Jonathan Cameron 646d67b5c5 iio:cdc:ad7150: Move driver out of staging.
This capacitance to digital converter (CDC) driver is compliant with
the IIO ABI.  Note, not all features supported (e.g. window event modes)
but the driver should be in a useful functional state.

The cleanup was done against QEMU emulation of the device rather than
actual hardware.   Whilst this was a bit of an experiment, it made it
easy to confirm that the driver remained in a consistent working state
through the various refactors.  If it worked in the first place, it
should still be working after this cleanup.

Given some IIO drivers require expensive hardware setups, (not particularly
true with this one) the use of QEMU may provide a viable way forward
for providing testing during code changes where previously we'd had
to rely on sharp eyes and crossed fingers.

Note, no explicit MAINTAINERS entry as it will be covered by the
generic catch-alls for ADI and IIO drivers which are sufficient.

menuconfig IIO
tristate "Industrial I/O support"
help
The industrial I/O subsystem provides a unified framework for
drivers for many different types of embedded sensors using a
number of different physical interfaces (i2c, spi, etc).
if IIO
config IIO_BUFFER
bool "Enable buffer support within IIO"
help
Provide core support for various buffer based data
acquisition methods.

config IIO_CONFIGFS
tristate "Enable IIO configuration via configfs"
select CONFIGFS_FS
help
This allows configuring various IIO bits through configfs
(e.g. software triggers). For more info see
Documentation/iio/iio_configfs.rst.
config IIO_TRIGGER
bool "Enable triggered sampling support"
help
Provides IIO core support for triggers. Currently these
are used to initialize capture of samples to push into
buffers. The triggers are effectively a 'capture
data now' interrupt.
config IIO_CONSUMERS_PER_TRIGGER
int "Maximum number of consumers per trigger"
depends on IIO_TRIGGER
default "2"
help
This value controls the maximum number of consumers that a
given trigger may handle. Default is 2.
config IIO_SW_DEVICE
tristate "Enable software IIO device support"
select IIO_CONFIGFS
help
Provides IIO core support for software devices. A software
device can be created via configfs or directly by a driver
using the API provided.
config IIO_SW_TRIGGER
tristate "Enable software triggers support"
select IIO_CONFIGFS
help
Provides IIO core support for software triggers. A software
trigger can be created via configfs or directly by a driver
using the API provided.
config IIO_TRIGGERED_EVENT
tristate "Enable triggered events support"
select IIO_TRIGGER
help
Provides helper functions for setting up triggered events.
