One new property usually does not justify new example. Why it cannot be
added to existing example?

Anyway, I prefer not to take any new Qualcomm Coresight bindings or
Qualcomm SoC DTS nodes with Coresight till we fix all existing warnings.
I don't know how to fix them, so I need help with them. No such fixing
happened so far from Qcom, so pushback is my only way to get any attention.

I already commented on this in other email thread.

Best regards,
