Merge tag 'iio-for-7.2a' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio into work-testingIIO: New device support, features and cleanup for the 7.2 cycle.Like many areas of the kernel IIO has seen a lot of new contributorsthough in this case that is not all AI driven, but also reflects and annualsurge of student contributions from usp.br. We also have several newregular reviewers who are helping with the surge (thanks to all ouractive reviewers!)Given there was a lot of cases of similar improvements applied todifferent drivers, I have grouped those into a special section (variousdrivers) to avoid mass duplication.New device support------------------adi,ad4130- Add support for AD4129-4, AD4129-8, AD4130-4, AD4131-4 and AD4131-8 after reworking the driver to be suitable for multiple device support.adi,ad4080- Support the AD4880 and AD4884 dual-channel parts. Interesting parts as have two separate data pipelines (including SPI buses interfaces), but the only current backend IP combines the two so they cannot be treated as independent devices.adi,ad5706r- New driver for this 4 channel current output DAC.adi,ad4691- New driver supporting this family of ADCs. Support for AD4691, AD4692, AD4693 and AD4694 which support either 8 or 16 channels with different max sampling rates. Feature rich driver including SPI offload support.adi,ltc2983- Add support for the ADT7604 in which the same sensor die as the LTC2984 is used for leak detection (liquid coverage of a sense area).allwinner,adc- Support for A523 SoCs. Similar to existing parts but with an additional clock. Includes adding support for non contiguous channel lookup for in kernel use (fwnode_xlate callback).broadcomm,apds9999- New driver for the APDS9999 Ambient Light, RGB and proximity sensor.memsic,mmc5983- New driver for this 3-axis magnetometer.taos,tsl2772- Add support for the AVAGO APDS9900 and APDS9901 Ambient Light and Proximity sensors. which are very similar to existing part with slightly different integration time choices. Includes removal of driver for these parts from drivers/misc.vishay,veml3328- New driver for this RGB+IR light sensor.Features--------IIO Core- Support for IEEE 754 floating point values in buffer scan elements.- Support quaternion axis representation (missing the scaler part)microchip,mcp4821- Add configurable gain controlqcom,pm8xxx-xoadc- Add per channel labels.st,lsm6dsx- Support for rotation sensing on the LSM6DSV and LSM6DSV16X using both floating point and new quaterionaxis rotation modifier.MAINTAINERS update------------------IIO top level entry- Include Documentation/driver-api/iio/adi,*- Top level ADI entry maintainer switch from Lars-Peter Clausen to Nuno Sá reflecting what has been the reality for some time. Thanks to Lars-Peter who was very active for many years, but has moved on to other things. Also add the linux@analog.com email list to ensure we don't get a gap in future.- Maintainer updates to reflect Cosmin Tanislav having moved on - thanks to Marcelo Schmitt for taking these over.sensiron,scd30- Replace maintainer (Tomasz Duszynski) with Maxwell Doose.Cleanups, minor fixes and hardening.------------------------------------Documentation- Add missing powerdown modes to ABI docs.- Use modern helpers for buffer definition in the examples.core- Rework of the handling of timestamps so that the offset is cached at buffer resize time (during enabling) rather than based on assumption that relied in the timestamp being last and the largest element and so always 8 bytes before end of the scan. Underlying problem was triggered by scans with repeated type elements such as quaternions with each element more than 2 bytes - Giving a 16 byte+ aligned channel with result that a following timestamp may be 16 bytes from end of scan, rather than 8. Note that for the bosch,bno55 a compatibility hack means that it will duplicate the timestamp putting a second copy at previously incorrect location.- Tidy up use of kernel types in buffer code to not use int64_t given all calls use s64.various drivers- Drop unused driver_data in device id tables - includes cleanup of various drivers that had only one choice where it can be hard coded elsewhere.- Move to named initializers for many i2c_device_id and platform_device_id tables (I have no idea how we go into habit of using named initializers for only a subset of the table types - e.g. of_device_id).- Make IIO_CHAN_SOFT_TIMESTAMP() macro a compound literal allowing simple use in various drivers that do dynamic channel definitions. Use it in all such cases.- Use dev_err_probe() and local dev variables to tidy up older drivers.- Switch more drivers to devm_mutex_init() to provide minor debug benefits.- Reorder code to put MODULE_DEVICE_TABLE() next to the tables.- Lots of use of cleanup.h magic to improve code flow, often including related refactors such as introducing helpers.- Replacement of usleep_range() with fsleep()- Reduce logging noise where functions either provide their own extensive reports on error, or where a clear error code is returned to userspace.- Minor spelling and style fixes (improving bracket usage, not using __packed etc)hid-sensors-*- Drop helpers for setting channel bit masks in favor of a compound literal at the call site. Also general cleanup of surrounding code.hid-sensors-magn- Use u32 rather than bare unsigned for types.hid-sensors-rotation- Make sue of ext_scan_type handling for static case rather than duplicate chan_info structures.adi,ad3552r- Use field_get() to replace open coded equivalent.adi,ad4170- Switch from switch to table lookup for GPIO modes.adi,ad5686- Apply IWYU principal to included a consistent set of headers.- Deduplicate regmaps for AD5684 and AD5693 as identical.- Switch from an enum value in driver data and array look up to pointers to separate structures, improving readabilty and avoiding issues with 0 value when using helpers to deal with different firmware types.- Add of_match_id table to SPI driver rather than relying on fallback to spi_device_id table.- Introduce some helpers for powerdown mask control.- Add helpers for control sync simplifying a couple of corner cases.- Docs fixes.- Add an ops structure to simplify future addition of operations beyond read and write.adi,ad7191- Switch to best practice of using device_property_present() to detect if an optional property is there rather than error values on querying the property.adi,ad7280a- Use local variables to improve readability of breaking up chan-address.adi,ad7825- Cleanup a type mismatch in clamp() call.adi,ad799x- Include improvements- Local dev variable to shorten code lines.- Cache regulator voltage at probe (these never change in practice)- Convert to devm for all unwind handling.adi,ad9832- Improve include relevance including replacing kernel.h with more specific headers.- Simplify some maths.adi,ad9834- Improve include relevance including replacing kernel.h with more specific headers.adi,adt7316- Add a comment to avoid future 'fixes' for error handling during the odd sequence used to flip from I2C mode to SPI mode.adi,adxl*- Documentation consistency improvements.asahi-kasei,ak8975- Fix missing runtime pm calls for buffered capture.- Fix missing pm_runtime_put_autosuspend() in an error path that would leave the device stuck on.- Close a potential uninitialized kernel stack leak.- Extensive driver modernization including: header relevance, fsleep() various minor bugs, dropping duplicate error messages and avoiding magic lengths for buffers.- Replace opencoded polling with iopoll().- Add error checking to gpio reads.avia,hx711- Move scale computation from global data to per device avoiding problems if multiple devices present.- General binding text cleanup.bosch,bmg160- Add missing mount-matrix entry to binding.bosch,bno55- Terminate error strings with newlines.devantech,srf08- Replace sprintf() with sysfs_emit() and sysfs_emit_at() to make intent clearer.freescale,mma8452- Add missing return value check.- Fix potential probe ordering issue by switching to non devm irq request.linear,ltc2309- Add chip specific read delays.- Improve chip_info structure, adding __counted_by_ptr marking and reorganizing to improve packing.linear,ltc2983- Fix a firmware combination where default n_wires of 2 bypasses exclusion of adi,current-rotate whereas explicitly setting it to 2 does not.- Fix potential race with completion reinit.- Improve error message wording consistency.- Use fwnode_property_present() to detect optional properties rather than fragile return value checking.microchip,mcp3422- Use of GENMASK(), FIELD_GET(), FIELD_PREP() to improve readability and generally modernize driver.microchip,mcp47feb02- Fix binding example to use a possible I2C address.- Fix binding bounds on channel number.- Standardize binding example indentationnxp,saradc- Increase chances of recovering from a failure in the interrupt handler by notifying the trigger that it can reenable even when the read failed.- Use field_get() to replace opencoded equivalent.qualcomm,*- Standardize on Qualcomm company naming in Kconfig.richtek,rtq6056- Add i2c_device_id table for legacy instantiation.samsung,ssp- Replace custom timestamp channel macro with main one.sciosense,ens210- Now scoped_guard() has been reworked, no need for a return that can never be reached.sensiron,scd30- Constify command lookup table.- Sanity check for NULL buffer of non zero size being provided to sc30_i2c_command()sensortek,stk3310- Include more appropriate headers.- Ensure interrupt in appropriate mode after resume.- Structure definition improvements.- Use size_of() to replace opencoded sizes.siliconimage,si1133- Resolve counter related issues on timeout error paths.- Unused macro removal, improved macro definitions,.- Include relevance improvements.st,lsm6dsx- Fix an issue with applying invalid data check to wrong type of sample.taos,tcs3472- Try to powerdown chip on probe failure.- Devm usage and dropping of remove() callback.- Various other minor cleanup.taos,tsl2591- Dead code removal.- Simplify tsl2591_persist functions using a look up table.ti,ads1298- Fix wrong comment on timeout (and minor code improvement)- Drop unnecessary CONFIG2 write during init.ti,ads7950- Check ret rather that ret < 0 for spi_setup() call.- Use fully devm managed resources including moving to devm_regulator_get_enable_read_voltage() at probe time rather than querying evey time.- Using spi_optimize_message() to reduce CPU usage.ti,ads8688- User read_avail() callback rather than open coding handling of available attributes.ti,opt3001- Header relevance improvements- Use GENMASK for field definitions to improve readability.vishay,vcnl4000- Switch from enum in device_data to individual names structures impmroving code readabililty.- Move to devm handling for remainder of probe.vishay,veml6030- Drop pointless read of current Iteration Time index as it is not used.xilinx,ams- Fix potential out of bound channel lookup.- Replace some large switch statements with table lookups.yamaha,yas530- Put label in chip info structure to avoid look up in i2c_device_id table.Drop----iio-trig-interrupt.- Not used for some time and no support for modern firmware bindings or in kernel users.

f68afce8e8a74f52a879f56f607dfedf552b5ab5 - iio: Initialize i2c_device_id arrays using member names

Tue, 19 May 2026 10:13:09 +0200

iio: Initialize i2c_device_id arrays using member namesWhile being less compact, using named initializers allows to more easilysee which members of the structs are assigned which value without havingto lookup the declaration of the struct. And it's also more robustagainst changes to the struct definition.The mentioned robustness is relevant for a planned change to structi2c_device_id that replaces .driver_data by an anonymous union.This patch doesn't modify the compiled arrays, only their representationin source form benefits. The former was confirmed with x86 and arm64builds.Signed-off-by: Uwe Kleine-König (The Capable Hub) Reviewed-by: Siratul Islam Reviewed-by: Matti Vaittinen Signed-off-by: Jonathan Cameron List of files: /linux/drivers/iio/light/opt4060.c

This also brought in adrop of some deprecated interfaces so there is also one patch to update anew driver to not use those.We are having another go at using cleanup.h magic with the IIO mode claimfunctions after backing out last try at this. This time we have wrappersaround the new ACQUIRE() and ACQUIRE_ERR() macros.Having been burnt once, we will be taking it a bit more slowly this timewrt to wide adoption of these! Thanks in particular to Kurt for takingon this core IIO work.New Device Support==================adi,ad18113- New driver to support the AD18113 amplifier - an interesting device due to the external bypass paths where we need to describe what gain those paths have in DT. Longer term it will be interesting to see if this simplistic description is enough for real deployments.adi,ad4062- New driver for the AD4060 and AD4052 SAR ADCs including trigger, event and GPIO controller support.

Follow on patches fixed up issues related to single driver supporting both bus types.microchip,mcp747feb02- New driver for the Microchip MCP47F(E/V)B(0/1/2)1, MCP47F(E/V)B(0/1/2)2, MCP47F(E/V)B(0/1/2)4 and MCP47F(E/V)B(0/1/2)8 buffered voltage output DACs.nxp,sar-adc- New driver support ADCs found on s32g2 and s32g3 platforms.ti,ads1018- New drier for the ADS1018 and ADS1118 SPI ADCs.ti,ads131m02- New driver supporting ADS131M(02/03/04/06/08)24-bit simultaneous sampling ADCs.Features========iio-core- New IIO_DEV_ACQUIRE_DIRECT_MODE() / IIO_DEV_ACQUIRE_FAILED() + equivalents for the much rarer case where the mode needs pinning whether or not it is in direct mode. These use the ACQUIRE() / ACQUIRE_ERR() infrastructure underneath to provide both simple checks on whether we got the requested mode and to provide scope based release. Applied in a few initial drivers.adi,ad9467- Support calibbias controladi,adf4377- Add support to act as a clock provider.adi,adxl380- Support low power 1KHz sampling frequency mode. Required rework of how events and filters were configured, plus applying of constraints when in this mode.rf-digital,rfd77402- Add interrupt support as alternative to polling for completion.st,lsm6dsx- Tap event detection (after considerable driver rework)Cleanup and Minor Fixes=======================More minor cleanup such as typos, white space etc not called out exceptwhere they were applied to a lot of drivers.Various drivers.- Use of dev_err_probe() to cleanup error handling.- Introduce local struct device and struct device_node variables to reduce duplication of getting them from containing structs.- Ensure uses of iio_trigger_generic_data_rdy_poll() set IRQF_NO_THREAD as that function calls non threaded child interrupt handlers.- Replace IRQF_ONESHOT in not thread interrupt handlers with IRQF_NO_THREAD to ensure they run as intended. Drop one unnecessary case.iio-sw-device/trigger.- Constify configs_group_operations structures.iio-buffer-dma / buffer-dma-engine- Use lockdep_assert_held() to replace WARN_ON() to check lock is correctly held.- Make use of cleanup.h magic to simplify various code paths.- Make iio_dma_buffer_init() return void rather than always success.adi,ad7766- Replace custom interrupt handler with iio_trigger_generic_data_rdy_poll()adi,ad9832- Drop legacy platform_data support.adi,ade9000- Add a maintainer entry.adi,adt7316- Move to EXPORT_GPL_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() so the compiler can cleanly drop unused pm structures and callbacks.adi,adxl345- Relax build constraint vs the driver that is in input so both may be built as modules and selection made at runtime.adi,adxl380- Make sure we don't read tail entries in the hardware fifo if a partial new scan has been written.- Move to a single larger regmap_noinc_read() to read the hardware fifo.aspeed,ast2600- Add missing interrupts property to DT binding.bosch,bmi270_i2c- Add missing MODULE_DEVICE_TABLE() macros so auto probing of modules can work.bosch,smi330- Drop duplicate assignment of IIO_TYPE in smi330_read_avail()- Use new common field_get() and field_prep() helpers to replace local version.honeywell,mprls0025pa Fixes delayed to merge window as late in cycle and we didn't want to delay the rest of the series.- Allow Kconfig selection of specific bus sub-drivers rather than tying that to the buses themselves being supported.- Zero spi_transfer structure to avoid chance of unintentionally set fields effecting transfer.- Fix a potential timing violation wrt to the chip select to first clock edge timing.- As recent driver, take risk inherent in dropping interrupt direction from driver as that should be set by firmware.- Fix wrong reported number of data bits for channel.- Fix a pressure channel calculation bug.- Rework to allow embedding the tx buffer in the iio_priv() structure rather than requiring separate allocation.- Move the buffer clearing to the shared core bringing it into affect for SPI as well as I2C.- Stricter checks for status byte.- Greatly simplify the measurement sequence.- Add a copyright entry to reflect Petre's continued work on this driver.intersil,isl29018- Switch from spritnf to sysfs_emit_at() to make it clear overflow can't occur.invensense,icm42600- Allow sysfs access to temperature when buffered capture in use as it does not impact other sensor data paths.invensense,itg3200- Check unused return value in read_raw() callback.men,z188- Drop now duplicated module alias.rf-digital,rfd77402- Add DT binding doc and explicit of_device_id table.- Poll for timeout with times as on datasheet, then replace opencoded version with read_poll_timeout().sensiron,scd4x- Add missing timestamp channel. The code to push it to the buffer was there but there was no way to turn it on.vti,sca3000- Fix resource leak if iio_device_register() fails.* tag 'iio-for-7.0a' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (144 commits) iio: magn: mmc5633: Fix Kconfig for combination of I3C as module and driver builtin iio: sca3000: Fix a resource leak in sca3000_probe() iio: proximity: rfd77402: Add interrupt handling support iio: proximity: rfd77402: Document device private data structure iio: proximity: rfd77402: Use devm-managed mutex initialization iio: proximity: rfd77402: Use kernel helper for result polling iio: proximity: rfd77402: Align polling timeout with datasheet iio: cros_ec: Allow enabling/disabling calibration mode iio: frequency: ad9523: correct kernel-doc bad line warning iio: buffer: buffer_impl.h: fix kernel-doc warnings iio: gyro: itg3200: Fix unchecked return value in read_raw MAINTAINERS: add entry for ADE9000 driver iio: accel: sca3000: remove unused last_timestamp field iio: accel: adxl372: remove unused int2_bitmask field iio: adc: ad7766: Use iio_trigger_generic_data_rdy_poll() iio: magnetometer: Remove IRQF_ONESHOT iio: Replace IRQF_ONESHOT with IRQF_NO_THREAD iio: Use IRQF_NO_THREAD iio: dac: Add MAX22007 DAC driver support dt-bindings: iio: dac: Add max22007 ...

Tue, 20 Jan 2026 07:20:43 +0100

iio: core: Match iio_device_claim_*() semantics and implementationImplement iio_device_claim_buffer_mode() fully inline with the use of__iio_dev_mode_lock(), which takes care of sparse annotations.To completely match iio_device_claim_direct() semantics, we need toalso change iio_device_claim_buffer_mode() return semantics to usualtrue/false conditional lock semantics.Additionally, to avoid silently breaking out-of-tree drivers, renameiio_device_claim_buffer_mode() to iio_device_claim_try_buffer_mode().Reviewed-by: David Lechner Reviewed-by: Nuno Sá Signed-off-by: Kurt Borja Signed-off-by: Jonathan Cameron List of files: /linux/drivers/iio/light/opt4060.c
