Please describe the hardware, not the usecase. If there are other trace
cells, please add them.

Hmm, ok so I added the other CPUs and I was able to trace on all cpus, so I was wondering why
at least those were not added because having only ete0 declared is quite useless.

Please adopt the expected subject style of:
"arm64: dts: qcom: <platform>[-board]: Subject"
Run "git log --oneline -- <file>" if you're uncertain how it should
look.
I'm correcting this one while applying it, no need to resend.
Thanks,
