Second set of new device support, features and minor fixes for IIO in the 5.6 cycle
Just a small set this time.
As we are very near the merge window, I've rolled a few fixes in here
rather than adding noise just before release. A short delay here will
do little harm.
New device support
* adis16480
- Add support for adis16490. After earlier rework this is simple ID plus
chip info.
Features
* kxcjk1013
- mount matrix support.
* lsm_6dsx
- mount matrix support.
Cleanups / minor or late breaking fixes
* ad7124
- add support to ad-sigma-delta and use it in this driver to allow
the the interrupt type to be IRQF_TRIGGER_LOW unlike most other devices
using this framework.
* adis
- use delay structure now available in SPI to handle transfer delays
- introduce a timeouts structure to allow support of new devices
* ak8975
- drop platform data support. No one is using it and it adds complexity.
- use device_get_match_data rather than open coding much the same thing.
* dht11
- drop meaningless todo
* at91-samad2_adc
- switch to dma_request_chan
* altas-sensor
- add a helper function to compute number of channels. Needed for new device
support that is under review.
* bma400
- add a lower bound check on scale.
* inv_mpu6050
- add support for temperature data in the fifos for all chips.
- support an odd situation where a board supports only interrupt triggering
on both edges.
* st_lsm6dsx
- check and handle potential error return.
* st_sensors
- fix some values for the LSM9DS0 which is ever so slightly different from
other devices using the same whoami value.
- switch over to generic functions from dt ones, avoiding need for separate
ACPI support.
* stm32-adc
- switch to dma_request_chan
- suppress an error print in deferred probe case.
* stm32-dac
- drop private data structure element for reset controller as only used in
probe.
- reflect more cleanly that the reset controller is optional whilst ensuring
that if is specified any errors are caught.
* stm32-dfsdm
- switch to dma_request_chan
- fix missing application of formatting to single conversions.
- ensure the sampling rate is updated when the oversampling ratio is changed.

Use devm_reset_control_get_optional_exclusive() instead of
devm_reset_control_get_exclusive() as reset controller is optional.
Nevertheless if reset controller is expected but reports an
error, propagate the error code to the caller. In such case
a nice error trace is emitted unless we're deferring the probe
operation.

staging: wfx: with multiple vifs, force PS only if channels differs
When multiple vif are in use (the only supported configuration is one
station and one AP), the driver force power save flag on station.
This behavior allows the station to leave the station channel and make
its business on AP channel.
However, this has a big impact on station performances (especially since
only legacy PS is supported).
When both vifs use the same channel, it is not necessary to keep this
restriction. This greatly improve station performances.

staging: wfx: simplify hif_set_output_power() usage
Hardware API use 10th of dBm for output power unit. Upper layers should
use same units than mac80211 and the conversion should be done by low
level layer of the driver (hif_set_output_power())
In add, current code of hif_set_output_power() use a __le32 while the
device API specify a specific structure for this.

staging: wfx: send rate policies one by one
Rate policies (aka. tx_rate_retry_policy in hardware API) are sent to
device asynchronously from tx requests. So, the device maintains a list
of active rate policies and the tx requests only reference an existent
rate policy.
The device API allows to send multiple rate policies at once. However,
this property is very rarely used. We prefer to send rate policies one
by one and simplify the architecture.

The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure
