7cf15f4275 iio: Switch i2c drivers back to use .probe() 
After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

598e971fab iio: st_sensors: Add ACPI support for lsm303d to the LSM9DS0 IMU driver 
The lsm303d can be found as ACCL0001 on various Lenovo devices,
including the Lenovo Yoga Tablet 2 1051-F, where I tested this
patch.

Dropped SPI support as per discussion in thread linked below.

c0f68439ae iio: st_sensors: Add lsm303d support to the LSM9DS0 IMU driver 
The lsm303d is basically the lsm9ds0 without the gyroscope
(which the LSM9DS0 IMU driver doesn't handle), as far as I
can tell.

9e855d77b1 iio: st_sensors: core and lsm9ds0 switch to devm_regulator_bulk_get_enable() 
These drivers only turns the power on at probe and off via a custom
devm_add_action_or_reset() callback. The two regulators were handled
separately so also switch to bulk registration.
The new devm_regulator_bulk_get_enable() replaces all this boilerplate
code.

26b2ec2e9a iio: st_sensors: don't always auto-enable I2C and SPI interface drivers 
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.

b42baaa3e2 iio: st_lsm9ds0: Make use of the helper function dev_err_probe() 
When possible use dev_err_probe help to properly deal with the
PROBE_DEFER error, the benefit is that DEFER issue will be logged
in the devices_deferred debugfs file.
Using dev_err_probe() can reduce code size, and the error value
gets printed.

e426965154 iio: st_sensors: remove reference to parent device object on st_sensor_data 
The idea behind it, is that all devm_ calls in ST sensors are bound to the
parent device object.

However, the reference to that object is kept on both the st_sensor_data
struct and the IIO object parent (indio_dev->dev.parent).

This change only adds a bit consistency and uses the reference stored on
indio_dev->dev.parent, to enforce the assumption that all ST sensors' devm_
calls are bound to the same reference as the one store on st_sensor_data.

6b658c31bb iio: st_sensors: remove all driver remove functions 
At this point all ST driver remove functions do iio_device_unregister().
This change removes them from them and replaces all iio_device_register()
with devm_iio_device_register().

This can be done in a single change relatively easy, since all these remove
functions are define in st_sensors.h.

9c6cd755b5 iio: st-sensors: Remove some unused includes and add some that should be there 
The st-sensors drivers have changed in structure over time, and includes
have not always kept up with this.  Let's bring them back to nearer
the ideal.

Identified with the  include-what-you-use tool and careful checking of
its suggestions.

Note I haven't been particularly aggressive here, so this is just the
cases where the include obviously isn't needed rather than the more
subtle corners.

Note I took the opportunity to add mod_devicetable.h as I generally
prefer to see that when acpi or of match tables are present.

6731ca3999 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.
