2025-09-10iio: imu: inv_icm42600: Use devm_regulator_get_enable() for vdd regulatorSean Nyekjaer2-24/+6
The vdd regulator is not used for runtime power management, so it does not need explicit enable/disable handling. Use devm_regulator_get_enable() to let the regulator be managed automatically by devm. This simplifies the code by removing the manual enable and cleanup logic.

Do as in suspend, skip resume configuration steps if the device is already pm_runtime suspended. This avoids reconfiguring a device that is already in the correct low-power state and ensures that pm_runtime handles the power state transitions properly.

Remove unnecessary calls to pm_runtime_disable(), pm_runtime_set_active(), and pm_runtime_enable() from the resume path. These operations are not required here and can interfere with proper pm_runtime state handling, especially when resuming from a pm_runtime suspended state.

2025-09-10iio: imu: inv_icm42600: Simplify pm_runtime setupSean Nyekjaer1-17/+7
Rework the power management in inv_icm42600_core_probe() to use devm_pm_runtime_set_active_enabled(), which simplifies the runtime PM setup by handling activation and enabling in one step. Remove the separate inv_icm42600_disable_pm callback, as it's no longer needed with the devm-managed approach. Using devm_pm_runtime_enable() also fixes the missing disable of autosuspend. Update inv_icm42600_disable_vddio_reg() to only disable the regulator if the device is not suspended i.e. powered-down, preventing unbalanced disables. Also remove redundant error msg on regulator_disable(), the regulator framework already emits an error message when regulator_disable() fails. This simplifies the PM setup and avoids manipulating the usage counter unnecessarily.

2025-08-25iio: imu: bmi270: Match PNP ID found on newer GPD firmwareCryolitia PukNgae1-0/+2
GPD devices originally used BMI160 sensors with the "BMI0160" PNP ID. When they switched to BMI260 sensors in newer hardware, they reused the existing Windows driver which accepts both "BMI0160" and "BMI0260" IDs. Consequently, they kept "BMI0160" in DSDT tables for new BMI260 devices, causing driver mismatches in Linux. 1. GPD updated BIOS v0.40+[1] for newer devices to report "BMI0260" for BMI260 sensors to avoid loading the bmi160 driver on Linux. While this isn't Bosch's VID; 2. Bosch's official Windows driver uses "BMI0260" as a compatible ID 3. We're seeing real devices shipping with "BMI0260" in DSDT The DSDT excerpt of GPD G1619-04 with BIOS v0.40: Scope (_SB.I2CC) { Device (BMA2) { Name (_ADR, Zero) // _ADR: Address Name (_HID, "BMI0260") // _HID: Hardware ID Name (_CID, "BMI0260") // _CID: Compatible ID Name (_DDN, "Accelerometer") // _DDN: DOS Device Name Name (_UID, One) // _UID: Unique ID Method (_CRS, 0, NotSerialized) // _CRS: Current Resource Settings { Name (RBUF, ResourceTemplate () { I2cSerialBusV2 (0x0069, ControllerInitiated, 0x00061A80, AddressingMode7Bit, "\\_SB.I2CC", 0x00, ResourceConsumer, , Exclusive, ) }) Return (RBUF) /* \_SB_.I2CC.BMA2._CRS.RBUF */ } # omit some noise } } Link: http://download.softwincn.com/WIN%20Max%202024/Max2-7840-BIOS-V0.41.zip #1 Signed-off-by: Cryolitia PukNgae <cryolitia@uniontech.com> Reviewed-by: Andy Shevchenko <andy@kernel.org> Acked-by: Alex Lanzano <lanzano.alex@gmail.com> Link: https://patch.msgid.link/20250821-bmi270-gpd-acpi-v4-1-5279b471d749@uniontech.com Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

2025-07-14iio: imu: bno055: fix OOB access of hw_xlate arrayDavid Lechner1-3/+8
Fix a potential out-of-bounds array access of the hw_xlate array in bno055.c. In bno055_get_regmask(), hw_xlate was iterated over the length of the vals array instead of the length of the hw_xlate array. In the case of bno055_gyr_scale, the vals array is larger than the hw_xlate array, so this could result in an out-of-bounds access. In practice, this shouldn't happen though because a match should always be found which breaks out of the for loop before it iterates beyond the end of the hw_xlate array. By adding a new hw_xlate_len field to the bno055_sysfs_attr, we can be sure we are iterating over the correct length.

Move all DMA aligned buffers together at the end of the structure. 1. Timestamp anynomous structure is not used with DMA so it doesn't belong after __aligned(IIO_DMA_MINALIGN). 2. struct inv_icm42600_fifo contains it's own __aligned(IIO_DMA_MINALIGN) within it at the end so it should not be after __aligned(IIO_DMA_MINALIGN) in the outer struct either. 3.

Refactors inv_mpu_aux_read() and inv_mpu_aux_write() to extract the common I2C transfer sequence into inv_mpu_i2c_master_xfer(), which now handles starting and stopping the I2C master, waiting for completion, disabling SLV0, and checking for NACK errors. This refactoring removes code duplication and improves maintainability. No functional changes are intended.

ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: IIO: New device support, features and cleanup for 6.16 - take 2 Note - last minute rebase was to drop a typo patch that I'd accidentally picked up (in the microblaze arch Kconfig) Take 2 is due to that rebase messing up some fixes tags that were referring to patches after that point. There is a known merge conflict due to changes in neighbouring lines. Stephen's resolution in linux-next is: https://lore.kernel.org/linux-next/20250506155728.65605bae@canb.auug.org.au/ Added 3 named IIO reviewers to MAINTAINERS. This is a reflection of those who have been doing much of this work for some time. Lars-Peter is removed from the entry having moved on to other topics. Thanks Nuno, David and Andy for stepping up and Lars-Peter for all your hard work in the past! Includes the usual mix of new device support, features and general cleanup. This time we also have some tree wide changes. - Rip out the iio_device_claim_direct_scoped() as it proved hard to work with. This series includes quite a few related cleanups such as use of guard or factoring code out to allow direct returns. - Switch from iio_device_claim/release_direct_mode() to new iio_device_claim/release_direct() which is structured so that sparse can warn on failed releases. There were a few false positives but those were mostly in code that benefited from being cleaned up as part of this process. - Introduce iio_push_to_buffers_with_ts() to replace the _timestamp() version over time. This version takes the size of the supplied buffer which the core checks is at least as big as expected by calculation from channel descriptions of those channels enabled. Use this in an initial set of drivers. - Add macros for IIO_DECLARE_BUFFER_WITH_TS() and IIO_DECLARE_DMA_BUFFER_WITH_TS() to avoid lots of fiddly code to ensure correctly aligned buffers for timestamps being added onto the end of channel data. New device support ------------------ adi,ad3530r - New driver for AD3530, AD3530R, AD3531 and AD3531R DACs with programmable gain controls. R variants have internal references. adi,ad7476 - Add support (dt compatible only) for the Rohm BU79100G ADC which is fully compatible with the ti,ads7866. adi,ad7606 - Support ad7606c-16 and ad7606c-18 devices. Includes switch to dynamic channel information allocation. adi,ad7380 - Add support for the AD7389-4 dfrobot,sen0322 - New driver for this oxygen sensor. mediatek,mt2701-auxadc - Add binding for MT6893 which is fully compatible with already supported MT8173. meson-saradc - Support the GXLX SoCs. Mostly this is a workaround for some unrelated clock control bits found in the ADC register map. nuvoton,nct7201 - New driver for NCT7201 and NCT7202 I2C ADCs. rohm,bd79124 - New driver for this 12-bit, 8-channel SAR ADC. - Switch to new set_rv etc gpio callbacks that were added in 6.15. rohm,bd79703 - Add support for BD79700, BD79701 and BD79702 DACs that have subsets of functionality of the already supported bd79703. Included making this driver suitable for support device variants. st,stm32-lptimer - Add support for stm32pm25 to this trigger. Features -------- Beyond IIO - Property iterator for named children. core - Enable writes for 64 bit integers used for standard IIO ABI elements. Previously these could be read only. - Helper library that should avoid code duplication for simpler ADC bindings that have a child node per channel. - Enforce that IIO_DMA_MINALIGN is always at least 8 (almost always true and simplifies code on all significant architectures) core/backend - Add support to control source of data - useful when the HDL includes things like generated ramps for testing purposes. Enable this for adi-axi-dac adi,ad3552-hs - Add debugfs related callbacks to allow debug access to register contents. adi,ad4000 - Support SPI offload with appropriate FPGA firmware along with improving documentation. adi,ad7293 - Add support for external reference voltage. adi,ad7606 - Support SPI offload. adi,ad7768-1 - Support reset GPIO. adi,admv8818 - Support filter frequencies beyond 2^32. adi,adxl345 - Add single and double tap events. hid-sensor-prox - Support 16-bit report sizes as seen on some Intel platforms. invensense,icm42600 - Enable use of named interrupts to avoid problems with some wiring choices. Get the interrupt by name, but fallback to previous assumption on the first being INT1 if no names are supplied. microchip,mcp3911 - Add reset gpio support. rohm,bh7150 - Add reset gpio support. st,stm32 - Add support to control oversampling. ti,adc128s052 - Add support for ROHM BD79104 which is early compatible with the TI parts already supported by this driver. Includes some general driver cleanup and a separate dt binding. - Simplify reference voltage handling by assuming it is fixed after enabling the supply. winsen,mhz19b - New driver for this C02 sensor. Cleanup and minor fixes ----------------------- dt-bindings - Correct indentation and style for DTS examples. - Use unevalutateProperties for SPI devices instead of additionalProperties to allow generic SPI properties from spi-peripheral-props.yaml ABI Docs - Add missing docs for sampling_frequency when it applies only to events. Treewide - Various minor tweaks, comment fixes and similar. - Sort TI ADCs in Kconfig that had gotten out of order. - Switch various drives that provide GPIO chip functionality to the new callbacks with return values. - Standardize on { } formatting for all array sentinels. - Make use of aligned_s64 in a few places to replace either wrong types or manually defined equivalents. - Drop places where spi bits_per_word is set to 8 because that is the default anyway. adi,ad_sigma_delta library - Avoid a potential use of uninitialized data if reg_size has a value that is not supported (no drivers hit this but it is reasonable hardening) adi,ad4030 - Add error checking for scan types and no longer store it in state. - Rework code to reduce duplication. - Move setting the mode from buffer preenable() to update_scan_mode(), better matching expected semantics of the two different callbacks. - Improve data marshalling comments. adi,ad4695 - Use u16 for buffer elements as oversampling is not yet supported except with SPI offload (which doesn't use this path). adi,ad5592r - Clean up destruction of mutexes. - Use lock guards to simplify code (later patch fixes a missed unlock) adi,ad5933 - Correct some incorrect settling times. adi,ad7091 - Deduplicate handling of writable vs volatile registers as they are the inverse of each other for this device. adi,ad7124 - Fix 3db Filter frequency. - Remove ability to directly write the filter frequency (which was broken) - Register naming improvements. adi,ad7606 - Add a missing return value check. - Fill in max sampling rates for all chips. - Use devm_mutex_init() - Fix up some kernel-doc formatting issues. - Remove some camel case that snuck in. - Drop setting address field in channels as easily established from other fields. - Drop unnecessary parameter to ad76060_scale_setup_cb_t. adi,ad7768-1 - Convert to regmap. - Factor out buffer allocation. - Tidy up headers. adi,ad7944 - Stop setting bits_per_word in SPI xfers with no data. adi,ad9832 - Add of_device_id table rather than just relying on fallbacks. - Use FIELD_PREP() to set values of fields. adi,admv1013 - Cleanup a pointless ternary. adi,admv8818 - Fix up LPF Band 5 frequency which was slightly wrong. - Fix an integer overflow. - Fix range calculation adi,adt7316 - Replace irqd_get_trigger_type(irq_get_irq_data()) with simpler irq_get_trigger_type() adi,adxl345 - Use regmap cache instead of various state variables that were there to reduce bus accesses. - Make regmap return value checking consistent across all call sites. adi,axi-dac - Add a check on number of channels (0 to 15 valid) allwinner,sun20i - Use new adc-helpers to replace local parsing code for channel nodes. bosch,bmp290 - Move to local variables for sensor data marshalling removing the need for a messy definition that has to work for all supported parts. Follow up fix adds a missing initialization. dynaimage,al3010 and dynaimage,al3320a - Various minor cleanup to bring these drivers inline with reviewed feedback given on a new driver. - Fix an error path in which power down is not called when it should be. - Switch to regmap. google,cros_ec - Fix up a flexible array in middle of structure warning. - Flush fifo when changing the timeout to avoid potential long wait for samples. hid-sensor-rotation - Remove an __aligned(16) marking that doesn't seem to be justified. kionix,kxcjk-1013 - Deduplicate code for setting up interrupts. microchip,mcp3911 - Fix handling of conversion results register which differs across supported devices. idt,zopt2201 - Avoid duplicating register lists as all volatile registers are the inverse of writeable registers on this device. renesas,rzg2l - Use new adc-helpers to replace local parsing code for channel nodes. ti,ads1298 - Fix a missing Kconfig dependency. * tag 'iio-for-6.16a-take2' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (260 commits) dt-bindings: iio: adc: Add ROHM BD79100G iio: adc: add support for Nuvoton NCT7201 dt-bindings: iio: adc: add NCT7201 ADCs iio: chemical: Add driver for SEN0322 dt-bindings: trivial-devices: Document SEN0322 iio: adc: ad7768-1: reorganize driver headers iio: bmp280: zero-init buffer iio: ssp_sensors: optimalize -> optimize HID: sensor-hub: Fix typo and improve documentation iio: admv1013: replace redundant ternary operator with just len iio: chemical: mhz19b: Fix error code in probe() iio: adc: at91-sama5d2: use IIO_DECLARE_BUFFER_WITH_TS iio: accel: sca3300: use IIO_DECLARE_BUFFER_WITH_TS iio: adc: ad7380: use IIO_DECLARE_DMA_BUFFER_WITH_TS iio: adc: ad4695: rename AD4695_MAX_VIN_CHANNELS iio: adc: ad4695: use IIO_DECLARE_DMA_BUFFER_WITH_TS iio: introduce IIO_DECLARE_BUFFER_WITH_TS macros iio: make IIO_DMA_MINALIGN minimum of 8 bytes iio: pressure: zpa2326_spi: remove bits_per_word = 8 iio: pressure: ms5611_spi: remove bits_per_word = 8 ...

2025-04-22iio: normalize array sentinel styleDavid Lechner19-32/+32
Use `\t(\{ ?\},|\{\}|\{\s*/\*.*\*/\s*\},?)$` regex to find and replace the array sentinel in all IIO drivers to the same style. For some time, we've been trying to consistently use `{ }` (no trailing comma, no comment, one space between braces) for array sentinels in the IIO subsystem. Still nearly 50% of existing code uses a different style. To save reviewers from having to request this trivial change as frequently, let's normalize the style in all existing IIO drivers. At least when code is copy/pasted to new drivers, the style will be consistent.
