- rebased on kernel v5.14-rc5
- disable sampling events via PERF_PMU_CAP_NO_INTERRUPT (Will Deacon)
- convert tad pmu bindings to schema (Will Deacon)
- replace tighter semantics with *_relaxed() accesses (Will Deacon)
- use PMU_EVENT_ATTR_ID generic macro (Will Deacon)
- allow cleanup of allocations through devm_kcalloc() (Will Deacon)
v2:
- rebased on kernel v5.13-rc3
