1st set of IIO new device support, features and cleanup for the 6.5 cycle.

New device support
- honeywell,mprls0025pa
* New driver and dt-bindings for this series of pressure sensors.
- invensense,mpu6050
* Add support for ICM 20600 IMU (ID, bindings and device data).
- melexis,mlx90614
* Add support for mlx90615 Infra Red Thermometer after driver cleanup
and refactoring to support the differences in this device.
- renesas,x9250
* New driver and bindings for this quad potentiometer.
- rockchip,saradc
* Add support for RK3588. Also included is a bunch of refactoring and
cleanup for that driver.
- rohm,bu27008
* New driver bindings etc for this 5 photodiode color sensor.
- st,lsm9ds0/st,st-sensors
* ID added for LSM303D accelerometer and magnetometer including ACPI binding.
- ti,opt4001
* New driver and bindings for this ambient light sensor.

Features
- core
* Introduce iio_validate_own_trigger() for cases where a driver can only
consumer a trigger it registered (detected via same parent device).
Use it in the kionix,kx022a driver and new rohm,by27008 driver.
- dynaimage,al3320a
* ACPI binding CALS0001 seen on Lenovo Yoga Table 2 devices.
- kionix,kx002a
* Enable asynchronous probe.
- rohm,bu27034
* Enable asynchronous probe.
- ti,tmp006
* Explicit support for DT including binding documentation.

Cleanups, minor fixes and misc improvements.
- treewide
* Switch I2C drivers from probe_new() back to probe() - part of the
long process of getting rid of a parameter from probe()
* Various whitespace and typo fixes not otherwise called out.
- core
* industrialio-buffer,Style cleanup.
* Add documentation to extend_name field of struct iio_chan_spec to
direct people using it towards the label infrastructure instead.
extend_name was a design mistake a long time back so directly people
away from it may be useful.
- adi,ad7606
* Add HAS_IOPORT dependency to prepare for some Kconfig changes.
- bosch,bma400
* Drop pointless print of ret in a dev_err_probe() message.
- invensense,icm42600
* Rework timestamp handling to reduce jitter.
- mediatek,mt7986-auxdac
* Add DT binding for this part.
- qcom,spmi-vadc
* Allow for 1/16th prescaling used on a few devices.
* Various changes to channel labeling and naming, including dropping
use of fwnode_name which generates odd channel names. Small ABI
change as a result, but not thought to be a problem for users of this
platform.
- st,lsm6dsx
* dt-binding: Use common schema for mount-matrix via a reference.
- st,stm32
* Add a debug print for when legacy channel config is used.
- ti,palmas-adc
* Drop unused i2c.h include.

* tag 'iio-for-6.5a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (59 commits)

+description: |
+  Honeywell pressure sensor of model mprls0025pa.
+
+  This sensor has an I2C and SPI interface. Only the I2C interface is
+  implemented.
+
+  There are many models with different pressure ranges available. The vendor
+  calls them "mpr series". All of them have the identical programming model and
+  differ in the pressure range, unit and transfer function.
+
+  To support different models one need to specify the pressure range as well as
+  the transfer function. Pressure range needs to be converted from its unit to
+  pascal.
+
+  The transfer function defines the ranges of numerical values delivered by the
+  sensor. The minimal range value stands for the minimum pressure and the
+  maximum value also for the maximum pressure with linear relation inside the
+  range.
