Note the binding is st,lsm9ds1-imu. This device is effectively
two separate devices in the same package. (separate addreses,
chip selects etc) The magnetometer is already supported
as lsm9ds1-mag. imu may not be the best name but it's the best
that anyone has yet come up with for a gyro and accel part.

Add documentation for optional use of external clock. All devices
supported by this driver can work with an external clock in sync mode.
Another mode, called Pulse Per Second (PPS) is supported only by adis1649x
devices. The mode is selected by using the "clock-names" property.
The pin which is used as external clock input is selected by using a
custom optional property called "adi,ext-clk-pin". If this field is left
empty, DIO2 is assigned as default external clock input pin.

The bmi160 bindings say that the BMI160 requires level-triggered,
active-low interrupts, but it actually supports all interrupt types, so fix
the note to reflect that.

Jonathan writes:
1st round of IIO new device support, features and cleanups in the 4.20 cycle.
There is a merge commit in here to pull in regmap support for repeatedly
reading the same register (to read out FIFOs). Used by the adxl372 driver.
This will find uses elsewhere once we tidy up various drivers that are
effectively doing this and relying on not enabling regcache.
New device support
* Analog devices ADXL372 accelerometer
- new driver for this accelerometer including fifo and and interrupt support.
Follow up patches enforce trigger validation, add sampling frequency
control and filter bandwidth control. A later series added i2c support
to the existing SPI support.
* ST lsm6dsx
- rework and add support fo the LSM6DSO 6 axis mems sensor.
* Linear LTC 1660 DAC
- new driver supporting the LTC 1660 and LTC 1665 SPI DACs.
* Microchip mcp3911 ADC.
- new driver for this integrated analog front end and ADC.
* Qualcomm SPMI PMIC5 adc driver
- using the spmi framework, new driver and bindings for this ADC.
Follow up patch adds some missing channels.
Features
* ad5758
- support hard reset using a gpio (if provided).
* mpu6050
- Regulator support
* qcom-spmi-adc5
- Sanity check the channel numbers provided by DT to make sure the
driver actually knows about them.
* sc27xx
- give raw data for channel 20 as it's used on all known boards for
the headset which needs a custom converstion function. If it turns
out someone builds a board where this isn't true we will deal with it
when it happens.
- add ADC scale calibration.
* tsl2772
- support device tree binding to set the proximity led settings.
- regulator supprot.
- binding for apds9930 - trivial addition as register compatible with tsl2772.
Cleanups / Minor fixes
* adxl345
- supress a static checker warning but explicitly checking if the id
object is null.
* bh1750
- avoid CONFIG_PM_SLEEP checks.
- SPDX.
* bme680
- spelling mistake
- use clamp rather than open coding.
- white space and other similar fixes.
- rename MSK to MASK for clarifty and use GENMASK to specify them.
- use the FIELD_GET macro rather than a very odd accessor of dividing by
16 to get the shift.
- rework to share handing for oversampling of the various channels in a
unified way.
- check explicitly for val2 in write_raw function to ensure it is 0.
- drop some field defines that don't add anything.
* dpot-adc
- SPDX
* envelope detector
- SPDX
* isl29501
- fix an ancient compiler warning mostly because it results in much
nicer code.
* max30102
- mark switch fall throughs.
* max44000
- drop an unused variable.
* max512
- avoid CONFIG_PM_SLEEP checks.
* max5481
- use of_device_get_match_data rather than open coding it.
* max5821
- avoid CONFIG_PM_SLEEP checks.
* max9611
- explicity cast an enum to an integer to make it totally clear that
this is intended.
* mcp4018
- fix an inconsistent MODULE_LICENSE.
- use of_device_get_match_data rather than open coding it.
* mcp4531
- use of_device_get_match_data rather than open coding it.
- SPDX
* mcp4725
- avoid CONFIG_PM_SLEEP checks.
* mcp4922
- Fix error handling and prevent writing a negative to when setting the
output voltage.
* ms5611
- drop deprecated compatible strings without manufacturer from being
explicitly listed. They are handled anyway.
- SPDX
* multiplexer
- SPDX
* qcom-vadc
- fix inconsistent documentation for reg.
* ti-dac5571
- provide and of_match_table.
* treewide
- update Michael Hennerich's email address.
- Use %pOFn rather than device_node.name.
* documentation.
- tidy up a wrong kernel version for the introduction of the
position_relative ABI.

Pull staging and IIO updates from Greg KH:
"Here are the big staging/iio patches for 4.19-rc1.
Lots of churn here, with tons of cleanups happening in staging
drivers, a removal of an old crypto driver that no one was using
(skein), and the addition of some new IIO drivers. Also added was a
"gasket" driver from Google that needs loads of work and the erofs
filesystem.
Even with adding all of the new drivers and a new filesystem, we are
only adding about 1000 lines overall to the kernel linecount, which
shows just how much cleanup happened, and how big the unused crypto
driver was.
All of these have been in the linux-next tree for a while now with no
reported issues"

'interrupt-parent' is often documented as part of define bindings, but
it is really outside the scope of a device binding. It's never required
in a given node as it is often inherited from a parent node. Or it can
be implicit if a parent node is an 'interrupt-controller' node. So
remove it from all the binding files.

The mpu9250 is a SIP containing an mpu6500 and an ak8975. If this was all
there was too it there would be no need for explicit handling in the driver.
Arguably the bindings would also only reflect the presence of an mpu6500 with
the ak8975 hanging off it, as the kernel doesn't care that they are in one
package.
However, the WHOAMI value changes as well so best to add explicit support.

These bindings are somewhat lagging the state of the driver. The i2c-gate
bindings are documented elsewhere, but it seems sensible to at least have
an example and cross reference in here. SPI bindings will need to be the
subject of a future patch.

Old interface is kept for backward userspace compatibility and may be
