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.

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.

Follow up patch adds some missing channels.
Features

- support hard reset using a gpio (if provided).
* mpu6050

* 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.

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.
Note, you will have a merge problem with a device tree IIO file and the
MAINTAINERS file, both resolutions are easy, just take all changed.
There will be a skein file merge issue as well, but that file got
deleted so just drop that.

'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
