[PATCH 00/14] IIO V4. Industrial I/O Subsystem

[Jonathan Cameron]

Major changes since last version:

* Allocation of most internal structures now handled in a much
  simpler fashion - very close to how input does it.
* Moved to cdev based dynamic allocation of all chrdevs.
* Cleaner and more modular code.
* Now works fine with udev
* Patch series reordered in order to aid review by adding devices
  as soon as there is sufficient support.
* Software ring buffer code thoroughly reworked.  Now much
  more reliable.now reasonably happy with the core design so all
  comments on the contents of the first patch especially welcome.
* Numerous minor fixes, clarifications etc

As is readily apparent from the patches, some are still very much
at the proof of concept stage.  The periodic rtc trigger is a tempoary
stop gap until a more suitable timer interface is available. The gpio
trigger is very minimal. Finally the documenation clearly still needs
considerable refinement.

Thanks to everyone who has helped with comments on the previous versions
and to the users for bug reports etc.

All comments on any aspect so design or indeed specific elements of the
patches would be most welcome! More formal reviews also welcome if
anyone has time.  Suggestions relating to moving towards merging this
also particuarly welcome.

For now I'll still be reworking this patch set in response to reviews,
so I wouldn't suggest using the tree as the basis of development just yet.

Updated white paper describing the subsystem to appear in the
next few days.

Note that I'm still not all that convinced by the name.
Other suggestions would be most welcome.
