The is some "magic" hard coded filtering in the replicators, which only passes through trace from a particular "source". Add a new property "filter-src" to label a phandle to the coresight trace source device matching the hard coded filtering for the port.
As mentioned in here in v3 review :
https://lkml.org/lkml/2024/8/21/597
Please do not use "src", expand it to "source"
Sure, I will update in the next patch series.
Best,
Tao
Rest looks fine.
