Hi all,

These are a few quality-of-life improvements for CoreSight PMU that
I've accumulated based on things which have come up in practical usage.
There's no real dependency between any of the individual patches, it
just felt right to send them as a series.

v1: https://lore.kernel.org/linux-perf-users/cover.1783605641.git.robin.murphy@arm.com/
v2: Fix valid nits from Sashiko review, add Ilkka's R-b.

Thanks,
Robin.
