[PATCH 8/9] perf utils: fixup ARM Cortex A53 JSONs to use ARMv8 recommended events

John Garry john.garry at huawei.com
Tue Feb 6 09:45:03 PST 2018


This patch fixes the ARM Cortex-A53 json to use event definitions
from the ARMv8 recommended events.

The brief description is kept for readability for arch standard events,
but is not strictly required.

In addition to this change, other changes were made:
- remove stray ','
- remove mirrored events in memory.json and bus.json
- fixed indentation to be consistent with other ARM
  JSONs
