The values presented here are completely bogus. Also ..._available attributes
are supposed to be used for properties that only support discrete sets of
values, but we accept continuous values and will round to the next supported
frequency.

A negative sampling frequency is obviously invalid, so use kstrtouint() instead
of strict_strtoul. Also when setting a sampling frequency smaller than the
minimum supported frequency set the frequency to the minimum supported frequency
instead of just cutting off the upper bits of the raw register value.

While the inclination channel claims to support reading the scale the driver did
not implement this, so trying to read the scale results in a -EINVAL. This patch

All channels for this device have the same number of bits for calibscale and
caliboffset, there is no need to determine it dynamically based on the channel
type. Also there is no locking required since adis_read_reg_16() will take care
of proper locking on its own.

The adis16260 driver implements a unique feature in that it allows to change the
orientation of the gyroscope channel by specifying the orientation in platform
data. This feature is as far as I can see unused though and makes the driver
unnecessarily complex. So this patch removes the support for it. If it turns
out we need this, the cleanest approach to implement it is by adding support for
orientation mapping inside the IIO core so it is available to all drivers.

Remove the unused 'negate' property from the driver state struct. This also

Add a resource managed devm_iio_device_alloc()/devm_iio_device_free()
to automatically clean up any allocations made by IIO drivers,
thus leading to simplified IIO drivers code.
In addition, this will allow IIO drivers to use other devm_*() API
(like devm_request_irq) and don't care about the race between
iio_device_free() and the release of resources by Device core
during driver removing.

Keeping Makefile and Kconfig entries in alphabetical order usually works better
than just appending new entries at the end, since it reduces the amount of
conflicts. This patch adds a comment to the IIO Kconfig and Makefile files to
document that the entries should be kept in alphabetical order.
Also reorder those entries which weren't in alphabetical order yet.
