[PATCH 0/8] coresight: etmv4: make driver usable by Perf

[Mathieu Poirier]

This patchset makes the ETMv4 driver usable from Perf by way of the
recently added AUX area functionality.

The first 7 patches move code around to obtain a configuration
granularity suitable for Perf.  The last patch implement the AUX area
API.  Most of the code is made to resemble the work that was done on
ETMv3 as much as possible.

Best regards,
Mathieu
