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. Various other minor tweaks and fixes not called out. * ---------------------------------------------------------------- Alisa-Dariana Roman (3): dt-bindings: iio: adc: add AD7191 iio: adc: ad7191: add
