(Life cycle of timed output device driver)
1) register the device as the timed output
2) enable() ops is called via the sysfs
timeout > 0 : timer is activated and device is turned on
timeout = 0 : timer is cancelled and device is off
3) unregister the timed output device if not used any more
So the registered device should be disabled explicitly when the module is removed.
('disabled' means the timer is stopped and the device is turned off)
Rather than implementing that code in each driver,
just call enable() with timeout = 0 to clean up the driver.

Currently we use two different naming schemes in the IIO API, iio_verb_object
and iio_object_verb. E.g iio_device_register and iio_allocate_device. This
patches renames instances of the later to the former. The patch also renames allocate to
alloc as this seems to be the preferred form throughout the kernel.
In particular the following renames are performed by the patch:
iio_put_device -> iio_device_put
iio_allocate_device -> iio_device_alloc
iio_free_device -> iio_device_free
iio_get_trigger -> iio_trigger_get
iio_put_trigger -> iio_trigger_put
iio_allocate_trigger -> iio_trigger_alloc
iio_free_trigger -> iio_trigger_free
The conversion was done with the following coccinelle patch with manual fixes to
comments and documentation.

Previously, the touchscreen and ADC drivers of the LPC32xx SoC had a Kconfig
conflict declared because they use the same hardware. Upon the introduction of
device tree support in both drivers, the conflict must be removed to enable
the same kernel to support different hardware (configured via the device tree).

of the drivers/staging/vme/ area to drivers/vme/.
The VME device drivers have not moved out yet due to some API questions
they are still working through, that should happen soon, hopefully.

The devices supported by this drivers only have a single shift register, which
contains both the power down mode and the output sample. So writing the power
down mode and the output sample can be done by the same function. Call this
function prepare_write as it will prepare the spi message for a write. Also
introduce a small helper function which performs the whole write by calling the
chip the specific prepare function followed by a spi_sync.
The two power down bits are always placed ontop of the msb of the output sample,
so we can easily calculate their position by adding the channels shift to the
channels realbits.
