Hmm... here, I got a different set of patches...
I've created a quilt tree with the DaVinci patches I have here:
http://linuxtv.org/downloads/patches-davinci/
There are 3 patches touching arch/arm:
$ grep -l arch/arm *
arch_arm_mach_davinci_platform_and_board_specific_setup_for_dm646x_evm.patch
v4l_dvb_dm355_platform_changes_for_vpfe_capture_driver.patch
v4l_dvb_dm6446_platform_changes_for_vpfe_capture_driver.patch
All those three files touches just arch/arm files:
$ diffstat -p1 `grep -l arch/arm *`
arch/arm/mach-davinci/board-dm355-evm.c | 76 ++++++++++++++++-
arch/arm/mach-davinci/board-dm644x-evm.c | 72 ++++++++++++++++

10 files changed, 503 insertions(+), 5 deletions(-)
If I move those tree files out, the remaining ones are touching only on

Agreed. I dropped the 3 arch patches from my tree:
http://linuxtv.org/downloads/patches-davinci/arch_arm_mach_davinci_platform_and_board_specific_setup_for_dm646x_evm.patch
http://linuxtv.org/downloads/patches-davinci/v4l_dvb_dm355_platform_changes_for_vpfe_capture_driver.patch
http://linuxtv.org/downloads/patches-davinci/v4l_dvb_dm6446_platform_changes_for_vpfe_capture_driver.patch
Could you please check those 3 patches and see what's missing on your tree?
That's said, we need to make sure that Stephen will merge both trees, otherwise
compilation will break for DaVinci. As the Makefiles are the last ones on my
tree, provided that I merge the DaVinci patches after you, we shouldn't have
troubles upstream.
P. S. I've removed DaVinci ML, as it is a subscription-only list and I'm not
subscribed there.
