My apologies. I will clear this question with our legal team.
Meanwhile, can you (or copyright owner of irq.h, arm-gic.h (don't know who)=
) answer my second question?

2. Would it be possible for the copyright owners of these header files to m=
ake these files dual licensed, so that we are able to use these files in ou=
r dts/dtsi files?

If some non-copyleft license can be added to these files, then I can happil=
y use these files in our dts/dtsi
