5*41a2a466SRafael J. Wysocki		The /sys/devices/.../power_resources_wakeup/ directory is only
6*41a2a466SRafael J. Wysocki		present for device objects representing ACPI device nodes that
7*41a2a466SRafael J. Wysocki		require ACPI power resources for wakeup signaling.
8*41a2a466SRafael J. Wysocki
9*41a2a466SRafael J. Wysocki		If present, it contains symbolic links to device directories
10*41a2a466SRafael J. Wysocki		representing ACPI power resources that need to be turned on for
11*41a2a466SRafael J. Wysocki		the given device node to be able to signal wakeup.  The names of
12*41a2a466SRafael J. Wysocki		the links are the same as the names of the directories they
