Introduce ABI documentation for new modifiers used for reporting rotations
expressed as euler angles (i.e. yaw, pitch, roll).
It looks like we have some unit inconsistency along various IIO modifiers:
it seems that incli is in deg, angl is in radians and rot isn't documented,
but at least the adis16209 driver has rot in deg.
Here we use deg (so angl is the only one using radians).

Add IIO_MOD_LINEAR_X, IIO_MOD_LINEAR_Y and IIO_MOD_LINEAR_Z modifiers to te
IIO core, which is preparatory for adding the Bosch BNO055 IMU driver.
Bosch BNO055 IMU can report raw accelerations (among x, y and z axis) as
well as the so called "linear accelerations" (again, among x, y and z axis)
which is basically the acceleration after subtracting gravity and for which
those new modifiers are for.

The DPS310 chip has been observed to get "stuck" such that pressure
and temperature measurements are never indicated as "ready" in the
MEAS_CFG register. The only solution is to reset the device and try
again. In order to avoid continual failures, use a boolean flag to
only try the reset after timeout once if errors persist.

By default the driver was always setting the RANGE bit which means that
the analog input goes from 0 to VREF. However, we might want to have 0
to 2xVREF. This change adds a new Firmware property to allow for the
extended range while keeping the default behavior if nothing is provided.

Some of the supported devices have 4 or 2 LSB trailing bits that should
not be taken into account. Hence we need to shift these bits out which
fits perfectly on the scan type shift property. This change fixes both
raw and buffered reads.

Set the iio device's name based on the chip used for the
LTC2499 only. The most common way for IIO clients to interact
with a device is to address it based on it's name. By using
the dev_name() function, the name will be set based on a
i2c_client's kobj name, which has the format i2c_instance-i2c_address
(1-0076 for example). This is not ideal, since it makes a
requirement for userspace to have knowledge about the hardware
connections of the device.
The name field is set to NULL for the LTC2497 and LTC2496, so
that the old name can kept as it is, since changing it will
result in an ABI breakage.

After the result of the previous conversion is read the chip
automatically starts a new conversion and doesn't accept new i2c
transfers until this conversion is completed which makes the function
return failure.
So add an early return iff the programming of the new address isn't
needed. Note this will not fix the problem in general, but all cases
that are currently used. Once this changes we get the failure back, but
this can be addressed when the need arises.

1st set of IIO new device support, features and cleanup for 6.1
This includes Nuno Sa's work to move the IIO core over to generic firmware
properties rather than having DT specific code paths. Combined with Andy
Shevchenko's long term work on drivers, this leaves IIO in a good state for
handling other firmware types.
New device support
- liteon,ltrf216a
* New driver and dt bindings to support this Light sensor.
- maxim,max11205
* New driver for this 16bit single channel ADC.
- memsensing,msa311
* New driver for this accelerometer. Includes a string helper for read/write.
- richtek,rtq6056
* New driver and dt binding to support this current monitor used to measure
power usage.
- yamaha,yas530
* Support the YAS537 variant (series includes several fixes for other parts
and new driver features).
Staging graduation
- adi,ad7746 CDC. Cleanup conducted against set of roadtest tests using
the posted RFC of that framework.
Features
- core
* Large rework to make all the core IIO code use generic firmware properties.
Includes switching some drivers over as well using newly provided
generic interfaces and allowing removal of DT specific ones.
* Support for gesture event types for single and double tap. Used in
bosch,bma400.
- atmel,at91-sama5d2
* Add support for temperature sensor which uses two muxed inputs to estimate
the temperature.
* Handle trackx bits of EMR register to improve temp sampling accuracy.
* Runtime PM support.
- liteon,ltrf216a
* Add a _raw channel output to allow working around an issue with
differing conversions equations that breaks some user space controls.
- mexelis,mlx90632
* Support regulator control.
- ti,tsc2046
* External reference voltage support.
Clean up and minor fixes
- Tree-wide
* devm_clk_get_enabled() replacements of opencoded equivalent.
* Remaining IIO_DMA_MINALIGN conversions (the staging/iio drivers).
* Various minor warning and similar cleanup such as missing static
markings.
* strlcpy() to strscpy() for cases where return value not checked.
* provide units.h entries for more HZ units and use them in drivers.
- dt-bindings cleanup
* Drop maintainers listss where the email address is bouncing.
* Switch spi devices over to using spi-peripheral.yaml
* Add some missing unevaluatedProperties / additionalProperties: false
entries.
- ABI docs
* Add some missing channel type specific sampling frequency entries.
* Add parameter names for callback parameters.
- MAINTAINERS
* Fix wrong ADI forum links.
- core
* lockdep class per device, to avoid an issue with nest when one IIO
device is the consumer of another.
* White space tweaks.
- asc,dlhl60d
* Use get_unaligned_be24 to avoid some unusual data manipulation and masking.
- atmel,at91-sama5d2
* Fix wrong max value.
* Improve error handling when measuring pressure and touch.
* Add locks to remove races on updating oversampling / sampling freq.
* Add missing calls in suspend and resume path to ensure state is correctly
brought up if buffered capture was in use when suspend happened.
* Error out of write_raw() callback if buffered capture enabled to avoid
unpredictable behavior.
* Handle different versions having different oversampling ratio support and
drop excess error checking.
* Cleanup magic value defines where the name is just the value and hence
hurts readability.
* Use read_avail() callback to provide info on possible oversampling ratios.
* Correctly handle variable bit depth when doing oversampling on different
supported parts. Also handle higher oversampling ratios.
- fsl,imx8qxp
* Don't ignore errors from regulator_get_voltage() so as to avoid some
very surprising scaling.

This harmless print provides a very easy way of knowing
if the modem is detected properly during probing.
Promote it to an informational print so no hassle is required
enabling kernel debugging info to obtain it.
The rationale here is that:
On a lot of low-storage embedded devices, extensive kernel
debugging info is not always present as this would
increase it's size to much causing partition size issues.

Add a driver name for the D5005 BMC secure update driver. Different
driver names are used for the N3000 and D5005 devices because future
changes will add conditional code based on the device type (N3000
vs D5005). This change enables D5005 secure updates of BCM images,
BMC firmware, static-region images, etc.

kmap() is being deprecated in favor of kmap_local_page().
There are two main problems with kmap(): (1) It comes with an overhead as
the mapping space is restricted and protected by a global lock for
synchronization and (2) it also requires global TLB invalidation when the
kmap’s pool wraps and it might block when the mapping space is fully
utilized until a slot becomes available.
With kmap_local_page() the mappings are per thread, CPU local, can take
page faults, and can be called from any context (including interrupts).
It is faster than kmap() in kernels with HIGHMEM enabled. Furthermore,
the tasks can be preempted and, when they are scheduled to run again, the
kernel virtual addresses are restored and still valid.
Since its use in xilinx_sdfec.c is safe, replace kmap()i / kunmap() with
kmap_local_page() / kunmap_local().

Pages in an array are mapped in a loop but, after the code is done with
the virtual addresses, these pages are never unmapped.
Therefore, call kunmap() to unmap pages[i].
