Subject: [PATCH v5 0/8] Runtime PM for Thunderbolt on Macs

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

  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
