Gen 1 and 2 chips use the same ID for NHI, bridges and switch.
Gen 3 chips and onward use a distinct ID for the NHI.

I assume this is strictly using #defines instead of bare numbers and
hence "no functional change intended."

I assume somebody else will merge this with the rest of the series.
Let me know if you need anything else from me.

Thanks, I've just posted a 3 patch series to support the Light Ridge
Thunderbolt controller and included your ack for this patch.


> I assume somebody else will merge this with the rest of the series.

The maintainer of the thunderbolt driver is Andreas Noever, however
I don't think Andreas sends pull requests to Linus. Everything in
drivers/thunderbolt/ has so far been picked up by Greg KH.

I have more thunderbolt stuff in the pipeline, some of which needs
changes to drivers/pci/. Therefore it would be ideal from my perspective
if my thunderbolt patches could go in via your tree, if that is possible.

Thank you!

Lukas

I have no objection if they go through the PCI tree, especially as
Thunderbolt really just is PCI express, it makes sense to take them that
way.

Andreas, what's your preference?  If you want me to merge Thunderbolt
stuff via my PCI tree, I can do that.  But I don't know anything about
Thunderbolt and don't have specs or ability to test it, so I would
rely on you to ack any changes.  If you'd like to merge Thunderbolt
stuff yourself, that would be less work for me, so even better :)  But
either way is fine.

Hi Bjorn,

I think merging thunderbolt through your tree makes sense, so that is
fine with me!

Best,
Andreas
