- Address the comments from John.
- Link: https://lore.kernel.org/linux-arm-kernel/20220321070124.41338-1-liuqi115@huawei.com/
Change since v2:
- Associate CPA PMUs with CPUs online, rather than CPUs in the nearest SCCL.
- Move CPA power management to probe and remove function.
- Address the comments from John.
