Power down Thunderbolt controllers on Macs when nothing is plugged in
to save around 2W per controller.
For background info please see the cover letter of v3:
https://lkml.org/lkml/2016/12/17/56
Patches [1/8] to [3/8] need an ack from Bjorn and/or Rafael.
Patches [4/8] to [6/8] need an ack from Rafael.
Patches [7/8] to [8/8] need an ack from Andreas.
Changes since v4:
- Patch [2/8] has been reviewed by Mika. (Thanks!)
- Patch [3/8] now uses a separate helper function instead of stuffing
its code into pci_dev_check_d3cold(), as requested by Mika.
As usual the patches can be reviewed/fetched on GitHub:
https://github.com/l1k/linux/commits/thunderbolt_runpm_v5
Thanks,
Lukas
Chen Yu (1):
PM / sleep: Define constant for direct_complete
Lukas Wunner (7):
PCI: Recognize Thunderbolt devices
PCI: Allow runtime PM on Thunderbolt ports
PCI: Don't block runtime PM for Thunderbolt host hotplug ports
Revert "PM / Runtime: Remove the exported function
pm_children_suspended()"
PM: Make requirements of dev_pm_domain_set() more precise
thunderbolt: Power down controller when idle
thunderbolt: Runtime suspend NHI when idle
