Message-ID: <20071023114314.2348d5a0@dhcp-255-175.norway.atmel.com>
Date: Tue, 23 Oct 2007 11:43:14 +0200
From: Haavard Skinnemoen <hskinnemoen@...el.com>
To: Linus Torvalds <torvalds@...ux-foundation.org>
Cc: Linux Kernel <linux-kernel@...r.kernel.org>, kernel@...32linux.org
Subject: [GIT PULL]
Linus,
Please pull from
ssh://master.kernel.org/pub/scm/linux/kernel/git/hskinnemoen/avr32-2.6.git for-linus
to receive the following updates. This is mostly about connecting a few
loose ends that came in through other trees, that is make sure that the
new drivers can actually be used on avr32.
Alejandro Martinez Ruiz (1):
[AVR32] ARRAY_SIZE() cleanup
Haavard Skinnemoen (3):
[AVR32] Fix a couple of sparse warnings
[AVR32] Implement more at32_add_device_foo() functions
[AVR32] Implement at32_add_device_cf()
Hans-Christian Egtvedt (1):
[AVR32] Wire up AT73C213 sound driver on ATSTK1000 board
Kristoffer Nyborg Gregertsen (1):
[AVR32] Platform code for pata_at32
