OK cool.

Well in general the thing to watch out for is once you create a tree
it becomes a complete mess in about three months. Or else it just
becomes a graveyard of unmergeable patches :)

So keeping that in mind, ideally your tree would be just a daily merge
of various driver developers branches. And then try to set up things
where the responsibility of merging code upstream is on the drivers
developers. Trying to merge other people's patches upstream is not
scalable.

Other than that, you should be able to base it on some recent mainline
tag and pick in some queued up patches as needed.

That totally sounds usable to me :) Assuming you can figure out some
way to address the comments above.

For helping with contributions, I can think of a few places where
help is badly needed:

1. Remove dependencies in mainline kernel that block merging

   Maybe you can isolate some issues in mainline kernel that cause
   you problems merging your patches upstream? If so, whatever is
   needed should be done to patch away those dependencies. At least
   PM patches fit into this category..

2. Merge all am335x/beagle clone board-*.c files together

   This would help a lot when we start converting drivers to use
   device tree as it reduces the number of board-*.c files

3. Help with device tree conversion of device drivers

   Which drivers do most am335x and beagle clones use? Maybe
   you can help converting those drivers to use device tree?
   Sure some drivers depend on regulator framework conversion and
   the device tree omap_device glue layer, but there are already
   patches being posted for those

Regards,

Tony
