This got caught by the implicit fall through detection but is
a bug rather than missing marking.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
First set of new device support, features and cleanups for IIO in the 5.4 cycle
Note includes a merge from i3c tree to get support needed for stm_lsm6dsx driver
support for l3c devices. Done from immutable branch.
A counter subsystem patche in here as well.
Alongside the new device support (which is always good), Chuhong's work
on using devres managed APIs has cleaned up a number of drivers.
New device support
* adis16460
- New driver based on ADIS framework which needed addition of support
for cs_change_delay. Includes device tree binding.
* cros_ec
- Support fo the veyron-minnie which uses an older interface.
* lsm6dsx
- Support for LSM6DSTR-C gyro + magnetometer sensor (new IDs mainly)
- Support for ISM330DHCX acc + gyro sensor (extensive rework needed!)
* Maxim 5432
- New driver support MAX5432-MAX5435 family of potentiometers.
* noa1305
- New driver for this ON Semiconductor Ambient light sensor.
Features and cleanups
* tree wide
- Drop error prints after platform_get_irq as already prints errors
internally if any occur.
* docs
- Document mounting matrix.
- Fix a missing newline at end of file.
* ad2s1210
- Switch to device managed APIs for all of probe and drop explicit remove.
* ad7192
- Add of_device_id array to explicity handling DT bindings.
* ad7606
- Lots of rework leading to support for software configure modes in ad7616
parts.
- Debugfs register access support.
* am2315
- Switch to device managed APIs for all of probe and drop explicit remove.
* apds9960
- Typo in module description.
* cm36651
- Convert to i2c_new_dummy_device.
- Swithc to device managed APIs for all of probe adn drop explicit remove.
* cros_ec
- Calibscale support for accel, gyro and magnetometer.
- Tidy up some error codes to return the error from the stack rather than
-EIO.
- Determine protocol version.
- Add a sign vector to the core to fix sensor rotation if necessary.
Cannot just be done with mount matrix as already in use in many devices.
- Tidy up INFO_SCALE being in both the separate and shared lists.
- Drop a lot of dplicate code from the cros-ec-accel-legacy driver
and use the core provided code instead.
- Make frequency range available to userspace.
* counter / ftm-quaddec
- Switch to device managed APIs for all of probe adn drop explicit remove.
* hdc100x
- Switch to device managed APIs for all of probe and drop explicit remove.
* hi8435
- Use gpiod_set_value_cansleep as we don't care here and there is a
board out there where it needs to sleep.
- Switch to device managed APIs for all of probe and drop explict remove.
* hp03
- Convert to i2c_new_dummy_device.
* maxim thermocouple
- Switch to device managed APIs for all of probe and drop explicit remove.
* mmc35240
- Fix typo in constant naming.
* mpu6050
- Use devm_add_action_or_reset in place of explicit error handling.
- Make text in Kconfig more explicit about which parts are supported.
* mxc4005
- Switch to device managed APIs for all of probe and drop explicit remove.
* pms7003
- Convert device tree bindings to yaml.
- Add a MAINTAINERS entry
* sc27xx
- Introduce a local struct device *dev pointer to avoid lots of deref.
- Use devm_add_action_or_reset in place of explicit error handling.
* sca3000
- Typo fix in naming.
* si1145
- Switch to device managed APIs for all of probe and drop explicit remove.
* st_sensors
- Lots of rework to enable switch to regmap.
- Regmap conversion at the end.
- Tidy up some inconsistencies in buffer setup ops.
- Tidy up an oddity by dropping get_irq_data_ready function in favour
of direct access.
- Stop allocating buffer in buffer enable in favour of just embedding
a large enough constant size buffer in the iio_priv accessed structure.
* st_lsm6dsx
- l3c device support (LSM6DSO and LSM6DSR)
- tidy up irq return logic which was strangely written.
- fix up an ABI quirk where this driver used separate scale
attributes, even though they were always shared by type.
* stk33xx
- Device tree bindings include manufacturer ID.
* stm32-adc
- Add control for supply to analog switches including DT bindings.
* stm32 timer
- Drop the quadrature mode support. Believed there were no users so
take this opportunity to drop this unwanted ABI.
* tsl2772
- Switch to device mangage APIs for all of probe and drop explicit remove.
- Use regulator_bulk_* APIs to reduce repitition.
* veml6070
- Convert to i2c_new_dummy_device.

The max9611 driver reads the die temperature at probe time to validate
the communication channel. Use the actual read value to perform the test
instead of the read function return value, which was mistakenly used so
far.
The temperature reading test was only successful because the 0 return
value is in the range of supported temperatures.

in_accel_x_scale, in_accel_y_scale and in_accel_z_scale are always
the same. The scale is still defined to be in "info_mask_separate".
Userspace (iio-sensor-proxy and others) is not used to that and only
looks for "in_accel_scale" for the scaling factor to apply.
Change IIO_CHAN_INFO_SCALE from being separate in all channel to be
shared by type.
This removes in_accel_x_scale, in_accel_y_scale and in_accel_z_scale and
makes available in_accel_scale.
This is an ABI change, but hopefully in the 'no one will notice'
category. The cleanup in interface is worth the small risk that
there is a custom script out there somewhere that this will break.

Use devm_add_action_or_reset to call tsl2772_chip_off
when the device is removed.
This also fixes the issue that the chip is turned off
before the device is unregistered.
Not marked for stable as fairly hard to hit the bug and
this is in the middle of a set making other cleanups
to the driver. Hence will probably need explicit backporting.

This patch is trying to cleanup for good the buffers operation functions.
There is no need of using preenable, all can be done into
postenable. Let's also use logical sequence of operations as
already done in accel driver.
Finally also rename the goto label using operation to perform and not
where it fails.
Not stable material as not fixing a 'bug' but rather bringing the
driver in line with general 'patterns' to allow a subsystem wide
cleanup.

Support for ad7616 running in software was added. In order

Oversampling and input ranges are now configured in corresponding
registers. Ad7616 has multiple scale options when it is configured
in software mode.
Also, in order to support multiple devices in software mode, the spi
calculation of registers address must be generic. Because
the length of address and bit which specifies the read/write operation is
different for every device, calculation of address was made generic.

The ADIS16460 device is a complete inertial system that includes a triaxial
gyroscope and a triaxial accelerometer. It's more simplified design than
that of the ADIS16480, and does not offer the triaxial magnetometers &
pressure sensors. It does also have a temperature sensor (like the
ADIS16480).
Since it is part of the ADIS16XXX family, it re-uses parts of the ADIS
library.
Naturally, the register map is different and much more simplified than the
ADIS16480 subfamily, so it cannot be integrated into that driver. A major
difference is that the registers are not paged.
One thing that is particularly special about it, is that it requires a
higher delay between CS changes (i.e. when CS goes up, the spec recommends
that it be brought down after a minimum of 16 uS).
Other ADIS chips require (via spec) a minimum of 2 uS between CS changes.
The kernel's 10 uS default should be fine for those other chips; they
haven't been tested with lower CS change delays yet.

The ADIS16460 requires a higher delay before the next transfer. Since the
SPI framework supports configuring the delay before the next transfer, this
driver will become the first user of it.
The support for this functionality in ADIS16460 requires an addition to the
ADIS lib to support the `cs_change_delay` functionality from the SPI
subsystem.

Use device-managed APIs to simplify the code.
The remove function is redundant now and can
be deleted.
