iio: imu: adis16550: add adis16550 support

The ADIS16550 is a complete inertial system that includes a triaxis
gyroscope and a triaxis accelerometer. Each inertial sensor in the
ADIS16550 combines industry leading MEMS only technology with signal
conditioning that optimizes dynamic performance. The factory calibration
characterizes each sensor for sensitivity, bias, and alignment. As a
result, each sensor has its own dynamic compensation formulas that
provide accurate sensor measurements.

iio: imu: add Bosch Sensortec BNO055 core driver

Add the core driver for the BNO055 IMU from Bosch. This IMU can be
connected via both serial and I2C busses; separate patches will add support
for them.

The driver supports "AMG" (Accelerometer, Magnetometer, Gyroscope) mode,
that provides raw data from the said internal sensors, and a couple of
"fusion" modes (i.e. the IMU also does calculations in order to provide
euler angles, quaternions, linear acceleration and gravity measurements).

In fusion modes the AMG data is still available (with some calibration
refinements done by the IMU), but certain settings such as low pass filters
cut-off frequency and sensors' ranges are fixed, while in AMG mode they can
be customized; this is why AMG mode can still be interesting.

iio: st_sensors: Add lsm9ds0 IMU support

We can utilize separate drivers for accelerometer and magnetometer,
so here is the glue driver to enable LSM9DS0 IMU support.

The idea was suggested by Crestez Dan Leonard in [1]. The proposed change
was sent as RFC due to race condition concerns, which are indeed possible.

In order to amend the initial change, I went further by providing a specific
multi-instantiate probe driver that reuses existing accelerometer and
magnetometer.

FXOS8700CQ has dynamically selectable accelerationfull-scale ranges of
±2 g/±4 g/±8 g and a fixed magnetic measurement range of ±1200 μT.
Output data rates (ODR) from 1.563 Hz to 800 Hz are selectable by the user
for each sensor. Interleaved magnetic and acceleration data is available
at ODR rates of up to 400 Hz. FXOS8700CQ is available in a plastic QFN
package and it is guaranteed to operate over the extended temperature
range of –40 °C to +85 °C.

iio: imu: Add support for the ADIS16460 IMU

The ADIS16460 device is a complete inertial system that includes a triaxial
gyroscope and a triaxial accelerometer. It's more simplified design than
that of the ADIS16480, and does not offer the triaxial magnetometers &
pressure sensors. It does also have a temperature sensor (like the
ADIS16480).
Since it is part of the ADIS16XXX family, it re-uses parts of the ADIS
library.

Naturally, the register map is different and much more simplified than the
ADIS16480 subfamily, so it cannot be integrated into that driver. A major
difference is that the registers are not paged.

One thing that is particularly special about it, is that it requires a
higher delay between CS changes (i.e. when CS goes up, the spec recommends
that it be brought down after a minimum of 16 uS).
Other ADIS chips require (via spec) a minimum of 2 uS between CS changes.
The kernel's 10 uS default should be fine for those other chips; they
haven't been tested with lower CS change delays yet.
