Hi,
I added Bjorn, the linux-arm-msm maintainer to CC as he was missing for
some reason.

Why should everybody want coresight? It's not enabled on (most)
production devices and may cause a platform crash when you try to use it
on such ones.
These nodes should probably be added to sm8250.dtsi, all with status =
"disabled" by default, so that they don't break the devices that do not
support it due to fuse configuration.
