2013-08-03staging:iio:adis16260: Add scale for the inclination channelLars-Peter Clausen
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 fixes it. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2013-08-03staging:iio:adis16260: Simplify calibscale and caliboffset readingLars-Peter Clausen
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.

2013-08-03staging:iio:adis16260: Remove separate headerLars-Peter Clausen

2013-08-03staging:iio:adis16260: Don't set default scan maskLars-Peter Clausen
The recomentation for IIO driver is to leave all scan elements off by default and let userspace decide which channels need to be enabled. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-08-03staging:iio:adis16260: Remove support for orientation mappingLars-Peter Clausen
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.

2013-08-03staging:iio:adis16260: Drop unused 'negate' propertyLars-Peter Clausen
Remove the unused 'negate' property from the driver state struct. This also means we can now use the adis struct directly as the driver data. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2013-08-03iio: core: Avoid double minus in sysfs outputOleksandr Kravchenko
This patch fixes the issue with double minus in output when reading channels from sysfs for IIO_VAL_INT_PLUS_MICRO and IIO_VAL_INT_PLUS_NANO cases. Until this patch if val and val2 both are negatives output string contains "--" before digits. It is result of "-%d..." in sprintf() format.

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.
