| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For reliable operation across the full range of supported interface rates, the AD5593R needs a STOP condition between address write, and data read (like show in the datasheet Figure 40) so in turn i2c_smbus_read_word_swapped cannot be used. While at it, a simple helper was added to make the code simpler.

* | i2c: Make remove callback return voidUwe Kleine-König2022-08-168-24/+8
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

Stand out this time is Andy Shevchenko's continuing effort to move drivers over the generic firmware interfaces. Device support * sprd,sc2720 - upm9620 binding addition. - Refactor and support for sc2720, sc2721 and sc2730. * ti,ads1015 - Refactor driver and add support for TLA2024. Device support (IDs only) * invensense,mpu6050 - Add ID for ICM-20608-D. * st,accel: - Add ID for lis302dl. * st,lsm6dsx - Add support for ASM330LHHX (can fallback to LSM6DSR.) Features * convert drivers to device properties - IIO core - adi,ad7266 - adi,adis16480 - adi,adxl355 - bosch,bmi160 - domintech,dmard06 - fsl,fxas21002c - invensense,mpu3050 - linear,ltc2983 - linear,ltc2632 - maxbotix,mb1232 - maxim,max31856 - maxim,max31865 - multiplexer - ping - rescale - taos,tsl2772 * core - Add runtime check on whether realbits fit in storagebits for each channel. * adi,ad_sigma_delta - Add sequencer support and relevant update_scan_mode callbacks for adi,ad7192 and adi,ad7124. Cleanup and minor fixes * MAINTAINERS - Update Lorenzo Bianconi's email address for IIO drivers. - Add entry for ad3552r and update maintainer in dt-binding doc. * tree-wide - Replace strtobool() with kstrtobool(). - Drop false OF dependencies. * core - Tidy up and document IIO modes. - Take iio_buffer_enabled() out of header allowing current_mode to be moved to the opaque structure. - As all kfifo buffers use the same mode value, drop that parameter and set it unconditionally. - White space fixes and similar. - Drop use of list iterator variable for list_for_each_entry_continue_reverse and use list_prepare_entry to restart. * sysfs-trigger - Replace use of 'found' variable with dedicate list iterator variable. * adi,ad7124 - Drop misleading shift. * adi,ad2s1210 - Remove redundant local variable assignment. * adi,adis16480 - Use local device pointer to reduce repetition. - Improve handling of clocks. * domintech,dmard09 - White space. * dummy driver - Improve error handling. * fsl,mma8452 - Add missing documentation of name element. * invensense,mpu3050 - Stop remove() returning non 0. * kionix,kxsd9 - White space. * linear,ltc2688 - Use local variable for struct device. - Combine of_node_put() error handling paths. * linear,ltc2983 - Avoid use of constants in messages where a define is available. * microchip,mcp4131 - Fix compatible in dt example. * pni,rm3100 - Stop directly accessing iio_dev->current_mode just to find out if the buffer is enabled. * renesas,rzg2l - Relax kconfig constraint to include newer devices. * sprd,sc27xx - Fix wrong scaling mask. - Improve the calibration values. * samsung,ssp - Replace a 'found' variable in favor of an explicit value that was found. * sensortek,stk3xx - Add proximity-near-level binding and driver support. * st,st_sensors: - Drop unused accel_type enum. - Return early in *_write_raw() - Drop unnecessary locking in _avail functions. - Add local lock to protect odr against concurrent updates allowing mlock to no longer be used outside of the core. - Use iio_device_claim_direct_mode() rather than racy checking of the current mode. * st,stmpe-adc - Fix checks on wait_for_completion_timeout(). - Allow use of of_device_id for matching. * st,stm32-dfsdm - Stop accessing iio_dev->current_mode to find out if the buffer is enabled (so we can hide that variable in the opaque structure) * st,vl53l0x - Fix checks on wait_for_completion_timeout. * ti,ads1015 - Add missing ID for ti,ads1115 in binding doc. - Convert from repeated chip ID look up to selecting static const data. - Switch to read_avail() callback. * ti,ads8688 - Use of_device_id for driver matching. * ti,palmas-adc - Drop a warning on minor calibration mismatch leading to slightly negative values after applying the calibration. * tag 'iio-for-5.19a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (95 commits) iio: ti-ads8688: use of_device_id for OF matching iio: stmpe-adc: use of_device_id for OF matching dt-bindings: iio: Fix incorrect compatible strings in examples iio: gyro: mpu3050: Make mpu3050_common_remove() return void iio: dac: ltc2632: Make use of device properties iio: temperature: max31865: Make use of device properties iio: proximity: mb1232: Switch to use fwnode_irq_get() iio: imu: adis16480: Improve getting the optional clocks iio: imu: adis16480: Use temporary variable for struct device iio: imu: adis16480: Make use of device properties staging: iio: ad2s1210: remove redundant assignment to variable negative iio: adc: sc27xx: add support for PMIC sc2730 iio: adc: sc27xx: add support for PMIC sc2720 and sc2721 iio: adc: sc27xx: refactor some functions for support more PMiCs iio: adc: sc27xx: structure adjustment and optimization iio: adc: sc27xx: Fine tune the scale calibration values iio: adc: sc27xx: fix read big scale voltage not right dt-bindings:iio:adc: add sprd,ump9620-adc dt-binding iio: proximity: stk3310: Export near level property for proximity sensor dt-bindings: iio: light: stk33xx: Add proximity-near-level ...
