A call to pm_runtime_put_noidle() doesn't match any call that would
result in a get(). It is safe because runtime pm core protects against
the reference counter going 0, but it makes it harder to understand the
code.
Whilst here use pm_runtime_resume_and_get() to tidy things up.
The Coccinelle script didn't get this one due to more complex code
structure.

The KX023-1025 accelerometer [1] seems to be some mixture of
KXCJK and KXTF9. It has the motion interrupt functionality from KXCJK
but also the tap detection from KXTF9, and a lot more functionality.
The configuration register map seems fairly different at first,
but actually all register bits used by the kxcjk-1013 driver are
available at the same bit positions on KX023-1025. It's just quite
misleading because:
1. The registers have entirely different names and are at different
addresses, but the bits are mostly named the same (and mean the same).
2. There are many more registers and bits used that are reserved on KXCJK
to enable additional functionality.
Ignoring all additionally available functionality for now, the KX023
works just fine after setting up the struct with the correct register
addresses. The only difference that needs to be handled additionally
is that the KX023 supports two configurable interrupt lines (INT1/2).
For now only INT1 is supported so we route all interrupts used by
the driver there.

Most Kionix accelerometers seem to use fairly consistent register bits,
but the register addresses are not necessarily the same. This is already
partially the case for the KXTF9 (added in commit 1540d0106b
("iio: accel: kxcjk1013: add support for KXTF9")), which has some
registers at different addresses.
However, it's even much worse for the KX023-1025. All register bits
used by the kxcjk-1013 driver seem to be fully compatible with KX023,
but it has most registers at totally different addresses.
In preparation to add support for KX023-1025, move the fixed register
addresses into a struct so we can change them for KX023 more easily.

During commit 067fda1c06 ("iio: hid-sensors: move triggered buffer
setup into hid_sensor_setup_trigger"), the
iio_triggered_buffer_{setup,cleanup}() functions got moved under the
hid-sensor-trigger module.
The above change works fine, if any of the sensors get built. However, when
only the common hid-sensor-trigger module gets built (and none of the
drivers), then the IIO_TRIGGERED_BUFFER symbol isn't selected/enforced.
Previously, each driver would enforce/select the IIO_TRIGGERED_BUFFER
symbol. With this change the HID_SENSOR_IIO_TRIGGER (for the
hid-sensor-trigger module) will enforce that IIO_TRIGGERED_BUFFER gets
selected.
All HID sensor drivers select the HID_SENSOR_IIO_TRIGGER symbol. So, this
change removes the IIO_TRIGGERED_BUFFER enforcement from each driver.

Commit 2e2366c2d1 ("iio: cros_ec: unify hw fifo attributes into the core file")
should be reverted as it set buffer extended attributes at
the wrong place. However, to revert it will requires to revert more
commits:
commit 165aea80e2 ("iio: cros_ec: use devm_iio_triggered_buffer_setup_ext()")
commit 21232b4456 ("iio: buffer: remove iio_buffer_set_attrs() helper")).
and we would still have conflict with more recent development.
commit ee708e6baa ("iio: buffer: introduce support for attaching more IIO buffers")
Instead, this commit reverts the first 2 commits without re-adding
iio_buffer_set_attrs() and set the buffer extended attributes at the
right place:
1. Instead of adding has_fw_fifo, deduct it from the configuration:
- EC must support FIFO (EC_FEATURE_MOTION_SENSE_FIFO) set.
- sensors send data a regular interval (accelerometer, gyro,
magnetomer, barometer, light sensor).
- "Legacy accelerometer" is only present on EC without FIFO, so we don't
need to set buffer attributes.
2. devm_iio_triggered_buffer_setup_ext() does not need to be called when
EC does not support FIFO, as there is no FIFO to manage.
3. Use devm_iio_triggered_buffer_setup_ext() when EC has a FIFO to
specify the buffer extended attributes.

iio_device_attach_buffer() are simple to convert to

This change does that; the unwind order is preserved.
What is important, is that the devm_iio_kfifo_buffer_setup() be called
after the indio_dev->modes is assigned, to make sure that
INDIO_BUFFER_SOFTWARE flag is set and not overridden by the assignment to
indio_dev->modes.
Also, the INDIO_BUFFER_SOFTWARE has been removed from the assignments of
'indio_dev->modes' because it is set by devm_iio_kfifo_buffer_setup().

Some BOSC0200 acpi_device-s describe two accelerometers in a single ACPI
device. Normally we would handle this by letting the special
drivers/platform/x86/i2c-multi-instantiate.c driver handle the BOSC0200
ACPI id and let it instantiate 2 bmc150_accel type i2c_client-s for us.
But doing so changes the modalias for the first accelerometer
(which is already supported and used on many devices) from
acpi:BOSC0200 to i2c:bmc150_accel. The modalias is not only used
to load the driver, but is also used by hwdb matches in
/lib/udev/hwdb.d/60-sensor.hwdb which provide a mountmatrix to
userspace by setting the ACCEL_MOUNT_MATRIX udev property.
Switching the handling of the BOSC0200 over to i2c-multi-instantiate.c
will break the hwdb matches causing the ACCEL_MOUNT_MATRIX udev prop
to no longer be set. So switching over to i2c-multi-instantiate.c is
not an option.
Changes by Hans de Goede:
-Add explanation to the commit message why i2c-multi-instantiate.c
cannot be used
-Also set the dev_name, fwnode and irq i2c_board_info struct members

Some 360 degree hinges (yoga) style 2-in-1 devices use 2 KXCJ91008-s
to allow the OS to determine the angle between the display and the base
of the device, so that the OS can determine if the 2-in-1 is in laptop
or in tablet-mode.
On Windows both accelerometers are read by a special HingeAngleService
process; and this process calls a DSM (Device Specific Method) on the
ACPI KIOX010A device node for the sensor in the display, to let the
embedded-controller (EC) know about the mode so that it can disable the
kbd and touchpad to avoid spurious input while folded into tablet-mode.
This notifying of the EC is problematic because sometimes the EC comes up
thinking that device is in tablet-mode and the kbd and touchpad do not
work. This happens for example on Irbis NB111 devices after a suspend /
resume cycle (after a complete battery drain / hard reset without having
booted Windows at least once). Other 2-in-1s which are likely affected
too are e.g. the Teclast F5 and F6 series.
The kxcjk-1013 driver may seem like a strange place to deal with this,
but since it is *the* driver for the ACPI KIOX010A device, it is also
the driver which has access to the ACPI handle needed by the DSM.
Add support for calling the DSM and on probe unconditionally tell the
EC that the device is laptop mode, fixing the kbd and touchpad sometimes
not working.

are planning to add support for multiple IIO buffers per IIO device, the
issue has to do with:
1. Accessing 'indio_dev->buffer' directly (as is done with
'iio_buffer_set_attrs(indio_dev->buffer, <attrs>)').
2. The way that the buffer attributes would get handled or expanded when
there are more buffers per IIO device. Current a sysfs kobj_type expands
into a 'device' object that expands into an 'iio_dev' object.
We will need to change this, so that the sysfs attributes for IIO
buffers expand into IIO buffers at some point.
Right now, the current IIO framework works fine for the
'1 IIO device == 1 IIO buffer' case (that is now).

Second set of features and cleanups for IIO in 5.10
We have a couple of changes that apply to large sets of drivers, so
I have grouped those to keep this short.
There are a few late breaking fixes in here that can wait for the
merge window.

Features
--------
* adxrs290
- Add triggered buffer support and expose data ready signal as a possible
trigger. Includes updating bindings.
- Add debugfs hooks for register access.
* mlx90632
- Add a clear user interface to override the measured ambient temperature.
* vl53l0x
- Add IRQ support including dt bindings.
Cleanups and minor fixes
------------------------
(groups)
Replace mlock with local lock:
* adf4350
* exynos-adc
* fls-imx25-gcq
* stm32-dac
devm use to simplify probe error handling and remove functions.
* adis16201
* adis16203
* adis16209
* adis16240
* adis16136
* adis16260
* adis16400
* adis16460
* adis16480
* adis library - drop unused adis_setup_buffer_and_trigger()
of_match_ptr removal and incorrect ACPI binding removal
of_match_ptr() rarely makes sense in an IIO driver as space saving
is trivial and it breaks ACPI PRP0001 based instantiation.
Mostly this series is about removing examples that get copied into new
drivers.
