https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: 1st set of IIO new device support, feature and cleanup for 6.2 (take2) We have finally managed to take the mlock mutex entirely private so as to avoid it being used for multiple purposes. Now it is just used to protect device mode transitions (typically to and from buffered capture). Includes merge of an immutable i2c branch to get the new i2c_client_get_device_id() (thanks to Wolfram for providing the branch). Based on rc3 to pick up some precursor fixes from early in the cycle and avoid an unnecessarily messy history. New device support * adi,ad4310 - New driver to support this very flexible measurement device including a 24 bit ADC. Later fix for documentation build issue. * adi,adxl355 - Add support of the ADXL359 accelerometer. * adi,ltc2983 - Support additional variants of the temperatures sensor: LTC2984 with an EEPROM LTC2985, LTC2986 with only 10 channels. * invensense,icm42600 - Add support for icm42631 (needed only ID and WHOAMI) * kionix,kx022a - New driver for this 3 axis accelerometer. * maxim,max11401 - New driver to support this 24-bit 10 channel ADC. Includes some new ABI to support configuration of notch filters. * mediatek,mt6370 - Add new driver to support the ADC part of the mt6370. * st,lsm6dsx - Add support for LSM6DSV accelerometer and gyroscope. Simple additional of chip specific data and IDs. - Add support for LSM6DSV16X accelerometer and gyroscope. Compatible with features currently implemented for the LSM6DSV. * st,stm32-adc - Add support for stm32pm13x SoCs. core / subsystem wide: - Add new IIO_STATIC_CONST_DEVICE_ATTR() which is a dance necessary to allow for the wrapping of attributes in the code that duplicates them for multiple buffers. - Harden against future issues with expectation that all buffer attributes are iio_dev_attrs by changing the code to take an array of pointers of the correct type. - Last transitions of drivers to local locks rather than missuses of mlock. - Add an iio_device_claim_buffer_mode() callback to avoid a race in the max30100 driver without directly using mlock. - Move mlock to the opaque IIO device structure to prevent misuse. - Add missing spi_device_id tables to support auto loading of modules. - Update some ADI maintainers in DT bindings. - A few more moves of bus drivers and core module sets to export name spaces. - Extensive use of new devm_regulator_get_enable() and friends. - Switch a bunch of i2c drivers to probe_new() including the bmp280 which makes use of the new i2c_client_get_device_id() helper to simplify this change. dt-bindings: - More use of spi-peripheral-props.yaml. Features * freescale,mpl115 - Use runtime PM to implement shutdown GPIO support. * melexis,mlx90632 - More sophisticated runtime power management - Provide access to sampling frequency. - Trivial follow up fixes. * microchip,mcp3911 - Support control of PGA. * st,lsm6dsx - Add support for software triggers for cases where the IRQ lines are not wired up. * vishay,vcnl4000 - Add control of integration time. Minor cleanups and fixes * adi,ad4130 - Improve ABI documentation formatting. - Kconfig dependency fixup. * adi,ad5758 - Minor dt binding fix. * adi,ad9834 - Tidy up line breaks. * adi,ade7854 - Minor improvement in code clarity by replacing a ternary. * adi,admv8818 - Harden code against hardware returning wrong values. * adi,adxl355 - Warn only if unknown device ID detected to allow for fall back device tree compatibles on future devices. * adi,ltc2983 - dt-bindings clarifications and general improvements. - Ensure DMA safe buffer for bulk writes without relying on current regmap implementation choices. * avago,adps9960 - Fix up a disconnect between event enable attributes and what was enabled. * bosch,bma400 - Switch to dev_err_probe() from open coded EPROBE_DEFER handling. * cosmic,cc10001 - Fully devm managed probe() and related tidying up. * meas,ms5611 - Add an example of spi-max-frequency. * meleixs,mlx90632 - Tidy up confusing error return value. - Style improvements. * multiplexer - Switch to dev_err_probe() from open coded EPROBE_DEFER handling. * qcom,spmi-vadc - Minor dt binding improvements. * rockchip,saradc - Add ID for rv1126. * semtech,sx9360 - Add SAMM0208 ACPI ID. Doesn't appear to be a valid vendor prefix but is in the wild. * st,lsm6dsx - Factor out common code as _device_set_enable(). - Fix up wrong docs after LSM6DSV addition. * st,stm32-adc - Manage the min sampling time on all internal channels. * trig,sysfs - Improve error labels. * tag 'iio-for-6.2a-take2' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (146 commits) iio: pressure: bmp280: convert to i2c's .probe_new() iio: imu: st_lsm6dsx: fix LSM6DSV sensor description iio: adc: ad4130: depend on GPIOLIB staging: iio: meter: replace ternary operator by if condition iio: light: apds9960: Fix iio_event_spec structures dt-bindings: iio: imu: Add inv_icm42600 documentation iio: imu: inv_icm42600: Add support for icm42631 dt-bindings: iio: adc: rockchip-saradc: Add saradc for rv1126 dt-bindings: iio: dac: adi,ad5758: Drop 'contains' from 'adi,dc-dc-mode' dt-bindings: iio: imu: st_lsm6dsx: add lsm6dsv16x iio: imu: st_lsm6dsx: add support to LSM6DSV16X iio: proximity: sx9360: Add a new ACPI hardware ID iio: temperature: mlx90632: Add missing static marking on devm_pm_ops iio: temperature: mlx90632: Add error handling for devm_pm_runtime_enable() iio: temperature: ltc2983: support more parts dt-bindings: iio: temperature: ltc2983: support more parts dt-bindings: iio: temperature: ltc2983: use generic node name in example dt-bindings: iio: temperature: ltc2983: describe broken mux delay property dt-bindings: iio: temperature: ltc2983: refine descriptions dt-bindings: iio: temperature: ltc2983: change default excitation for custom thermistors ...

2022-11-23iio: adis: add '__adis_enable_irq()' implementationRamona Bolboaca1-18/+10
Add '__adis_enable_irq()' implementation which is the unlocked version of 'adis_enable_irq()'. Call '__adis_enable_irq()' instead of 'adis_enable_irq()' from '__adis_intial_startup()' to keep the expected unlocked functionality. This fix is needed to remove a deadlock for all devices which are using 'adis_initial_startup()'. The deadlock occurs because the same mutex is acquired twice, without releasing it. The mutex is acquired once inside 'adis_initial_startup()', before calling '__adis_initial_startup()', and once inside 'adis_enable_irq()', which is called by '__adis_initial_startup()'. The deadlock is removed by calling '__adis_enable_irq()', instead of 'adis_enable_irq()' from within '__adis_initial_startup()'.

2022-09-21iio: imu: add Bosch Sensortec BNO055 core driverAndrea Merello6-0/+1707
Add the core driver for the BNO055 IMU from Bosch. This IMU can be connected via both serial and I2C busses; separate patches will add support for them. The driver supports "AMG" (Accelerometer, Magnetometer, Gyroscope) mode, that provides raw data from the said internal sensors, and a couple of "fusion" modes (i.e. the IMU also does calculations in order to provide euler angles, quaternions, linear acceleration and gravity measurements). In fusion modes the AMG data is still available (with some calibration refinements done by the IMU), but certain settings such as low pass filters cut-off frequency and sensors' ranges are fixed, while in AMG mode they can be customized; this is why AMG mode can still be interesting.

2022-08-16i2c: Make remove callback return voidUwe Kleine-König2-6/+2
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.

https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: IIO new device support, features and minor fixes for 5.20 Several on-running cleanup efforts dominate this time, plus the DMA safety alignment issue identified due to improved understanding of the restrictions as a result of Catalin Marinas' efforts in that area. One immutable branch in here due to MFD and SPMI elements needed for the qcom-rradc driver. Device support * bmi088 - Add support for bmi085 (accelerometer part of IMU) - Add support for bmi090l (accelerometer part of IMU) * mcp4922 - Add support for single channel device MCP4921 * rzg2l-adc - Add compatible and minor tweaks to support RZ/G2UL ADC * sca3300 - Add support for scl3300 including refactoring driver to support multiple device types and cleanup noticed whilst working on driver. * spmi-rradc - New driver for Qualcomm SPMI Round Robin ADC including necessary additional utility functions in SPMI core and related MFD driver. * ti-dac55781 - Add compatible for DAC121C081 which is very similar to existing parts. Features * core - Warn on iio_trigger_get() on an unregistered IIO trigger. * bma400 - Triggered buffer support - Activity and step counting - Misc driver improvements such as devm and header ordering * cm32181 - Add PM support. * cros_ec - Sensor location support * sx9324 - Add precharge resistor setting - Add internal compensation resistor setting - Add CS idle/sleep mode. * sx9360 - Add precharge resistor setting * vl53l0x - Handle reset GPIO, regulator and relax handling of irq type. Cleanup and minor fixes: Treewide changes - Cleanup of error handling in remove functions in many drivers. - Update dt-binding maintainers for a number of ADI bindings. - Several sets of conversion of drivers from device tree specific to generic device properties. Includes fixing up various related header and Kconfig issues. - Drop include of of.h from iio.h and fix up drivers that need to include it directly. - More moves of clusters of drivers into appropriate IIO_XXX namespaces. - Tree wide fix of a long running bug around DMA safety requirements. IIO was using __cacheline_aligned to pad iio_priv() structures. This worked for a long time by coincidence, but correct alignment is ARCH_KMALLOC_MINALIGN. As there is activity around this area, introduce an IIO local IIO_DMA_MINALIGN to allow for changing it in one place rather than every driver in future. Note, there have been no reports of this bug in the wild, and it may not happen on any platforms supported by upstream, so no rush to backport these fixes. Other cleanup * core - Switch to ida_alloc()/free() - Drop unused iio_get_time_res() - Octal permissions and DEVICE_ATTR_* macros. - Cleanup bared unsigned usage. * MAINTAINERS - Add include/dt-bindings/iio/ to the main IIO entry. * ad5380 - Comment syntax fix. * ad74413r - Call to for_each_set_bit_from(), with from value as 0 replaced. * ad7768-1 - Drop explicit setting of INDIO_BUFFER_TRIGGERED as now done by the core. * adxl345 - Fix wrong address in dt-binding example. * adxl367 - Drop extra update of FIFO watermark. * at91-sama5d2 - Limit requested watermark to the hwfifo size. * bmg160, bme680 - Typos * cio-dac - Switch to iomap rather than direct use of ioports * kxsd9 - Replace CONFIG_PM guards with new PM macros that let the compiler cleanly remove the unused code and structures when !CONFIG_PM * lsm6dsx - Use new pm_sleep_ptr() and EXPORT_SIMPLE_DEV_PM_OPS(). Then move to Namespace. * meson_saradc - general cleanup. - Avoid attaching resources to iio_dev->dev - Use same struct device for all error messages - Convert to dev_err_probe() and use local struct device *dev to reduce code complexity. - Use devm_clk_get_optional() instead of hand rolling. - Use regmap_read_poll_timeout() instead of hand rolling. * mma7660 - Drop ACPI_PTR() use that is unhelpful. * mpu3050 - Stop exporting symbols not used outside of module - Switch to new DEFINE_RUNTIME_DEV_PM_OPS() macro and move to Namespace. * ping - Typo fix * qcom-spmi-rradc - Typo fix * sc27xx - Convert to generic struct u32_fract * srf08 - Drop a redundant check on !val * st_lsm6dsx - Limit the requested watermark to the hwfifo size. * stm32-adc - Use generic_handle_domain_irq() instead of opencoding. - Fix handling of ADC disable. * stm32-dac - Use str_enabled_disable() instead of open coding. * stx104 - Switch to iomap rather than direct use of ioports * tsc2046 - Drop explicit setting of INDIO_BUFFER_TRIGGERED as now done by the core. * tsl2563 - Replace flush_scheduled_work() with cancel_delayed_work_sync() - Replace cancel_delayed_work() with cancel_delayed_work_sync() * vl53l0x - Make the VDD regulator optional by allowing a dummy regulator. * tag 'iio-for-5.20a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (244 commits) iio: adc: xilinx-xadc: Drop duplicate NULL check in xadc_parse_dt() iio: adc: xilinx-xadc: Make use of device properties iio: light: cm32181: Add PM support iio: adc: ad778-1: do not explicity set INDIO_BUFFER_TRIGGERED mode iio: adc: ti-tsc2046: do not explicity set INDIO_BUFFER_TRIGGERED mode iio: adc: stm32-adc: disable adc before calibration iio: adc: stm32-adc: make safe adc disable iio: dac: ad5380: align '*' each line and drop unneeded blank line iio: adc: qcom-spmi-rradc: Fix spelling mistake "coherrency" -> "coherency" iio: Don't use bare "unsigned" dt-bindings: iio: dac: mcp4922: expand for mcp4921 support iio: dac: mcp4922: add support to mcp4921 iio: chemical: sps30: Move symbol exports into IIO_SPS30 namespace iio: pressure: bmp280: Move symbol exports to IIO_BMP280 namespace iio: imu: bmi160: Move exported symbols to IIO_BMI160 namespace iio: adc: stm32-adc: Use generic_handle_domain_irq() proximity: vl53l0x: Make VDD regulator actually optional MAINTAINERS: add include/dt-bindings/iio to IIO SUBSYSTEM AND DRIVERS dt-bindings: iio/accel: Fix adi,adxl345/6 example I2C address iio: gyro: bmg160: Fix typo in comment ...

2022-04-28iio: imu: adis16480: Improve getting the optional clocksAndy Shevchenko1-16/+10
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.

2022-04-10iio: core: Simplify the registration of kfifo buffersMiquel Raynal3-3/+0
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.
