From: Haavard Skinnemoen @ 2007-02-09 14:57 UTC (permalink / raw)
To: Linus Torvalds; +Cc: Linux Kernel, David Brownell, Andrew Morton
Linus,
Please pull the 'for-linus' branch of
git://www.atmel.no/~hskinnemoen/linux/kernel/avr32.git for-linus
to receive the following updates.
David, this means that everything should be ready for the SPI driver
on my part. I've tested it on top of this lot, and it works fine.
Haavard

Hi Linus,
Please pull
git://git.kernel.org/pub/scm/linux/kernel/git/hskinnemoen/avr32-2.6.git master
to receive the below updates. Note that I had to pull the mmc changes I
sent to Pierre in order to resolve a few conflicts in the platform code.
They are the same commits that Pierre pulled, so I believe git will
sort it out nicely.
Other than that, this is fairly boring. There is support for a few more
boards cooking, which I may be sending you in a second update if they
get finished within the next week. There are also some tricky power
management patches currently being reviewed.
I also have a large pile of patches for the not-yet-released AT32AP7200
chip, which I intend to start pushing upstream for 2.6.29 after this
merge window closes.
On the bright side, the amount of contributions from people outside
Atmel seems to be increasing steadily. Keep up the good work, everyone!
Haavard

Hi Linus,
Please pull
git://git.kernel.org/pub/scm/linux/kernel/git/hskinnemoen/avr32-2.6.git for-linus
to receive the following updates.
This has been tested somewhat less than usual since I've been traveling
for the past three weeks, but linux-next shows all green lights and
it's not going to get any better by me sitting on this stuff forever,
and the juicy stuff has been in our vendor tree for a while, so I feel
pretty confident about it. This merge ended up a bit smaller than I had
hoped for though...I might push power management support later if I
ever get home from Atlanta.
Stelian and Nicolas, once this is merged, everything should be set
for the rest of the AT91 USB stuff.

Linus,
Please pull from the 'for-linus' branch of
git://www.atmel.no/~hskinnemoen/linux/kernel/avr32.git for-linus
to receive the following updates. This includes a few build fixes, a
handful of fixes to the platform code (picked out of a patch by David
Brownell) and a SysV IPC fix. After this, SysV IPC should actually work
on AVR32 provided libc is re-built against a new set of kernel headers
(otherwise, it will be exactly as broken as before.)
