For some embedded systems, a workflow involving external kernel modules
that implement IIO devices is more practical than working with in-tree
sources. However, there are number of features in the IIO KConfig that can
only be switched on by enabling a particular sensor.
This came as a request a few years back:
https://github.com/analogdevicesinc/linux/issues/140
This patch implements that request.
After a quick run-through the iio Kconfig files, 4 seem to be useful to add
titles to.
i.e. IIO_TRIGGERED_EVENT, IIO_TRIGGERED_BUFFER, IIO_BUFFER_DMAENGINE &
IIO_BUFFER_DMA.
It's possible that for some out-of-tree drivers this could be useful.

For some embedded systems, a workflow involving external kernel modules
that implement IIO devices is more practical than working with in-tree
sources.
Kconfig symbols without any titles do not show up in menuconfig, and as
such are more difficult to configure granularly, as they need to be
selected by potentially unused/un-needed drivers.
This change adds titles to the IIO DMA Kconfig symbols to address this.
This change also updates DMAengine -> DMAEngine, which is the
correct/nitpick-y name of the framework.

Kconfig symbols without any titles do not show up in menuconfig, and as
such are more difficult to configure granularly, as they need to be
selected by potentially unused/un-needed drivers.
Albeit, the IIO_TRIGGERED_EVENT is used by a single mainline driver, this
could allow for some out-of-tree drivers to use this kmod.
This change adds a title to the IIO_TRIGGERED_EVENT Kconfig symbol.

I'm not particular keen on changes to support out of tree stuff, but
these are so trivial there is effectively 0 cost to doing it
Hence, series applied to the togreg branch of iio.git and pushed out
as testing for the autobuilders to find out if I'm wrong :)
Thanks,
Jonathan
