iio:buffer.h - split into buffer.h and buffer_impl.h

2017-01-10T19:54:55+00:00

buffer.h supplies everything needed for devices using buffers.
buffer_impl.h supplies access to the internals as needed to write
a buffer implementation.

This was really motivated by the mess that turned up in the
kernel-doc documentation pulled in by the new sphinx docs.
It made it clear that our logical separations in headers were
generally terrible.  The buffer case was easy to sort out without
greatly effecting drivers so here it is.

iio:buffer: Push implementation of iio_device_attach_buffer into .c file

2017-01-10T19:54:54+00:00

This is a precursor to the splitting of buffer.h into parts relevant
to buffer implementation vs those for devices using buffers.
struct buffer is about to become opaque as far as the header is
concerned.

iio:buffer.h Reformat structure comments to be inline.

2017-01-10T19:54:49+00:00

This should make it easier to see how the structure is split into
public and private parts - reflected in the generated documentation.

Deliberately use /* instead of /** for the private elements to avoid
warnings when kernel-doc script runs.

Nothing outside of indiustrialio-buffer.c should be using this.

iio: Add buffer enable/disable callbacks

2015-10-25T13:52:31+00:00

This patch adds a enable and disable callback that is called when the
buffer is enabled/disabled. This can be used by buffer implementations that
need to do some setup or teardown work. E.g. a DMA based buffer can use
this to start/stop the DMA transfer.
