Hi Greg,

Understood, thanks for letting us know.

Regarding your question: since this introduces a new 
drivers/hwtracing/qcom directory, there is no existing maintainer for it.
Given your scope (and Alexander's), we believe you are the most relevant 
reviewers.

The reason for creating the qcom directory is as follows:

/We previously tried to upstream this driver under 
drivers/hwtracing/coresight,/
/but it was not accepted as it is considered Qualcomm-specific and not 
tightly/
/coupled with the CoreSight subsystem. Based on this feedback, we are 
exploring/
/a dedicated drivers/hwtracing/qcom directory, similar to intel_th, to 
better/
/support this and future Qualcomm hwtracing drivers./

More details can be found in “[PATCH v14 0/7] -- Why we are proposing this”.

Thanks,
Songwei
