What is the merge path for ssb nowadays?  I used to take these patches
(and I'm still happy to do so), but maybe Ralf is (or should be)
taking them now?

That depends on his speed. Last time I submitted a patch through his path,
it bitrotted for several months before it finally hit mainline.

Maybe because I felt drivers/ssb/ was outside my jurisdiction - and unlike
what alot of people may seem to think I'm not a full time MIPS kernel
hacker.

I can deal with SSB patch if you so desire - but I have no experience with
SSB, so I'd have somebody to rubberstamp non-trivial SSB patches before I
queue them up.  I can keep them either in the usual MIPS trees on
linux-mips.org or I could create a separate linux-ssb tree, depending on
what seems to be sensible.  Also, reading the entry in the maintainers
file I wonder if netdev is really the list of a choice?

Yes it is, because the bus is only used on networking devices.
(Ethernet cards, wireless cards, and network routers)
I don't think you need to create a separate tree. ssb is pretty mature. There
won't be that many patches.

OK, now I'm confused again -- should I take SSB patches, or is Ralf
going to do it? :-)

My decoder ring says, I'll do it from now on :)

Ok, nice. :)
Matthieu, can you resend them to Ralf? He doesn't have them, yet.

Off course.

BTW what's the procedure for submitting patch on mips ?
I already CC linux-mips, on the first patch submission.
Now that it is acked by maintainer, I should resend it to linux-mips + 
Ralf ?


Thanks

Well, you need to be careful. The watchdog is also used for system reboot.
Make sure to disable the watchdog driver when the bcm47xx system code wants
to use it.

Otherwise, ack. You can submit this to linville@tuxdriver.com.

It shouldn't be a problem : the system code always disable irq before 
using watchdog to reboot/halt (unless I miss other watchdog usage).
