Subject[PATCH v4 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 details see the cover letter of v3:
https://lkml.org/lkml/2016/12/17/56


Patches [1/7] to [3/7] need an ack from Bjorn (and possibly Rafael or
Mika). Patches [4/7] to [6/7] need an ack from Rafael.


Changes since v3:

- Additional patch [6/8] by Chen Yu to define a DPM_DIRECT_COMPLETE macro.
I had expected this to land in v4.10 but it didn't.

- Rework patch [7/8] ("thunderbolt: Power down controller when idle")
according to Andy Shevchenko's feedback: Drop unnecessary #ifdef pr_fmt,
add explanatory comments, rename goto labels.

- Fix error path if the upstream bridge cannot be found.

The patches are also browseable on GitHub:
https://github.com/l1k/linux/commits/thunderbolt_runpm_v4

Thanks,

Lukas
