To keep this description manageable I have called those out in their own section rather than per driver. Particularly pleased to see the long running AFE precision series going in this cycle. Series includes some late breaking fixes. New device support * adi,ada4250 amplifier - New driver and dt bindings for this programmable gain amplifier. * adi,admv1014 microwave down-converter - New driver, dt bindings and some device specific ABI that may be generalized as more drivers for devices similar to this are added. * adi,admv4420 K Band down-converter. - New driver and dt bindings. * adi,adxl367 accelerometer driver. - New driver, dt-bindings + some new IIO ABI definitions to support reference magnitude events where an estimate of the acceleration due to gravity has been removed. - A few fixes as follow up patches. * adi,ltc2688 DAC with toggle and dither modes. - New driver and bindings. Includes some new driver specific (for now) ABI for handling toggle mode and the addition of a dither waveform to the DAC output. * AFE (analog front end) add support for additional types of analog device in front of an ADC. - RTD temperature sensors with dt bindings. - Temperature transducers wit dt bindings. - Related cleanup and features listed in other sections below. * maxim,ds3502 potentiometer. - Add support to ds1803 driver which required significant rework. * mediatek,mt2701-auxadc driver - Add mediatek,mt8186-auxadc - id table and chip specific info only. * semtech,sx9324, semtech,ax9360 - Substantial refactoring of sx9310 to extract core logic for reuse into a separate module - New driver using this supporting sx9324 proximity sensors. - New driver using this supporting sx9360 proximity sensors. * silan,sc7a20 - Compatible with the st,lis2dh (or nearly anyway) so add ID and chip specific info to enable support. Also silan vendor ID added for dt-bindings. Staging graduation * adi,ad7280a monitoring ADC for stacked lithium-ion batteries in electric cars and similar. - Substantial rework of driver required to bring inline with current IIO best practice. An unusual device in IIO so some interesting features we may see more of in future. Multiple driver/core cleanup - Use sysfs_emit() in simple locations where there is no path to change to various core created attributes. - Trivial white space fixes around inconsistency between space after { and before } in id tables. - Introduce new handling for fractional types to avoid repeated similar implementations. Use this in 3 drivers. Note this is also targeted at future use in the AFE driver and was motivated by discussions around the precision related work on that driver. - of related header cleanups - drop of*.h and add mod_devicetable.h as appropriate. - Move a number of symbol exports into IIO_* namespaces. Two categories, 1) Library used by multiple drivers e.g. st_sensors 2) Core driver module exporting functions used by bus specific modules. A few related cleanups in this set. - Switch from CONFIG_PM_* guards to new DEFINE_SIMPLE_DEV_PM_OPS() and similar to simplify drivers and take advantage of these new macros allowing the compiler to do the job or removing unused code without the need for __maybe_unused markings. Conversion of other drivers to these new macros ongoing. Features * adi,adf4350 - Switch from of specific to generic device properties enabling use with other firmware types. * adi,adx345 - Switch from of specific to generic device properties. - Add ACPI ID ADS0345 - Related driver cleanup. * adi,hmc425a - Switch from of specific to generic device properties. * afe analog rescaler driver - Wider range of types supported for scale. - Support offset. - Kunit tests. * atlas,ezo-sensor - Convert from of to device properties. * fsl,mma8452 - Support mount matrix. * infineon,dps310: - Add ACPI ID IFX3100. * invensense,mpu6050 - Convert to generic device properties. * maxim,ds1803 - Add out_raw_available before supporting more devices. - Convert from of specific to device properties. * samsung,ssp_sensors - Convert from of specific to device properties. * st,stm32-timer trigger - Convert from of specific to device properties. * ti,hdc101x - Add ACPI ID TXNW1010. * ti,tsc2046: - Add read_raw support to enable use of iio_hwmon and similar. Fixes / cleanup. * mailmap - Update for Cai Huoqing * MAINTAINERS - Fix Analog Devices related links. - Add entry for ADRF6780 - Add entry for ADMV1013 - Add entry for AD7293 - Add entry for ADMV8818 - Update files listed for adis-lib * iio core: - Fix wrong comment about current_mode being something a driver should ever access. - Use struct_size() rather than open coding in industrialio-hw-consumer * adi,axl355 - Use units.h definitions instead of local versions. * adi,adis-lib - Simplify *updated_bits() macro - Whitespace cleanup. * afe - Note many of these fixes only apply to particular configurations so the problems have probably not been seen in the wild, but will be visible with new usecases enabled this cycle. - Fix application of consumer scale for IIO_VAL_INT. - Apply a scale of 1 when no scale is provided. - Make best effort to establish a valid offset value for fractional cases. - Use s64 for scale calculations where parameters may be signed. - Tidy up include order. - Improve accuracy for small fractional sales - Reduce risk of integer overflow. * ams,as3935 - Use devm_delayed_work_autocancel() to replace open coded equivalent. * aspeed,adc - Fix wrong use of divider flag. * atmel,sama5d2-adc - Relax atmel,trigger-edge-type to optional. - Drop Ludovic Desroches from listed maintainers of the dt-binding inline with previous MAINTAINERS entry update. * fsl,mma8452 - Fix probing when i2c_device_id used. - dev_get_drvdata() on the iio_dev->dev, no longer returns iio_dev. Use dev_to_iio_dev() instead. Note the original path in here worked more by luck than design. * invensense,mpu6050 - Drop ACPI_PTR() protection to avoid an unused warning. - Use fact ACPI_COMPANION() returns null when ACPI_HANDLE() does to simplify handling. * motorola,cpcap-adc - Drop unused assignment. * qcom,spmi-adc - Fix wrong example of 'reg' in binding document. * renesas,rzg2l-adc - Trivial typo fix. * semtech,sx9360 - Fix wrong register handling for event generation. * st_sensors - Allow manual disabling of I2C or SPI module if not needed for a particular board. Default is still to enable the bus specific module if appropriate bus is supported. * st,lsm6dsx - dev_get_drvdata() on the iio_dev->dev, no longer returns iio_dev. Use dev_to_iio_dev() instead. * ti,palmas-gpadc - Split the interrupt fields in the dt-binding example * ti,tsc2046 - Rework state machine to improve readability after recent debugging of an issue fixed elsewhere. - Add a sanity check to avoid very large memory allocations if a crazy delay is specified. * ti,twl6030 - Add error handling if devm_request_threaded_irq() fails. * xilinx,ams - Use devm_delayed_work_autocancel() instead of open coding equivalent. - Fix missing required clock entry in dt-binding. - Fix miss counting of channels resulting in ps channels not being enabled. - Fix incorrect values written to sequencer registers. - Fix sequence for single channel reading. * tag 'iio-for-5.18a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (245 commits) iio: adc: xilinx-ams: Fix single channel switching sequence iio: adc: xilinx-ams: Fixed wrong sequencer register settings iio: adc: xilinx-ams: Fixed missing PS channels dt-bindings: iio: adc: zynqmp_ams: Add clock entry iio: accel: mma8452: use the correct logic to get mma8452_data iio: adc: aspeed: Add divider flag to fix incorrect voltage reading. iio: imu: st_lsm6dsx: use dev_to_iio_dev() to get iio_dev struct dt-bindings: iio: Add ltc2688 documentation iio: ABI: add ABI file for the LTC2688 DAC iio: dac: add support for ltc2688 dt-bindings: iio: afe: add bindings for temperature transducers dt-bindings: iio: afe: add bindings for temperature-sense-rtd iio: afe: rescale: add temperature transducers iio: afe: rescale: add RTD temperature sensor support iio: test: add basic tests for the iio-rescale driver iio: afe: rescale: reduce risk of integer overflow iio: afe: rescale: fix accuracy for small fractional scales iio: afe: rescale: add offset support iio: afe: rescale: add INT_PLUS_{MICRO,NANO} support iio: afe: rescale: expose scale processing function ...
