First set of new device support, features and fixes for IIO in the 5.2 cycle Staging graduations * ad7780 - Move this ADC driver out of staging. Included adding some new features along the way (see below). Also added DT bindings. New device support * adis16480 - Support the ADIS16495 and ADIS16497 IMU devices making heavy use of refactoring of various aspects of the driver in precursor patches. * lsm6dsx - Support for the ASM330LHH 6-axis (accelerometer + gyro) sensor. - Support for the LSM6DS0X * matbotix mb1232 - New driver for this ultrasound ranging device family. Including bindings. - Supports mb1202, mb1212, mb1222, mb1232, mb1242, mb7040 and mb7137. * max31856 - New driver for this thermocouple temperature sensor. * meson saradc - Support the Meson-G12A (ID addition only). * stmpe-adc - New driver supporting generic ADC alongside touchscreen support which previously existed. Includes DT bindings. * vcnl4000 - Support for the vcln4040 proximity and light sensor, including adding DT bindings for this and parts previously supported. Features * core - Allow reading of mount matrices from ACPI in addition to DT. - Common binding for theromcouple types. * ad5933 - Add ABI docs as there are a few 'unsual' elements about this device - perhaps because it's our only impedance analyser. * ad7780 - Add gain and filter gpio support + readback of current gain and filter. * adis16480 - Allow selection fo the dataready pin to be used. - Device tree ID table and binding documentation. - Support external clock modes, including new bindings. * bma180 - Mount matrix support. * bmc150 - Mount matrix support. * bmg160 - Mount matrix support. - DT id table and bindings doc. * bmp280 - Put calibration data into the entropy pool. * hmc5843 - Mount matrix support. * itg3200 - Mount matrix support. * kxcjk1013 - Device tree id table, and binding docs. * lpc32xx - Add scale when regulator specified including DT docs for regulator. * pms7003 - Add device IDs for all supported parts to driver and binding. * stm32-dfsdm - Enable hw consumer support, scan mode control and a complex set of triggered buffer modes. - Power management. * stm32-lptimer-counter - power management. - Document the pinctrl sleep state binding. * ti-ads7950 - GPIO pin support. Cleanups, minor fixes * core - Use bitmap_zalloc to make it explicit that is what we are doing. - Tidy up all the Kconfig files (which had slowly gotten messy) - Fix a forwards definition missing issue in iio/driver.h * ad sigma delta core - Improve handling of SPI bus locking vs CS assertion. This has been wrong a long time so not rushing this in. * ad5064 - Mlock to local lock. * ad5933 (staging cleanup) - Multiline comment fixes. - Include ordering. - SPDX. - Tidy up Kconfig help which was a bit missleading. - Change some non standard attributes to ABI defined ones. * ad7124 - White space fix. * ad7192 - White space. - Use DT clock binding. - Improve error reporting. - Platform data to DT conversion. - Use read_avail callback, mostly to avoid the endless series of patches from new contributors trying to falsely put spaces around the negative sign. * ad7280a - Add brackets to macros to avoid potential precedence isseus. - Add temp vars for event codes to reduce indent and improved readability. - Clean out som CamelCase notation. - White space. * ad7606 - Fix broken file naming in MAINTAINERS. * ad7780 - Missing switch defaults to supress warnings and harden the code slightly. - Set pattern masks more directly. - Add ID values and masks for all supported chips. - SPDX + add Renato as a copyright holder as he has done a lot of work on this driver. - Add brackets to macros to avoid potential precedence issues. * ad7923 - White space fixes. - Use BIT macro to improve readability. - Add brackets to macros to avoid potential precedence issues. - Tidy up a null comparisom. * ad9523 - Fix a typo in naming of variables. * adis16400 - Combine trigger file into main code as no advantage in separate files. Rename core file to just adis16400. - Squash the header into the c file now there is only one file. - Generalize burst mode to support new variants. * ak8975 - Local variable to improve readability around mount matrix support. * as3935 - Avoid potential race by ensuring remove does exact opposite of probe rather than a slightly different order. * cross_ec - Drop some unnecessary includes. - Fix some warning and the slightly 'unusual' code. - Add some docs for non obvious function. - SPDX * hmc5843 - Potential unhandled error case. * iio trigger core - Print an error if there is no available irq due to max consumers per trigger being set to low. * iio loop trigger - Drop an unlikely on IS_ERR as IS_ERR already has the annotation. * ingenic-adc - Drop a redundant dev_err call as devm_ioremap_resource reports the same internally. * lmp91000 - Drop some unncessary parentheses and white space tidy up. - Invert and if statement to improve readability. - Fix a wrong error message. * lpc32xx - Header sorting + drop some unused ones. * mma8542 - Mark a switch fallthrough. * mpu6050 - Add a local variable to improve code readability around mount matrix support. * mxs-lradc-adc - Handle devm_iio_trigger_alloc failure. * sps30 - Fix up a kernel version in the ABI docs. * srf04 - DT binding doc converted to yaml. * ssp_sensors - Supress a clang build warning due to lack of visibility of conditional within a iio_push_to_buffers_with_timestamp. (reasonable false warning!) * st_accel - Drop pointless less than 0 comparisom of unsigned int. * stm32-dfsdm - Improve accuracy of spi_master_frequency calculation. - Improve calculation fo sampling frequency. - Rework various internals to simplify adding triggered buffer support. - Claim direct mode to avoid racing around read_raw and being in buffered mode. * stmpe - Fix a clang false positive warning. * ti-ads7950 - Use local lock rather than using the core mlock when not locking around the device mode. * vcnl4000 - Use word writes instead of byte writes. It seems byte writes are fine for some parts (undocument) but not others that the driver will shortly support. Other * mailmap - Add email address change for Sean Nyekjaer. Update in relevant drivers
