Subject: [RFC] Second OLPC Viafb series

So this is the second series of viafb patches - the stuff that I was really
working toward since the beginning.  They depend on the previously-posted
first series.  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.

Florian, I incorporated your indexed port I/O patch, since it was an
obvious improvement and I was reworking that stuff anyway.

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:

	git://git.lwn.net/linux-2.6.git viafb-posted

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.

Florian Tobias Schandinat (1):
      viafb: package often used basic io functions

Jonathan Corbet (12):
      viafb: Move core stuff into via-core.c
      viafb: Separate global and fb-specific data
      viafb: add a driver for GPIO lines
      viafb: Convert GPIO and i2c to the new indexed port ops
      viafb: Turn GPIO and i2c into proper platform devices
      via: Do not attempt I/O on inactive I2C adapters
      viafb: Introduce viafb_find_i2c_adapter()
      via: Rationalize vt1636 detection
      viafb: Add a simple interrupt management infrastructure
      viafb: Add a simple VX855 DMA engine driver
      viafb: Reserve framebuffer memory for the upcoming camera driver
      viafb: Add a driver for the video capture engine
