The original posting of this driver led to a discussion in
which it was commented that a better system was needed
for dealing with the many possible periodic interrupt
sources available on some SoCs. Unfortunately that is
a big task and as far as I know, no-one has taken it
on as yet. So in the meantime this driver is still
in here.

Example of relatively common case of device sampling
based on internal clock and providing a data ready
signal to indicate that new data is available to be
read out.
Generic trigger approach used to allow other devices
to be sampled 'at the same time' as this the accelerometer.
This is very useful in various motion estimation algorithms.

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.

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.

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

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.
