| Message-ID | <qFZ5n-5o7-1@gated-at.bofh.it> |
Commit ac82d1277215 ("arm64: perf: add Cortex-A53 support") adds the
cortex A53 PMU support, thus instead of using the generic armv8-pmuv3
compatibility use the more specific Cortex A53 compatibility.

IMHO, we don't need to list both. The pmu binding document also says: "compatible : should be one of ...." Dear Mark, Could you please give suggestions?

It's probably best to keep "arm,armv8-pmuv3" as a fallback in the compatible list.
