Merge tag 'iio-for-6.1b' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next
Jonathan writes: Second set of IIO new device support, features and cleanup for the 6.1 cycle. Normal mixed bag of new device support with continuing trend that most new devices are supported by extending existing drivers - a positive sign perhaps that device manufacturers have somewhat stabilized their interfaces across product generations. The BNO055 driver was however a substantial addition including several additions to the IIO core. There are a number of significant patch sets under review, so if the 6.0 cycle runs long I may send a 3rd pull request. New device support * adi,adxl313 - Support for the ADXL312 and ADXL314 accelerometers. * bosch,bmp280 - Support for the BMP380 family of pressures sensors. Included considerable refactoring and modernization of the bmp280 driver. * bosch,bno055 - New driver for this i2c/serial attached complex IMU. * lltc,ltc2497 - Support for the LTC2499 16 channel, 24bit ADC. * st,pressure - Support for the LPS22DF pressure sensor * st,lsm6dsx - Support for the LSM6DSTX (Mainly adding the ID and WAI) Features * core - to support the bosch,bno055 requirements - Support for linear acceleration channel type (effect of gravity removed) - Pitch, yaw and roll modifiers for angle channels. - Standard serialnumber attribute documentation. - Binary attributes - to allow for calibration save and restore. * adi,ad7923 - Support extended range (wider supported input voltage range). * bosch,bmp280 - Add filter controls for some supported parts. * microchip,mcp3911 - Buffered capture support for this ADC. - Data ready interrupt support, including hiz control for line. - Oversampling ratio support. * st,stm32-adc - Support ID registers on parts where they are present, providing discoverability of some features. Fixes - late breaking fixes that I judged could wait for the merge window. * adi,ad5593r - Add a missing STOP condition between address write and data read. - Check for related i2c functionality. * adi,ad7923 - Fix shift reporting for some variants supported by the driver. * infinion,dps310 - Work around a hardware issue where a chip can hang by adding a timeout and reset path. Cleanups * Continuing work to switch to new pm macros. * MAINTAINERS - Drop duplication of wild card covered entry in ADI block and add missing entries to cover ltc294x binding files. * bosch,bma400 - Fix trivial smatch warning. * bosch,bmp280 - Fix broken links to datasheets * lltc,ltc2497 - Fix missing entry for ltc2499 * mexelis,mlx90614 - Switch to get_avail() callback for _available attributes. * microchip,mcp3911 - Move to devm_ resource management for all elements of probe() * tag 'iio-for-6.1b' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (57 commits) iio: adc: mcp3911: add support for oversampling ratio dt-bindings: iio: adc: mcp3911: add microchip,data-ready-hiz entry iio: adc: mcp3911: add support for interrupts iio: adc: mcp3911: add support for buffers iio: adc: mcp3911: use resource-managed version of iio_device_register iio: accel: bma400: Fix smatch warning based on use of unintialized value. iio: light: st_uvis25: Use EXPORT_NS_SIMPLE_DEV_PM_OPS() iio: accel: bmi088: Use EXPORT_NS_GPL_RUNTIME_DEV_PM_OPS() and pm_ptr() iio: proximity: srf04: Use pm_ptr() to remove unused struct dev_pm_ops iio: proximity: sx9360: Switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() iio: proximity: sx9324: Switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() iio: proximity: sx9310: Switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() docs: iio: add documentation for BNO055 driver iio: imu: add BNO055 I2C driver iio: imu: add BNO055 serdev driver dt-bindings: iio/imu: Add Bosch BNO055 iio: document "serialnumber" sysfs attribute iio: document bno055 private sysfs attributes iio: imu: add Bosch Sensortec BNO055 core driver iio: add support for binary attributes ...
