+description:
+ ARMv8.2 introduces the optional Statistical Profiling Extension for collecting
+ performance sample data using an in-memory trace buffer.

+ description: |
+ The PPI to signal SPE events. For heterogeneous systems where SPE is only
+ supported on a subset of the CPUs, please consult the arm,gic-v3 binding
+ for details on describing a PPI partition.
