2235acb218 Staging: IIO: Ring buffer: Initial pass at rarely locked ring buffer
Please note this ring buffer implementation is very much a
work in progress (and hence RFC).  In it's current form
it is stable and reasonably efficient.  There are a couple
of unlikely cases that will lead to more data being lost
that is strictly necessary. The target was for the case
of requiring regular sampling even during user space reads.

All comments welcome.

The intention is to make this only one of several
implementations with run time selection.  For now there
is only one, so it is hard coded into the drivers using it.

1637db4441 Staging: IIO: Trigger support added to core.
Add general registration support for IIO triggers.  These
are currently only used to initialize a 'poll' of a given
device.  Examples include the lis3l02dq's data ready signal
being used to initialize a read and gpio triggers being
used to allow externally synchronized sensor reading.

Each trigger can cause any number of 'consumer' devices
to be polled with each storing data into a related ring
buffer.

Two stage triggering is supported with 'fast' and 'slow'
paths.  The first is used for things like pulling a data
hold line high and the second for actual read which
may take far longer.

Changes since V2:
* As with IIO triggers now use a registration approach
  much closer to that of input leading to cleaner code.

574fb258d6 Staging: IIO: VTI sca3000 series accelerometer driver (spi)
Example of how a device with a hardware ring buffer is
handled within IIO.

Changes since V2:
* Moved to new registration functions giving much cleaner
  interface.

7026ea4b52 Staging: IIO: Add generic ring buffer support to the IIO core
This provides a unified interface for hardware and software
ring buffers.

Changes since V2:
* Moved to a more consistent structure.  Now the ring buffer
  has an associated struct device which is a child of the
  relevant iio_dev.  This in turn has two children, one
  for the event interface and one for the access interface.
  These two interfaces are now managed via cdev structures.

* Numerous minor cleanups

e435bc191f Staging: IIO: kxsd9 accelerometer minimal support
This provides only very minimal support for this device.
Note that an alternate driver has been posted to the input
mailing list.

When the original LMKL discussion that led to the descision
to develop IIO occured, the question on whether the differing
requirements of IIO and input drivers made it a good idea
to have unified drivers was left as an open question.
It still is.  All opinions on this question welcome.

a5ca2dfc4e staging: Make some structures static
This was done using a semantic patch (http://coccinelle.lip6.fr/) that
checks that the declaration is not inside a function definition, that the
defined variable is not exported using EXPORTED_SYMBOL, etc, and that the
defined variable does not occur in any other file.  If these conditions
hold, static is added before the declaration.
