562306a36Sopenharmony_ci		Information about whether a given device can be removed from the
662306a36Sopenharmony_ci		platform by the	user. This is determined by its subsystem in a
762306a36Sopenharmony_ci		bus / platform-specific way. This attribute is only present for
862306a36Sopenharmony_ci		devices that can support determining such information:
