Merge tag 'iio-for-6.11a' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-testing Jonathan writes: IIO: 1st set of new device support, cleanups etc for 6.11 Lots of new device support and 3 entirely new drivers. Early pull request this cycle to allow for clean picking up of fixes that are dependencies for some queued patch sets. Device support ============== adi,ad3552r - Add AD3541R and AD3551R - single output variants of already supported DACs. adi,ad7192 - Add support for ad7194 24-bit ADC with integrated PGA. adi,ad7380 - New ADC driver built up in a number of steps. Supports - 2 channel differential ADCs: AD7380, AD7381 - 4 channel differential ADCs: AD7380-4, AD7381-4 - 2 channel pseudo-differential ADCs: AD7383, AD7384 - 4 channel pseudo-differential ADCs: AD7383-4, AD7384-4 adi,adis16475 - Support ADS16501 variant - ID and some different scale factors from parts already supported. - Driver refactoring then enables support for 6 more IMUs: - ADIS16575-[2,3] - ADIS16576-[2,3] - ADIS16577-[2,3] adi,adsi16480 - Driver refactoring and feature additions leading to support for 6 more IMUs - with new delta angle and delta velocity feature: - ADIS16545-[1,2,3] - ADIS16547-[1,2,3] bosch,bmi160 - Support for the bmi120 IMU: ID only. Also relax ID checking to warn only on mismatch allowing use of fallback compatibles for new devices. sciosense,ens160 - New driver for this metal oxide multi-gas sensor for indoor air quality monitoring. sensortek,stk3110 - Support for stk3311a and stk3311s34 light sensor variants. Relax ID checking to warn only on a mismatch allowing use of fallback compatibles for new devices. vishay,veml6040 - New driver for this RGBW light sensor. Note that whilst the register interface is very different, the dt-binding similar enough that it is shared with the existing vishay,veml6075 binding x-powers,axp20x - Add support for axp192, very similar to another supported PMIC ADC variant but with a few more GPIO channels. Dt-binding only =============== ti,ads1015 - Add binding (no driver support yet) for ti,tla2021 New features ============ core - Variable scan type support. We have papered over this for a long time so good to finally resolve it. Some devices will change their data output format (typically resolution) dependent on settings such as oversampling. A new callback is added to enable this. First used in the ad7380 driver. - Harden the core against missing callback functions. dt-binding: - Add a single-channel property that can be used in per channel nodes instead of reg to indicate which device channel. This is important in devices with a mixture of differential and single ended channels as reg already just acted as an index for the differential channels making things inconsistent if it had more meaning for single ended channels. adi,ad7380 - Use spi_optimize_message() to reduce reading message setup overhead. - Add oversampling support using the new core functionality to allow a device support multiple scan types. invense,icm42600 - Support for low-power accelerometer modes. When a given sampling frequency is only supported at one power mode, use that. Otherwise default to low power at the cost of some noise unless overridden via a new sysfs attribute. silicon-labs,si70720 - Add control of the heater. Cleanups and minor fixes ======================== core - Cleanup use of sizeof(struct xxxx) in favor of sizeof(*variable) Makefile - Resort the iio/adc/Makefile which has drifted away from alphabetical order. gts library - Fix sorting of lists with a zero in the middle. Doesn't happen with upstream drivers, but good to harden this code. Add a related unit test. multiple drivers - Add missing MODULE_DESCRIPTION() - Drop some unused structure fields. - Drop some entirely unused structure definitions. - Stop pointless initialization of i2c_device_id::driver_data to 0 in drivers where it isn't used. - Use spi_get_device_match_data() to replace open-coded equivalent. adi,ad3552r - Fix dt gain parameter names to reflect what the driver does. Note discussion in patch to justify fixing it in the binding not the driver. - Tidy up some naming. adi,ad7192 - Use read_avail() callback to handle the low pass filter. - Add an aincom supply for pseudo differential operation. adi,ad7606 - Use iio_device_claim_direct_scoped() to simplify error paths. adi,ad7944 - Drop an unused function parameter. adi,adrf6780 - Drop unused header. adi,ad9467 - Use a DMA safe buffer for SPI transfers. - Stop using tabs to pad structure field names. It was creating a lot of noise. adi,axi-adc - Prevent races between enable and disable calls. - Ensure the DRP (dynamic reconfiguration port) is locked. Not used in most real designs, but better safe than sorry. - Limit build to COMPILE_TEST or platforms for which the IP exists. adi,axi-dac - Limit build to COMPILE_TEST or platforms for which the IP exists. ams,iaq - Use __packed instead of ___attribute__((__packed__)) bosch,bmp280 - White space cleanup. - Use BME280 prefix for registers that do not exist on the BMP280. - Add parameter names to callback function definitions. - Rename measure function to better reflect what it does which is wait for a measurement to happen. - Drop a redundant error check. - Improve error messages - Make error checks consistent as if (ret) - Use unsigned types for inherently unsigned data. - Refactor reading functions to not rely on a hidden t_fine variable. - Make use of cleanup.h freescale,mma7660 - Add mount matrix support. invense,icm42600 - Enable the regmap cache to reduce bus accesses. amlogic,meson-saradc - Add dt-binding support for power-domains. ti,adc161s626 - Use iio_device_claim_direct_scoped() to simplify error handling. * tag 'iio-for-6.11a' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (107 commits) iio: imu: inv_icm42600: add support of accel low-power mode iio: document inv_icm42600 driver private sysfs attributes MAINTAINERS: Add ScioSense ENS160 iio: chemical: ens160: add power management support iio: chemical: ens160: add triggered buffer support iio: chemical: add driver for ENS160 sensor dt-bindings: iio: chemical: add ENS160 sensor dt-bindings: vendor-prefixes: add ScioSense iio: temperature: mcp9600: add threshold events support dt-bindings: iio: light: add VEML6040 RGBW-LS iio: light: driver for Vishay VEML6040 dt-bindings: iio: adc: amlogic,meson-saradc: add optional power-domains iio: dac: adi-axi-dac: add platform dependencies iio: adc: adi-axi-adc: add platform dependencies iio: imu: inv_icm42600: add register caching in the regmap iio: adc: mcp3564: drop redundant open-coded spi_get_device_match_data() iio: dac: max5522: simplify with spi_get_device_match_data() iio: addac: ad74413r: simplify with spi_get_device_match_data() iio: adc: ti-tsc2046: simplify with spi_get_device_match_data() iio: adc: ti-ads131e08: simplify with spi_get_device_match_data() ...

Add ODRs accessible only in low-power mode. Switch automatically to low-power or low-noise depending on the ODR set. Add channel attributes "power_mode" and "power_mode_available" for setting the power mode to use (low-noise or low-power) for ODRs supporting both mode. Reading "power_mode" when the sensor is on will return the actual mode and not the requested one. It will be different when using ODRs not supported by the requested mode. Use low-power mode by default. Signed-off-by:

The device has four programmable temperature alert outputs which can be used to monitor hot or cold-junction temperatures and detect falling and rising temperatures. It supports up to 255 degree celsius programmable hysteresis. Each alert can be individually configured by setting following options in the associated alert configuration register: - monitor hot or cold junction temperature - monitor rising or falling temperature - set comparator or interrupt mode - set output polarity - enable alert This patch binds alert outputs to iio events: - alert1: hot junction, rising temperature - alert2: hot junction, falling temperature - alert3: cold junction, rising temperature - alert4: cold junction, falling temperature All outputs are set in comparator mode and polarity depends on interrupt configuration.

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. Signed-off-by:

This patch adds support for the integrated on-chip heater that is present on all the devices supported by this driver (si7020, si7021, si7013, th6). In order to configure the heater, the driver interacts with the following device registers: * User Register - the 2nd bit of this register is a "Heater Enable bit" (0 means that the heater is off, 1 means that it's on). * Heater Register - this register is present only on the si70xx devices and controls the current flowing through the heater. The 4 lower bits of this register can be assigned values from 0x0 to 0xF. Signed-off-by:

The ADIS16545 and ADIS16547 are a complete inertial system that includes a triaxis gyroscope and a triaxis accelerometer. The serial peripheral interface (SPI) and register structure provide a simple interface for data collection and configuration control. These devices are similar to the ones already supported in the driver, with changes in the scales, timings and the max spi speed in burst mode. Also, they support delta angle and delta velocity readings in burst mode, for which support was added in the trigger handler. Co-developed-by:
