Introduce ABI documentation for new modifiers used for reporting rotations expressed as euler angles (i.e. yaw, pitch, roll). It looks like we have some unit inconsistency along various IIO modifiers: it seems that incli is in deg, angl is in radians and rot isn't documented, but at least the adis16209 driver has rot in deg. Here we use deg (so angl is the only one using radians). Signed-off-by:

Add IIO_MOD_LINEAR_X, IIO_MOD_LINEAR_Y and IIO_MOD_LINEAR_Z modifiers to te IIO core, which is preparatory for adding the Bosch BNO055 IMU driver. Bosch BNO055 IMU can report raw accelerations (among x, y and z axis) as well as the so called "linear accelerations" (again, among x, y and z axis) which is basically the acceleration after subtracting gravity and for which those new modifiers are for.

The DPS310 chip has been observed to get "stuck" such that pressure and temperature measurements are never indicated as "ready" in the MEAS_CFG register. The only solution is to reset the device and try again. In order to avoid continual failures, use a boolean flag to only try the reset after timeout once if errors persist.

By default the driver was always setting the RANGE bit which means that the analog input goes from 0 to VREF. However, we might want to have 0 to 2xVREF. This change adds a new Firmware property to allow for the extended range while keeping the default behavior if nothing is provided. Signed-off-by:

Some of the supported devices have 4 or 2 LSB trailing bits that should not be taken into account. Hence we need to shift these bits out which fits perfectly on the scan type shift property. This change fixes both raw and buffered reads.

Set the iio device's name based on the chip used for the LTC2499 only. The most common way for IIO clients to interact with a device is to address it based on it's name. By using the dev_name() function, the name will be set based on a i2c_client's kobj name, which has the format i2c_instance-i2c_address (1-0076 for example). This is not ideal, since it makes a requirement for userspace to have knowledge about the hardware connections of the device. The name field is set to NULL for the LTC2497 and LTC2496, so that the old name can kept as it is, since changing it will result in an ABI breakage. Signed-off-by:

After the result of the previous conversion is read the chip automatically starts a new conversion and doesn't accept new i2c transfers until this conversion is completed which makes the function return failure. So add an early return iff the programming of the new address isn't needed. Note this will not fix the problem in general, but all cases that are currently used. Once this changes we get the failure back, but this can be addressed when the need arises. Fixes: 69548b7c ("iio: adc: ltc2497: split protocol independent part in a separate module ") Reported-by:

Simplified common initialization logic of different sensor types unifying calibration and initial configuration recovery. Default config param values of each sensor type are stored inside chip_info structure and used to initialize sensor data struct instance. The helper functions for read each sensor type calibration are converted to a callback available on the chip_info struct. Separated bme280 specific calibration code from bmp280 function. Dropped the additional chip_id argument in bmp280 code as is not longer required. Now both bmp280/bme280 calibration function use same signature as bmp180. Suggested-by:

Combined with Andy Shevchenko's long term work on drivers, this leaves IIO in a good state for handling other firmware types. New device support - liteon,ltrf216a * New driver and dt bindings to support this Light sensor. - maxim,max11205 * New driver for this 16bit single channel ADC. - memsensing,msa311 * New driver for this accelerometer. Includes a string helper for read/write. - richtek,rtq6056 * New driver and dt binding to support this current monitor used to measure power usage. - yamaha,yas530 * Support the YAS537 variant (series includes several fixes for other parts and new driver features). Staging graduation - adi,ad7746 CDC. Cleanup conducted against set of roadtest tests using the posted RFC of that framework. Features - core * Large rework to make all the core IIO code use generic firmware properties. Includes switching some drivers over as well using newly provided generic interfaces and allowing removal of DT specific ones. * Support for gesture event types for single and double tap. Used in bosch,bma400. - atmel,at91-sama5d2 * Add support for temperature sensor which uses two muxed inputs to estimate the temperature. * Handle trackx bits of EMR register to improve temp sampling accuracy. * Runtime PM support. - liteon,ltrf216a * Add a _raw channel output to allow working around an issue with differing conversions equations that breaks some user space controls. - mexelis,mlx90632 * Support regulator control. - ti,tsc2046 * External reference voltage support. Clean up and minor fixes - Tree-wide * devm_clk_get_enabled() replacements of opencoded equivalent. * Remaining IIO_DMA_MINALIGN conversions (the staging/iio drivers). * Various minor warning and similar cleanup such as missing static markings. * strlcpy() to strscpy() for cases where return value not checked. * provide units.h entries for more HZ units and use them in drivers. - dt-bindings cleanup * Drop maintainers listss where the email address is bouncing. * Switch spi devices over to using spi-peripheral.yaml * Add some missing unevaluatedProperties / additionalProperties: false entries. - ABI docs * Add some missing channel type specific sampling frequency entries. * Add parameter names for callback parameters. - MAINTAINERS * Fix wrong ADI forum links. - core * lockdep class per device, to avoid an issue with nest when one IIO device is the consumer of another. * White space tweaks. - asc,dlhl60d * Use get_unaligned_be24 to avoid some unusual data manipulation and masking. - atmel,at91-sama5d2 * Fix wrong max value. * Improve error handling when measuring pressure and touch. * Add locks to remove races on updating oversampling / sampling freq. * Add missing calls in suspend and resume path to ensure state is correctly brought up if buffered capture was in use when suspend happened. * Error out of write_raw() callback if buffered capture enabled to avoid unpredictable behavior. * Handle different versions having different oversampling ratio support and drop excess error checking. * Cleanup magic value defines where the name is just the value and hence hurts readability. * Use read_avail() callback to provide info on possible oversampling ratios. * Correctly handle variable bit depth when doing oversampling on different supported parts. Also handle higher oversampling ratios. - fsl,imx8qxp * Don't ignore errors from regulator_get_voltage() so as to avoid some very surprising scaling. - invensense,icp10100 * Switch from UNIVERSAL to DEFINE_RUNTIME_DEV_PM_OPS. UNIVERSAL rarely made sense and is now deprecated. In this driver we just avoid double disabling in some paths. - maxim,max1363 * Drop consumer channel map provision by platform data. There have been better ways of doing this for years and there are no in tree users. - microchip,mcp3911 * Update status to maintained. - qcom,spmi-adc5 * Support measurement of LDO output voltage. - qcom,spmi-adc * Add missing channel available on SM6125 SoC. - st,stmpe * Drop requirement on node name in binding now that driver correctly doesn't enforce it. - stx104 * Move to more appropriate addac directory - ti,am335x * Document ti,am654-adc compatible already in use in tree. - ti,hmc5843 * Move dev_pm_ops out of header and use new pm macros to handle export. - yamaha,yas530 * Minor cleanups. * tag 'iio-for-6.1a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (142 commits) iio: pressure: icp10100: Switch from UNIVERSAL to DEFINE_RUNTIME_DEV_PM_OPS(). iio: adc: max1363: Drop provision to provide an IIO channel map via platform data iio: accel: bma400: Add support for single and double tap events iio: Add new event type gesture and use direction for single and double tap iio: Use per-device lockdep class for mlock iio: adc: add max11205 adc driver dt-bindings: iio: adc: Add max11205 documentation file iio: magnetometer: yamaha-yas530: Use dev_err_probe() iio: magnetometer: yamaha-yas530: Make strings const in chip info iio: magnetometer: yamaha-yas530: Use pointers as driver data iio: adc: tsc2046: silent spi_device_id warning iio: adc: tsc2046: add vref support dt-bindings: iio: adc: ti,tsc2046: add vref-supply property iio: light: ltrf216a: Add raw attribute dt-bindings: iio: Add missing (unevaluated|additional)Properties on child nodes MAINTAINERS: fix Analog Devices forum links iio/accel: fix repeated words in comments dt-bindings: iio: accel: add dt-binding schema for msa311 accel driver iio: add MEMSensing MSA311 3-axis accelerometer driver dt-bindings: vendor-prefixes: add MEMSensing Microsystems Co., Ltd. ...
