  2168	Description:
  2169			Read-only attribute containing the sysfs name prefix of the parent
  2170			channel for hierarchical channel relationships (e.g. "out_altvoltage0").
  2171			The prefix uniquely identifies the parent channel and can be used by
  2172			userspace to organize channels in tree-like structures that reflects
  2173			virtual or logical relationships between them.
  2174	
  2175			For example, an IIO device may expose a primary output channel as
  2176			"out_voltage0" together with a set of profile-based or mode-based
  2177			subchannels used to configure or compose the output signal. These
  2178			subchannels may carry common attributes such as frequency, phase, etc.
  2179			They do not represent physical outputs, but rather logical/virtual
  2180			channels grouping configurations that affect the primary output.
  2181			Each subchannel exposes a *_parent attribute reading "out_voltage0",
  2182			allowing userspace to group controls under the output channel they
  2183			belong to rather than treating them as unrelated top-level channels.
