For the USB patches, please also leave out patches touching
arch/arm/mach-omap2/devices.c. Those are almost guaranteed to
cause pointless merge conflicts with other branches.

I suggest you set up few immutable branches:

1. Minimal platform_data changes for all your USB changes

This should contain include/linux/platform_data changes and
changes to arch/arm/*omap* so me and Paul can merge it in too
to avoid merge conflicts.

2. The rest of the driver/usb changes

This can then be based on #1 branch above.

3. Changes for the .dts files for Benoit

These can be queued separately from #1 and #2 above.

Regards,

Tony
