[RFC] Second OLPC Viafb series, v2

[Jonathan Corbet]

This is the second posting of the second series of viafb patches.  What's
added here is a big refactoring of the driver to split its functions apart
and the addition of code for GPIO, interrupt, DMA, and camera management.

The following changes have been made since the first version:

 - A couple of small fixes have been made to the first series.  The
   OLPC-specific tests for i2c access have been removed since they broke
   the linux-next build, and we don't try to do i2c on ports which have not
   traditionally been used that way.  For that reason, I'm including that
   initial series here; the whole set applies to 2.6.34-rc3.

 - The build problems encountered by Florian (GPIOLIB and module stuff)
   have been fixed.  I have *not* made fb/i2c/gpio into separate modules at
   this point, though that is the clear destination of this work.  That's a
   bit messy and I didn't want to complicate these patches further; I will
   do it in the future.

 - I merged in all of Florian's cleanup patches from a couple of weeks
   ago.  I've not looked at the new suspend/resume patches yet.

Note that the camera driver (the last in the series) is not yet ready for
submission; I add it here for completeness.

The full series of patches can be pulled from:

Some of this stuff is disruptive, and I only have one machine to test it
all on, so I'd really appreciate it if folks with other types of hardware
could try them out.
