Merge tag 'iio-for-5.14a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: 1st set of new IIO/counter device support, features and cleanup for 5.14 There are a couple of large cleanup sets in here alongside a number of new drivers. Note an immutable branch merged to add a stub for i2c_verify_client() as needed to avoid a build issue in the fxls8962af driver as a result of a workaround for a device errata that only applies when i2c interface is used. Counters ======== New device support * intel,quadrature encoder peripheral found on Elkhart Lake platforms. - New driver. IIO === New device support * amstaos,tsl2591 ambient light sensor. - New driver + bindings - Follow up fix to ensure some local variables are suitable for error handling. * fsl,fxls8962af + fsl,fxls8964af accelerometers - New driver + bindings - Includes an errata work around that cause a build bot failure fixed by adding a stub to i2c. * kionix,kxcjk-1013 - Add support for KX023-1025 device. Mostly a different register map that needed to be supported. * murata,sca3300 accelerometer - New driver + bindings * st,lsm9ds0 IMU - Rework of st,sensors driver to cleanly support this new glue driver that enables the two parts of the LSM9DS0. * ti,tsc2046 touchscreen controller ADC. - New driver. Intent here is to use this with existing IIO consumer drivers such as resistive-adc-touch. - Follow up fix to avoid an issue with unsigned subtraction in error check. * ti,tmp117 digital temperature sensor - New driver + bindings Features * adi,ad5755 - Add missing dt-binding doc * adi,ad7298 - Add ACPI ID used on Intel Galileo Gen 1 boards. - Add missing dt-binding doc * adi,ad7476 - Add missing dt-binding doc * adi,ad7746 - Add missing dt-binding doc for this driver that will hopefully move out of staging shortly. Update staging driver to use the binding instead of platform data. * adi,adis16201 + adis16209 - Add missing dt-binding doc * adi,adis16480 - Support burst mode for adis16495 and adis16497 parts. * bosch,bma220 - Add missing dt-binding doc * fsl,mma7455 - Add missing dt-binding doc * iio-rescale - Support handling of processed channels from provider. Some ADCs require (typically non linear) calibration functions to be applied, and so provide only IIO_CHAN_INFO_PROCESSED read back. They can be used as providers to the iio-rescale driver which needs to handle them somewhat differently from IIO_CHAN_INFO_RAW * sensiron,sps30 - Support the serial interface. Note this required significant refactoring of existing driver. * st,st-sensors - Add mount matrix support for normal dt-binding whilst continuing to support the odd ACPI approach for accelerometers. * ti,dac082s085 + similar - Add missing dt-binding doc * trivial-devices - add entries for - memsic,mx4005, memsic,mx6255 and memsic,mxc6655 - sensortek,stk8312 and sensortek,stk8ba50 Cleanup / minor fixes * core - Use devm_add_action_or_reset() to replace boilerplate in several driver and core IIO devm_* functions. - Fix an error path issue introduced by above, that could return an error pointer rather than the expected null from dev_iio_device_alloc() - Move more IIO internals related fields from struct iio_dev to struct iio_dev_opaque. - Drop unused final update of in_loc in demux setup. * Docs - Move some docs from driver specific to core dos to avoid replication of names which the documentation builder does not allow. Note this means adding a few device specific notes to the general docs to cover the more unusual uses of the ABI. - ABI: Move old buffer/* and scan_elements/* docs to obsolete as now we have the bufferX/* variant. Not we are not getting rid of these interfaces, just encouraging new code to use the new interface. * IIO wide: - Tidy up new cases of dev.parent etc being set in drivers as the core now does it. - Fix more cases of possible miss-aligned buffers when passed to iio_push_to_buffers_with_timestamp(). Note we only have one known instance of anyone seeing this bug actually happening, so this has been a low priority cleanup effort for several cycles. - sysfs_emit() used in more drivers. - Runtime pm tidy up and use of pm_runtime_resume_and_get() - Buffer alignment fixes as iio_push_to_buffers_with_timestamp requires that the timestamp when inserted by naturally aligned + consumers can assume that all fields are naturally aligned. Part of a long running effort, with at least 2 more series to come tackling additional variants. - Stop specifying "mount-matrix" property name in every lookup of the mount matrix from firmware by hard coding it in the core. * adi,ad7476 - Handle the variety of different regulators used by the parts supported by this driver (came up in dt-binding review) * adi,ad7746 - Trivial drop of if (ret) return ret; return 0; pattern - Tidy up comments - Pull capdac setup out to own function. * adi,ad7766 - Trivial drop of if (ret) return ret; return 0; pattern * adi,adis - Avoid returning error codes in interrupt handlers. - Handle a failure in spi_write in the trigger handler. - Rework to add updating of device page after changing it. - Don't push data to IIO buffers when read failed. - Add configuration of burst max speed to core avoid handling this in each driver. - Use the adis_dev_lock() helper in adis16260 and adis16136 drivers. - Excessive includes cleanup via include-what-you-use static checker after zero day highlighted that these needed updating. * afe - Amend binding to add #io-channel-cells, thus allowing this IIO consumer to also be an IIO provider. * aosong,am2315 - Drop ACPI id. Unlikely this one is in the wild and it isn't valid ACPI naming. * bosch,bma180 - Adding missing bandwidth settings (500, 1000 Hz) * bosch,bme680 - Drop ACPI id. Unlikely this one is in the wild and it isn't valid ACPI naming. * ep93xx_adc, - Drop a redundant error print. * maxim,max118 - Convert remainder of probe() to devm_ managed functions. - Avoid some repeated jumping back and forth between iio_dev and spi structures. * maxim,max11100 - Use get_unaligned_be16() instead of open coding. - Convert remainder of probe() to devm_ managed functions. * samsung,exynos_adc - Unused error value dropped. * sensiron,sgp30 - Drop use of %hx in favor of %x and letting the normal type conversion work. * sensortek,stk8312 - Add lowercase device id and note uppercase version deprecated. - Drop ACPI id. Unlikely this one is in the wild and it isn't valid ACPI naming. * sprx,sc72xx_adc - add MODULE_DEVICE_TABLE * st,lsm6dsx - Fix docs of valid ODRs * st,sensors - dt-binding rework. Two efforts on this crossed in a previous cycle so this update cherry picks the best of the two yaml conversions. - Don't copy the channel spec array as now ext_info is no longer modified. * st,stm32-adc - tidy up some docs that were marked as kernel-doc but aren't. * ti,adc081c, ti,adc0832, ti,adc108s102 and ti,adc161s626 - Convert remainder of probe() functions to devm_ managed functions to simplify error handing and remove paths. * tag 'iio-for-5.14a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (171 commits) i2c: core: Add stub for i2c_verify_client() if !CONFIG_I2C iio: adis: Cleanout unused headers iio: accel: bma180: Add missing 500 Hz / 1000 Hz bandwidth counter: Add support for Intel Quadrature Encoder Peripheral staging: iio: cdc: ad7746: extract capac setup to own function staging: iio: cdc: ad7746: clean up probe return staging: iio: cdc: ad7746: remove ordinary comments iio: adc: ti-adc161s626: Use devm managed functions for all of probe. iio: adc: ti-adc108s102: Use devm managed functions for all of probe() iio: adc: ti-adc0832: Use devm managed functions for all of probe() iio: adc: ti-adc081c: Use devm managed functions for all of probe() iio: adc: max1118: Avoid jumping back and forth between spi and iio structures iio: adc: max1118: Use devm_ managed functions for all of probe iio: adc: max11100: Use devm_ functions for rest of probe() iio: adc: max11100: Use get_unaligned_be16() rather than opencoding. iio: chemical: sgp30: Drop use of %hx in format string. iio: gyro: st_gyro: Support mount matrix iio: magnetometer: st_magn: Support mount matrix iio: accel: st_sensors: Stop copying channels iio: accel: st_sensors: Support generic mounting matrix ...
