staging:iio:Documentation Simple dummy driver to explain the basics
The documenation explaining how to go about writing a driver is lagging
horribly, so here is another approach; an actual driver with
lots of explanatory comments.
Note it is currently minimal in that there are no events and no
buffer. With care they can probably be added in additional files
without messing up the clarity of what we have here.
V2: Addressed some of Manuel Stahl's feedback.
Fixed up kernel doc.

iio: impedance-analyzer: New driver for AD5933/4 Impedance Converter, Network Analyzer
The AD5933 is a high precision impedance converter system solution
that combines an on-board frequency generator with a 12-bit, 1 MSPS,
analog-to-digital converter (ADC). The frequency generator allows an
external complex impedance to be excited with a known frequency.
The response signal from the impedance is sampled by the on-board ADC
and a discrete Fourier transform (DFT) is processed by an on-chip DSP engine.
The DFT algorithm returns a real (R) and imaginary (I) data-word at each
output frequency.
Changes since V1:
Apply list review feedback:
Consistently use poll_time_jiffies.
Use be|le cpu endian helpers where applicable.
Add various comments.
Changes since V2:
Fix KernelVersion tag in Documentation.
Declare ad5933_default_pdata static.
Fix typos.

Hence IIO_TRIGGER should depend on GENERIC_HARDIRQS.
But as IIO_TRIGGER and IIO_RING_BUFFER form a maze of dependencies and selects,
just make the whole IIO subsystem depend on GENERIC_HARDIRQS.
This dependency also covers !S390, so that one can be removed again.

staging:iio: Add infrastructure for irq_chip based triggers
V3: Get rid of separate interrupt pool. This is well handled
by irq_get_descs and irq_free_descs. Two functions I simply
wasn't aware of previously. Thus the allocation for a given
trigger is now handled by core code rather than us reinventing
the wheel.
V2: Stop silly name duplication.
Move pool handling to industrialio-trigger as that is the only user.
Changed over to using irq_modify_status rather than the arm
specific set_irq_flags as per Thomas Gleixner's suggestion.

Staging: IIO: Periodic timer based trigger
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.

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.

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.

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
