2025-07-14iio: Add driver for Nicera D3-323-AA PIR sensorWaqar Hameed
Nicera D3-323-AA is a PIR sensor for human detection. It has support for raw data measurements and detection notification. The communication protocol is custom made and therefore needs to be GPIO bit banged. The device has two main settings that can be configured: a threshold value for detection and a band-pass filter. The configurable parameters for the band-pass filter are the high-pass and low-pass cutoff frequencies and its peak gain. Map these settings to the corresponding parameters in the `iio` framework. Raw data measurements can be obtained from the device. However, since we rely on bit banging, it will be rather cumbersome with buffer support. The main reason being that the data protocol has strict timing requirements (it's serial like UART), and it's mainly used during debugging since in real-world applications only the event notification is of importance. Therefore, only add support for events (for now).

2025-06-09iio: Remove single use of macro definition for IRQ nameWaqar Hameed
There is really no reason for having the IRQ name as a macro definition if it is only used once (often in functions requesting the IRQ). It is also more readable this way.

2025-05-21iio: proximity: irsd200: Use a struct for scan and iio_push_to_buffers_with_ts()Jonathan Cameron
The driver previously used an array of two s64, then type cast the pointer to write an s16 to the start. The code is made more readable using a structure. At the same time switch to the new iio_push_to_buffers_with_ts() helper to enable runtime checking of the size of the source buffer. Note that this approach uses a structure with holes, so use memset() to ensure those do not contain old kernel data as this data is passed to userspace.

2025-04-22iio: normalize array sentinel styleDavid Lechner
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.

The usual mixture of new drivers, support in existing drivers for new devices, a range of features and general subsystem cleanup. Two merges of immutable branches in here: * SPI offload support. Culmination of a long effort to bring the ability to offload triggered sequences of SPI operations to specific hardware, allow high datarate acquisition over an SPI bus (if you have the right hardware / FPGA firmware) * GPIO set-array-helper - enables code simplification. New device support ================== adi,ad3552r-hs: - Add support for AD3541r and AD3542r via newly supported FPGA HDL. adi,ad4030 - New driver supporting the AD4030, AD4630 AD4630-16, AD4640-24, AD4632-16, AD4632-24 1 and 2 channel high precision SPI ADCs. adi,ad4851 - New driver and backend support for the AD4851, AD4852, AD4853, AD4854, AD4855, AD4846, AD4857, AD4858 and AD4858I high speed multichannel simultaneous sampling ADCs. adi,ad7191 - New driver for this 24-bit ADC for precision bridge applications, adi,ad7380 - Add support for the adaq4381-4 which is a 14-bit version of the already supported adaq4380-1 adi,adis16550 - New driver using the ADIS library (which needed extensions) for this IMU. brcm,apds9160 - New driver for this proximity and ambient light sensor. dynaimage,al3000a - New driver for this illuminance sensor. mcube,mc3230 - Add support for the mc3510c accelerometer with a different scale to existing supported parts (some rework preceded this) nxp,imx93 - Add compatibles for imx94 and imx95 which are fully compatible with imx93. rockchip,saradc - Add support for the RK3528 ADC - Add support for the RK3562 ADC silab,si7210 - New driver to support this I2C Hall effect magnetic position sensor. ti,ads7138 - New driver supporting the ADS7128 and AD7138 I2C ADCs. Staging driver drop =================== adi,adis16240 - Drop this impact sensor. Interesting part but complex hence never left staging due to ABI challenges. No longer readily available so drop driver. New features ============ Documentation - A really nice overview document introduce ADC terminology and how it maps to IIO. core - New description for FAULT events, used in the ad7173. - filter_type ABI used in ad4130. buffer-dmaengine - Split DMA channel request from buffer allocation (for SPI offload) - Add a new _with_handle setup variant. (for SPI offload) adi,adf4371 - Add control of reference clock type and support for frequency doubling where appropriate. adi,ad4695 - Support SPI offload. - Support oversampling control. adi,ad5791 - Support SPI offload. adi,ad7124 - Add channel calibration support. adi,ad7380: - Alert support (threshold interrupts) - SPI offload support. adi,ad7606 - Support writing registers when using backend enabling software control of modes. adi,ad7944 - Support SPI offload. adi,ad9832 - Use devm_regulator_get_enable() to simplify code. adi,ad9834 - Use devm_regulator_get_enable() to simplify code. adi,adxl345 - Improve IRQ handling code. - Add debug access to registers. bosch,bmi270 - Add temperature channel support. - Add data ready trigger. google,cross_ec - Add trace events. mcube,mc3230 - Add mount matrix support - Add an OF match table. Cleanup and minor bug fixes =========================== Tree wide: - Stop using iio_device_claim_direct_scoped() and introduce sparse friendly iio_device_claim/release_direct() The conditional scoped cleanup has proved hard to deal with, requiring workarounds for various compiler issues and in is rather non-intuitive so abandon that experiment. One of the attractions of that approach was that it made it much harder to have unbalanced claim/release bugs so instead introduce a conditional-lock style boolean returning new pair of functions. These are inline in the header and have __acquire and __release calls allowing sparse to detect lack of balance. There are occasional false positives but so far those have reflected complex code paths that benefited from cleanup anyway. The first set of driver conversions are in this pull request, more to follow next cycle. Various related cleanup in drivers. Removal of the _scoped code is completed and the definition removed. - Use of str_enable_disable() and similar helpers. - Don't set regmap cache to REGCACHE_NONE as that's the default anyway. - Change some caches from RBTREE to MAPLE reflecting best practice. - Use the new gpiod_multi_set_value_cansleep() - Make sure to grab direct mode for some calibrations paths. - Avoid using memcmp on structures when checking for matching channel configs. Instead just match field by field. dt-bindings: - Fix up indentation inconsistencies. gts-helper: - Simplify building of available scale table. adi,ad-sigma-delta - Make sure to disable channel after calibration done. - Add error handling in configuring channel during calibration. adi,ad2s1201 - use a bitmap_write() rather than directly accessing underlying storage. adi,ad3552r-hs - Fix a wrong error message. - Make sure to use instruction mode for configuration. adi,ad4695 - Add a conversion to ensure exit from conversion mode. - Use custom regmap to handle required sclk rate change. - Fix an out of bounds array access - Simplify oversampling ratio handling. adi,ad4851 - Fix a sign bug. adi,ad5791 - Fix wrong exported number of storage bits. adi,ad7124 - Disable all channels at probe to avoid strange initial configurations. adi,ad7173 - Rework to allow static const struct ad_sigma_delta without need to make a copy. adi,ad7623 - Drop a BSD license tag that the authors consider unnecessary. adi,ad7768-1 - Fix channels sign description exposed to user space. - Set MOSI idle state to avoid accidental device reset. - Avoid some overkill locking. adi,axi-dac - Check if device interface is busy when enabling data stream. - Add control of bus mode. bosch,bmi270 - Move a struct definition to a c file as only used there. vishay,veml6030 - Enable regmap cache to reduce bus traffic. - Fix ABI bug around scale reporting. vishay,vem6075 - Check array bounds to harden against broken hardware.

2024-10-10iio: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/iio/ to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in several files.

2024-09-30iio: proximity: vl53l0x-i2c: Added continuous mode supportAbhash Jha
The continuous mode of the sensor is enabled in the buffer_postenable. Replaced the original irq handler with a threaded irq handler to perform i2c reads during continuous mode. The continuous mode is disabled by disabling the buffer. Added a trigger for this device to be used for continuous mode.

2024-05-27iio: Drop explicit initialization of struct i2c_device_id::driver_data to 0Uwe Kleine-König
These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove commas after the sentinel entries.
