NXP can give a hint.

That's a messed unit addressing. You have here simple-bus but no unit
addresses. Move it out of regulators node and run make dtc W=1 (it would
point you this issue).
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?

Please run dtbs_check on your DTS.
When I run "make dtbs_check" it runs quite a long time and stops with
an error. But as far as I can say there is an error coming from the
included "imx8mq.dtsi".

You can see the output here: https://pastebin.com/raw/iU2geBDh

Thank you

That's a messed unit addressing. You have here simple-bus but no unit
addresses. Move it out of regulators node and run make dtc W=1 (it would
point you this issue).
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?

Generic node names (from the dt spec candidate is "clock").
Should I simply set the node name to pcie0-clock? And pcie1-clock for
the next one?
I am fine with "pcie0-clock" or just "clock-0".

Please run dtbs_check on your DTS.
When I run "make dtbs_check" it runs quite a long time and stops with
an error. But as far as I can say there is an error coming from the
included "imx8mq.dtsi".

You can see the output here: https://pastebin.com/raw/iU2geBDh
Looks fine (except the error tool :) ).

Best regards,
Krzysztof

That's a messed unit addressing. You have here simple-bus but no unit
addresses. Move it out of regulators node and run make dtc W=1 (it would
point you this issue).
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?
make dtbs W=1
Ah ok. I was not aware of that.

Generic node names (from the dt spec candidate is "clock").
Should I simply set the node name to pcie0-clock? And pcie1-clock for
the next one?
I am fine with "pcie0-clock" or just "clock-0".
I saw now that in "imx8mq-zii-ultra.dtsi" the name
"clock-pcie0-refclk" is used. Can I use the same?

Please run dtbs_check on your DTS.
When I run "make dtbs_check" it runs quite a long time and stops with
an error. But as far as I can say there is an error coming from the
included "imx8mq.dtsi".

You can see the output here: https://pastebin.com/raw/iU2geBDh
Looks fine (except the error tool :) ).
What do you mean with error tool?

Thank you

Generic node names (from the dt spec candidate is "clock").
Should I simply set the node name to pcie0-clock? And pcie1-clock for
the next one?
I am fine with "pcie0-clock" or just "clock-0".
I saw now that in "imx8mq-zii-ultra.dtsi" the name
"clock-pcie0-refclk" is used. Can I use the same?
It's not that generic anymore - but specific, but it's also not that
important, so go ahead.
For me it is no problem to change this to pcie0-clock and pcie1-clock.
I need to make a new version anyway.

I lost some words on the wire - I meant: "except the error from the
tool itself".
