Jonathan writes: First set of IIO new device support, features and cleanup for 5.19 Usual mixed bag. 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 ...

iio: imu: adis16480: Improve getting the optional clocks

2022-04-28T18:22:56Z

The extended clocks are optional and may not be present for some configurations supported by this driver. Nevertheless, in case the clock is provided but some error happens during its getting, that error handling should be done properly. Use devm_clk_get_optional() API and report possible errors using dev_err_probe() to handle properly -EPROBE_DEFER error.

iio: imu: st_lsm6dsx: add support to ASM330LHHX

2022-04-28T18:22:54Z

Add support to STM ASM330LHHX (acc + gyro) automotive Mems sensor. The ASM330LHHX sensor can use LSM6DSR as fallback device since it implements all the ASM330LHHX features currently implemented in st_lsm6dsx.

iio: imu: inv_icm42600: Fix I2C init possible nack

2022-04-16T14:03:58Z

This register write to REG_INTF_CONFIG6 enables a spike filter that is impacting the line and can prevent the I2C ACK to be seen by the controller. So we don't test the return value.

iio: core: Simplify the registration of kfifo buffers

2022-04-10T15:25:46Z

Among all the users of the kfifo buffers, no one uses the INDIO_BUFFER_HARDWARE mode. So let's take this as a general rule and simplify a little bit the internals - overall the documentation - by eliminating unused specific cases. Use the INDIO_BUFFER_SOFTWARE mode by default with kfifo buffers, which will basically mimic what all the "non direct" modes do.

iio: imu: inv_mpu6050: Add support for ICM-20608-D

2022-04-04T08:11:24Z

The difference between the ICM-20608-D and the other ICM-20608 variants is the addition of a DMP (Digital Motion Processor) core. This difference is deemed substantial enough to change the WHOAMI register value. Since this driver doesn't currently acknowledge the exisence of something like a DMP core, simply copy ICM-20608 except for the aforementioned WHOAMI register.
