Commit18a3870(ACPI / PM: Expose lists of device power resources to user space) exposed the lists of ACPI power resources associated with power states of ACPI devices, but it didn't expose the lists of ACPI wakeup power resources, which also is necessary to get the full picture of dependencies between ACPI devices and power resources. For this reason, for every ACPI device node having a list of ACPI wakeup power resources associated with it, expose that list to user space in analogy with commit18a3870. Signed-off-by: Rafael J.

Description:
|
|
The /sys/devices/.../power_resources_wakeup/ directory is only
|
|
present for device objects representing ACPI device nodes that
|
|
require ACPI power resources for wakeup signaling.
|
|
|
|
If present, it contains symbolic links to device directories
|
|
representing ACPI power resources that need to be turned on for
|
|
the given device node to be able to signal wakeup. The names of
|
|
the links are the same as the names of the directories they
|
|
point to.
