Applied first two patches to arm64 (for-next/perf), thanks!
[1/4] perf/dwc_pcie: Add support for Picoheart vendor devices
https://git.kernel.org/arm64/c/cf65b4d765b5
[2/4] perf/dwc_pcie: Support narrowed time-based counter for long time monitoring
https://git.kernel.org/arm64/c/18ec1f543ae1
I haven't understood what you gain from the third patch. If it's purely
a dependency for the final patch, then Sashiko has left some comments
on that one:
