Merge tag 'iio-for-7.0a' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-nextJonathan writes:IIO: New device support, features and cleanup for the 6.20/7.0 cycle.Slightly messier than normal unfortunately due to some conflictsand build config bugs related to I3C drivers.One last minute Kconfig fix right at the top after a linux-next report.I've simplified the Kconfig and made it match other instances in the kernelso that should be safe enough despite short soak time in front of build bots.Merge of an immutable branch from I3C to get some stubs that were missingand caused build issues with dual I2C / I3C drivers. 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 up patch replaced use of some deprecated I3C interfaces prior to the I3C immutable branch merge as that includes dropping them.adi,ad4134- New driver for the AD4134 24bit 4 channel simultaneous sampling ADC.adi,ad7768-1,- Add support for the ADAQ767-1, ADAQ7768-1 and ADAQ7769-1 ADCs after some rework to enable the driver to support multiple device types.adi,ad9467- Add support for the similar ad9211 ADC to this existing driver.- Make the selection of 2s comp mode explicit for normal operation and switch to offset binary when entering calibration mode.honeywell,abp2- New driver to support this huge family (100+) of board mount pressure and temperature sensors.maxim,max22007- New drier for this 4 channel DAC.memsic,mmc5633- New driver for this I2C/I3C magnetometer. 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.

Definingthis interrupt in devicetree is optional, therefore we only create anIIO trigger if one is found.Handling this interrupt requires some considerations. When enabling thetrigger the CS line is tied low (active), thus we need to holdspi_bus_lock() too, to avoid state corruption. This is done inside theset_trigger_state() callback, to let users use other triggers withoutwasting a bus lock.Reviewed-by: Andy Shevchenko Signed-off-by: Kurt Borja Reviewed-by: David Lechner Signed-off-by: Jonathan Cameron List of files: /linux/drivers/iio/adc/Kconfig

4434072a893e4864519c167947083ff3e4cc2d95 - iio: adc: Add the NXP SAR ADC support for the s32g2/3 platforms

Mon, 08 Dec 2025 03:08:19 +0100

iio: adc: Add the NXP SAR ADC support for the s32g2/3 platformsThe NXP S32G2 and S32G3 platforms integrate a successive approximationregister (SAR) ADC. Two instances are available, each providing 8multiplexed input channels with 12-bit resolution. The conversion rateis up to 1 Msps depending on the configuration and sampling window.The SAR ADC supports raw, buffer, and trigger modes. It can operatein both single-shot and continuous conversion modes, with optionalhardware triggering through the cross-trigger unit (CTU) or externalevents. An internal prescaler allows adjusting the sampling clock,while per-channel programmable sampling times provide fine-grainedtrade-offs between accuracy and latency. Automatic calibration isperformed at probe time to minimize offset and gain errors.All modes have been validated on the S32G274-RDB2 platform using anexternally generated square wave captured by the ADC. Tests coveredbuffered streaming via IIO, trigger synchronization, and accuracyverification against a precision laboratory signal source.One potential scenario, not detected during testing, is that in somecorner cases the DMA may already have been armed for the nexttransfer, which can lead dmaengine_tx_status() to return an incorrectresidue. The callback_result() operation—intended to supply theresidue directly and eliminate the need to calldmaengine_tx_status()—also does not work. Attempting to usedmaengine_pause() and dmaengine_resume() to prevent the residue frombeing updated does not work either.This potential scenario should apply to any driver using cyclic DMA.However, no current driver actually handles this case, and they all relyon the same acquisition routine (e.g., the STM32 implementation).The NXP SAR acquisition routine has been used in production for severalyears, which is a good indication of its robustness.As the IIO is implementing the cyclic DMA support API, it is not worthto do more spins to the current routine as it will go away when thenew API will be available.The driver is derived from the BSP implementation and has been partlyrewritten to comply with upstream requirements. For this reason, allcontributors to the original code are listed as co-developers.Originally-by: Stefan-Gabriel Mirea Co-developed-by: Alexandru-Catalin Ionita Signed-off-by: Alexandru-Catalin Ionita Co-developed-by: Ciprian Costea Signed-off-by: Ciprian Costea Co-developed-by: Radu Pirea (NXP OSS) Signed-off-by: Radu Pirea (NXP OSS) Signed-off-by: Daniel Lezcano Reviewed-by: Andy Shevchenko Signed-off-by: Jonathan Cameron List of files: /linux/drivers/iio/adc/Kconfig
