First set of new device support, cleanups and features for IIO in the 5.9 cycle
Some new devices, but particularly good this time is the core rework coming
from Alexandru. Some of this has been in Analog's tree a long time, but other
parts are motivated by closing down common mistakes in new drivers.
Changes since first try at this pull request:
* Add missed patch to actually remove iio_priv_to_dev and as a result
also drop a few ingenic patches that need to be updated to take this
into account.
* Fix an ordering issue int he pollfunc attach in the core rework.
New device support
* qcom pmic7 adc
- New driver using common qcom-vadc library. Some associated cleanups and
refactors.
* invensense icm42600
- New driver supporting icm42600, icm42602, icm42605 and icm42622 via i2c
or spi. These are all 6 axis IMUs with gyro and accelerometers.
Driver supports buffered modes using the hardware fifo and interpolation
for accurate timestamps.
* sensirion scd30
- New driver for this carbon dioxide sensor including i2c and serial
interfaces + bindings.
Features
* ak8975
- Add reset gpio support.
* bma400
- Support SPI.
* bmc150
- Document and add support for bmc156b and bmm150b, tidy up _magn endings.
* bmi160
- Regulator and mount matrix support.
* mxc4005
- Add ID for mxc6655
* rockchip-saradc
- Triggered buffer support.
DT bindings
* qcom spmi-vadc converted to yaml + pmic7 bindings
* ak8975 tidy up and convert to yaml + add reset-gpio binding
* ingenic-adc -convert to yaml.
Core rework all carried through by Alexandru Ardelean.
* Assign parent device in the core rather than every driver. A few devices
need to provide specific non standard parents, so there is support for
overriding.
* Start to take parts of struct iio_dev opaque to the drivers.
This will be a long term job, but should reduce the number of drivers
we get that use parts that are currently only 'internal' by documentation.
* Move attach and detach of pollfunc to the core. Every triggered buffer
using driver had to do the same thing, so lets do it in the core. The
hard part here was getting all the drivers into canonical form so there
would be no functional changes in this final patch. That's taken quite
a lot of work over last couple of cycles!
Cleanups and minor fixes.
* docs
- Improve IIO_CONCENTRATION channel type description in ABI docs.
- Drop doubled word cases.
- Http to Https conversion.
* core
- Make iio_device_get_drvdata take a const struct iio_dev * avoiding some
nasty casts.
* ADCs
- Drop lots of users of of_match_ptr macro, includes of mod_devicetable.h
and CONFIG_OF protections. These prevent use of ACPI PRP0001 with these
drivers and get coppied into lots of new drivers.
* ad5380
- Constify iio_chan_spec_ext_info
* ad5592r
- Constify iio_chan_spec_ext_info
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* ad8366
- Make gpio optional as doesn't matter if its there or not.
* adis16480
- Use irq types instead of the flags.
* atlas-ezo-sensor
- Minimize scope of ret variable.
* at91-adc
- Add COMPILE_TEST dependency to driver to improve build coverage.
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* at91-sama5d2
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
- Drop Ludovic as a co-maintaienr.
* cros_ec
- Reapply the range after resume.
- Add a read only frequency entry for legacy version.
- Typo fixes
* hts221
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)

Another round of 'allOf' removals that came in this cycle.
json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.
This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.

On the staging driver front, again, nothing noticable. No new

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.

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.

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.
