[PATCH 20/31] perf vendor events arm64: fixup A53 to use recommended events
From: Arnaldo Carvalho de Melo
Date: Tue Mar 13 2018 - 08:06:47 EST
From: John Garry <john.garry@xxxxxxxxxx>
This patch fixes the ARM Cortex-A53 json to use event definition from
the ARMv8 recommended events.
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
