MPL115 supports shutdown gpio which can be used to set the state
to low power mode. Power from all internal circuits and
registers is removed. This is done by pulling the SHDN pin to low.
This patch enables runtime PM on MPL115 to increase power savings.
According to spec., a wakeup time period of ~5 ms exists between
waking up and actually communicating with the device. This is
implemented using sleep delay.

The DPS310 chip has been observed to get "stuck" such that pressure
and temperature measurements are never indicated as "ready" in the
MEAS_CFG register. The only solution is to reset the device and try
again. In order to avoid continual failures, use a boolean flag to
only try the reset after timeout once if errors persist.

Simplified common initialization logic of different sensor types
unifying calibration and initial configuration recovery.
Default config param values of each sensor type are stored inside
chip_info structure and used to initialize sensor data struct instance.
The helper functions for read each sensor type calibration are converted
to a callback available on the chip_info struct.
Separated bme280 specific calibration code from bmp280 function. Dropped
the additional chip_id argument in bmp280 code as is not longer required.
Now both bmp280/bme280 calibration function use same signature as bmp180.

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

Instead of registering callback to process sensor events right at
initialization time, wait for the sensor to be register in the iio
subsystem.
Events can come at probe time (in case the kernel rebooted abruptly
without switching the sensor off for instance), and be sent to IIO core
before the sensor is fully registered.

Avoid unnecessary pollution of the global symbol namespace by
moving library functions in to a specific namespace and import
that into the drivers that make use of the functions.

Do not trust the fact that iio.h includes of.h which in turn includes
all the headers we are relying on.
The ultimate goal is to actually drop of.h from iio.h.

I2C doesn't use the buffers directly for DMA so there is no need

When sensor location is known, populate iio sysfs "label" attribute:
* "accel-base" : the sensor is in the base of the convertible (2-1)
device.
* "accel-display" : the sensor is in the lid/display plane of the
device.
* "accel-camera" : the sensor is in the swivel camera subassembly.
The non-standard |location| attribute is removed, the field |loc| in
cros_ec_sensors_core_state is removed.
It apply to standalone accelerometer as well as IMU (accelerometer +
gyroscope) and sensors where the location is known (light).

An odr_lock has been introduced to protect local accesses to the odr
internal cache and ensure the cached value always reflected the actual
value. Using the mlock() for this purpose is no longer needed, so let's
drop these extra mutex_lock/unlock() calls.

Letting the compiler remove these functions when the kernel is built
without CONFIG_PM_SLEEP support is simpler and less error prone than the
use of #ifdef based config guards.
Removing instances of this approach from IIO also stops them being
copied into new drivers.

The core module and type specific core modules are made up of
several files. There is no benefit in duplicating the MODULE_* macros
in each file so remove them.
Noticed whilst adding MODULE_IMPORT_NS() as I missed some files and
it still worked, making it clear not all of these blocks were needed.

So add an ACPI match table for that accordingly.

This patch makes I2C and SPI interface drivers for STMicroelectronics
sensor chips individually selectable via Kconfig.
The default is kept unchanged - I2C and SPI interface drivers are still
selected by default if the corresponding bus support is available.
However, the patch makes it possible to explicitly disable drivers
that are not needed for a particular target.

The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

Use the new EXPORT_RUNTIME_DEV_PM_OPS() macro. It allows the underlying
dev_pm_ops struct as well as the suspend/resume callbacks to be detected
as dead code in the case where CONFIG_PM is disabled, without having to
wrap everything inside #ifdef CONFIG_PM guards.
