Jonathan writes:

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.
+
+  Specifications about the devices can be found at:
+    https://prod-edam.honeywell.com/content/dam/honeywell-edam/sps/siot/en-us/
