Subject: [PATCH 00/14] coresight: tmc: make driver usable by Perf 

This patchset makes the TMC driver usable from Perf by way of the
recently added AUX area functionality.

The first 11 patches remodel the driver so that the functionality
is compartmented enough to be used as building blocks when interfacing
with the Perf subsystem.

Path 12 and 13 implement the AUX area API, taking heavily on the existing
ETB10 implementation.

Finally patch 14 allows the TMC to be used as a link rather than a sink,
something that is required when dealing with an ETF component.

Best regards,
Mathieu
