This series support Neoverse-V2 CPU in Perf Arm SPE.
The first patch adds the Neoverse-V2 part number in kernel header.
The second patch syncs the kernel change to the tools header.
The third patch adds Neoverse-V2 into perf's Neoverse SPE data source list.
Besar Wicaksono (3):
arm64: Add Neoverse-V2 part
tools headers arm64: Add Neoverse-V2 part
perf arm-spe: Add Neoverse-V2 to neoverse list

Hi Arnaldo,
Could you take these changes for perf?
[2/3] tools headers arm64: Add Neoverse-V2 part
[3/3] perf arm-spe: Add Neoverse-V2 to neoverse list
Thanks,
