5*999d7c47SAthira RajeevDescription:
6*999d7c47SAthira Rajeev		Attribute group to describe the capabilities exposed
7*999d7c47SAthira Rajeev		for a particular pmu. Each attribute of this group can
8*999d7c47SAthira Rajeev		expose information specific to a PMU, say pmu_name, so that
9*999d7c47SAthira Rajeev		userspace can understand some of the feature which the
10*999d7c47SAthira Rajeev		platform specific PMU supports.
11*999d7c47SAthira Rajeev
12*999d7c47SAthira Rajeev		One of the example available capability in supported platform
13*999d7c47SAthira Rajeev		like Intel is pmu_name, which exposes underlying CPU name known
14*999d7c47SAthira Rajeev		to the PMU driver.
