[PATCH v3 00/15] Thunderbolt driver for Apple MacBooks

[Andreas Noever]

Hi

This is version 3 of my Thunderbolt driver for Apple hardware (see [1] for v2).

Changes since v2:
 - Use pci quirks instead of changing the pcie port driver.
 - Relax the DMI checks to run on all MacBooks with a Cactus Ridge chip (MBP
   Mid 2012 - Early 2013, MBA Mid 2012 - Early 2014). I have tested the driver
on my early 2013 MBP and have gotten reports of it working on a MBA mid 2013).
 - Fix some typos.

Limitations & Notes:
 - No chaining
 - No Apple TB display (non TB displays work)
 - Requires Matthew's acpi fixes [2]
 - Hibernate only works if you resume with the same (or similar) devices as
   during the initial boot. The memory layout reported by efi depends on
whether TB devices are connected during boot and linux refuses to resumeif the
total amount of memory differs. Suspend works fine.
 - No device handoff. The driver will not properly resume a device that was
   initially coldplugged. Unplug/replug works fine though.

To ease testing a git repository based on 3.15-rc7 can be found at:

	https://github.com/anoever/thunderbolt

The repository includes Matthew's patches.


Would it be possible to get this into 3.16?

Thanks, Andreas
