Jonathan writes: First set of new device support, features and cleanups for IIO in the 5.4 cycle Note includes a merge from i3c tree to get support needed for stm_lsm6dsx driver support for l3c devices. Done from immutable branch. A counter subsystem patche in here as well. Alongside the new device support (which is always good), Chuhong's work on using devres managed APIs has cleaned up a number of drivers. New device support * adis16460 - New driver based on ADIS framework which needed addition of support for cs_change_delay. Includes device tree binding. * cros_ec - Support fo the veyron-minnie which uses an older interface. * lsm6dsx - Support for LSM6DSTR-C gyro + magnetometer sensor (new IDs mainly) - Support for ISM330DHCX acc + gyro sensor (extensive rework needed!) * Maxim 5432 - New driver support MAX5432-MAX5435 family of potentiometers. * noa1305 - New driver for this ON Semiconductor Ambient light sensor. Features and cleanups * tree wide - Drop error prints after platform_get_irq as already prints errors internally if any occur. * docs - Document mounting matrix. - Fix a missing newline at end of file. * ad2s1210 - Switch to device managed APIs for all of probe and drop explicit remove. * ad7192 - Add of_device_id array to explicity handling DT bindings. * ad7606 - Lots of rework leading to support for software configure modes in ad7616 parts. - Debugfs register access support. * am2315 - Switch to device managed APIs for all of probe and drop explicit remove. * apds9960 - Typo in module description. * cm36651 - Convert to i2c_new_dummy_device. - Swithc to device managed APIs for all of probe adn drop explicit remove. * cros_ec - Calibscale support for accel, gyro and magnetometer. - Tidy up some error codes to return the error from the stack rather than -EIO. - Determine protocol version. - Add a sign vector to the core to fix sensor rotation if necessary. Cannot just be done with mount matrix as already in use in many devices. - Tidy up INFO_SCALE being in both the separate and shared lists. - Drop a lot of dplicate code from the cros-ec-accel-legacy driver and use the core provided code instead. - Make frequency range available to userspace. * counter / ftm-quaddec - Switch to device managed APIs for all of probe adn drop explicit remove. * hdc100x - Switch to device managed APIs for all of probe and drop explicit remove. * hi8435 - Use gpiod_set_value_cansleep as we don't care here and there is a board out there where it needs to sleep. - Switch to device managed APIs for all of probe and drop explict remove. * hp03 - Convert to i2c_new_dummy_device. * maxim thermocouple - Switch to device managed APIs for all of probe and drop explicit remove. * mmc35240 - Fix typo in constant naming. * mpu6050 - Use devm_add_action_or_reset in place of explicit error handling. - Make text in Kconfig more explicit about which parts are supported. * mxc4005 - Switch to device managed APIs for all of probe and drop explicit remove. * pms7003 - Convert device tree bindings to yaml. - Add a MAINTAINERS entry * sc27xx - Introduce a local struct device *dev pointer to avoid lots of deref. - Use devm_add_action_or_reset in place of explicit error handling. * sca3000 - Typo fix in naming. * si1145 - Switch to device managed APIs for all of probe and drop explicit remove. * st_sensors - Lots of rework to enable switch to regmap. - Regmap conversion at the end. - Tidy up some inconsistencies in buffer setup ops. - Tidy up an oddity by dropping get_irq_data_ready function in favour of direct access. - Stop allocating buffer in buffer enable in favour of just embedding a large enough constant size buffer in the iio_priv accessed structure. * st_lsm6dsx - l3c device support (LSM6DSO and LSM6DSR) - tidy up irq return logic which was strangely written. - fix up an ABI quirk where this driver used separate scale attributes, even though they were always shared by type. * stk33xx - Device tree bindings include manufacturer ID. * stm32-adc - Add control for supply to analog switches including DT bindings. * stm32 timer - Drop the quadrature mode support. Believed there were no users so take this opportunity to drop this unwanted ABI. * tsl2772 - Switch to device mangage APIs for all of probe and drop explicit remove. - Use regulator_bulk_* APIs to reduce repitition. * veml6070 - Convert to i2c_new_dummy_device. * tag 'iio-for-5.4a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (84 commits) iio: hi8435: Drop hi8435_remove() by using devres for remaining elements iio: hi8435: Use gpiod_set_value_cansleep() iio:st_sensors: remove buffer allocation at each buffer enable iio: imu: inv_mpu6050: be more explicit on supported chips iio: light: noa1305: Add support for NOA1305 dt-bindings: Add binding document for NOA1305 iio: remove get_irq_data_ready() function pointer and use IRQ number directly iio: imu: st_lsm6dsx: make IIO_CHAN_INFO_SCALE shared by type iio: tsl2772: Use regulator_bulk_() APIs iio: tsl2772: Use devm_iio_device_register iio: tsl2772: Use devm_add_action_or_reset for tsl2772_chip_off iio: tsl2772: Use devm_add_action_or_reset iio: Remove dev_err() usage after platform_get_irq() iio: light: si1145: Use device-managed APIs iio:pressure: preenable/postenable/predisable fixup for ST press buffer iio:magn: preenable/postenable/predisable fixup for ST magn buffer iio:gyro: preenable/postenable/predisable fixup for ST gyro buffer iio:accel: preenable/postenable/predisable fixup for ST accel buffer dt-bindings: iio: imu: st_lsm6dsx: add ism330dhcx device bindings iio: imu: st_lsm6dsx: add support to ISM330DHCX ...
