iio: core: Simplify the registration of kfifo buffers
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.

First set of new device support, fixes, cleanups and features for IIO in 5.18
This cycle we had quite a few series that applied similar changes to lots of drivers. To keep this description manageable I have called those out in their own section rather than per driver. Particularly pleased to see the long running AFE precision series going in this cycle. Series includes some late breaking fixes. New device support * adi,ada4250 amplifier - New driver and dt bindings for this programmable gain amplifier. * adi,admv1014 microwave down-converter - New driver, dt bindings and some device specific ABI that may be generalized as more drivers for devices similar to this are added. * adi,admv4420 K Band down-converter. - New driver and dt bindings. * adi,adxl367 accelerometer driver. - New driver, dt-bindings + some new IIO ABI definitions to support reference magnitude events where an estimate of the acceleration due to gravity has been removed. - A few fixes as follow up patches. * adi,ltc2688 DAC with toggle and dither modes. - New driver and bindings. Includes some new driver specific (for now) ABI for handling toggle mode and the addition of a dither waveform to the DAC output. * AFE (analog front end) add support for additional types of analog device in front of an ADC. - RTD temperature sensors with dt bindings. - Temperature transducers wit dt bindings. - Related cleanup and features listed in other sections below. * maxim,ds3502 potentiometer. - Add support to ds1803 driver which required significant rework. * mediatek,mt2701-auxadc driver - Add mediatek,mt8186-auxadc - id table and chip specific info only. * semtech,sx9324, semtech,ax9360 - Substantial refactoring of sx9310 to extract core logic for reuse into a separate module - New driver using this supporting sx9324 proximity sensors. - New driver using this supporting sx9360 proximity sensors. * silan,sc7a20 - Compatible with the st,lis2dh (or nearly anyway) so add ID and chip specific info to enable support. Also silan vendor ID added for dt-bindings. Staging graduation * adi,ad7280a monitoring ADC for stacked lithium-ion batteries in electric cars and similar. - Substantial rework of driver required to bring inline with current IIO best practice. An unusual device in IIO so some interesting features we may see more of in future. Multiple driver/core cleanup - Use sysfs_emit() in simple locations where there is no path to change to various core created attributes. - Trivial white space fixes around inconsistency between space after { and before } in id tables. - Introduce new handling for fractional types to avoid repeated similar implementations. Use this in 3 drivers. Note this is also targeted at future use in the AFE driver and was motivated by discussions around the precision related work on that driver. - of related header cleanups - drop of*.h and add mod_devicetable.h as appropriate. - Move a number of symbol exports into IIO_* namespaces. Two categories, 1) Library used by multiple drivers e.g. st_sensors 2) Core driver module exporting functions used by bus specific modules. A few related cleanups in this set. - Switch from CONFIG_PM_* guards to new DEFINE_SIMPLE_DEV_PM_OPS() and similar to simplify drivers and take advantage of these new macros allowing the compiler to do the job or removing unused code without the need for __maybe_unused markings. Conversion of other drivers to these new macros ongoing. Features * adi,adf4350 - Switch from of specific to generic device properties enabling use with other firmware types. * adi,adx345 - Switch from of specific to generic device properties. - Add ACPI ID ADS0345 - Related driver cleanup. * adi,hmc425a - Switch from of specific to generic device properties. * afe analog rescaler driver - Wider range of types supported for scale. - Support offset. - Kunit tests. * atlas,ezo-sensor - Convert from of to device properties. * fsl,mma8452 - Support mount matrix. * infineon,dps310: - Add ACPI ID IFX3100. * invensense,mpu6050 - Convert to generic device properties. * maxim,ds1803 - Add out_raw_available before supporting more devices. - Convert from of specific to device properties. * samsung,ssp_sensors - Convert from of specific to device properties. * st,stm32-timer trigger - Convert from of specific to device properties. * ti,hdc101x - Add ACPI ID TXNW1010. * ti,tsc2046: - Add read_raw support to enable use of iio_hwmon and similar.

First set of IIO new device and feature support for the 5.16 cycle
Counter subsystem changes now sent separately. This has been a busy cycle, so lots here and a few more stragglers to come next week. Big new feature in this cycle is probably output buffer support. This has been in the works for a very long time so it's great to see Mihail pick up the challenge and build upon his predecessors work to finally bring this feature to mainline. New device support ------------------ * adi,adxl313 - New driver and dt bindings for this low power accelerometer. * adi,adxl355 - New driver and dt bindings for this accelerometer. - Later series adds buffer support. * asahi-kasei,ak8975 - Minor additions to driver to support ak09916 * aspeed,aspeed-adc - Substantial rework plus feature additions to add support for the ast2600 including a new dt bindings doc. * atmel,at91_sama5d2 - Rework and support introduced for the sama7g5 parts. * maxim,max31865 - New driver and bindings for this RTD temperature sensor chip. * nxp,imx8qxp - New driver and bindings for the ADC found on the i.MX 8QuadXPlus Soc. * senseair,sunrise - New driver and bindings for this family of carbon dioxide gas sensors. * sensiron,scd4x - New driver and bindings for this carbon dioxide gas sensor. New features ------------ * Output buffer support. Works in a similar fashion to input buffers, but in this case userspace pushes data into the kfifo which is then drained to the device when a trigger occurs. Support added to the ad5766 DAC driver. * Core, devm_iio_map_array_register() to avoid need for devm_add_action_or_reset() based cleanup in fully managed allocation drivers. * Core iio_push_to_buffers_with_ts_unaligned() function to safely handle a few drivers where it really hard to ensure the correct data alignment in an iio_push_to_buffers_with_timestamp() call. Note this uses a bounce buffer so should be avoided whenever possible. Used in the ti,adc108s102, invense,mpu3050 and adi,adis16400. This closes the last known set of drivers with alignment issues at this interface. * maxim,max1027 - Substantial rework to this driver main target of which was supporting use of other triggers than it's own EOC interrupt. - Transfer optimization. * nxp,fxls8962af - Threshold even support including using it as a wakeup source. Cleanups, minor fixes etc ------------------------- Chances of a common type to multiple drivers: * devm_ conversion and drop of .remove() callbacks in: - adi,ad5064 - adi,ad7291 - adi,ad7303 - adi,ad7746 - adi,ad9832 - adi,adis16080 - dialog,da9150-gpadc - intel,mrfld_adc - marvell,berlin2 - maxim,max1363 - maxim,max44000 - nuvoton,nau7802 - st_sensors (includes a lot of rework!) - ti,ads8344 - ti,lp8788 * devm_platform_ioremap_resource() used to reduce boilerplate - cirrus,ep93xx - rockchip,saradc - stm,stm32-dac * Use dev_err_probe() in more places to both not print on deferred probe and ensure a reason for the deferral is available for debug purposes. - adi,ad8801 - capella,cm36651 - linear,ltc1660 - maxim,ds4424 - maxim,max5821 - microchip,mcp4922 - nxp,lpc18xx - onnn,noa1305 - st,lsm9ds0 - st,st_sensors - st,stm32-dac - ti,afe4403 - ti,afe4404 - ti,dac7311 * Drop error returns in SPI and I2C remove() functions as they are ignored and long term plan is to change these all over to returning void. In some cases these patches just make it 'obvious' they always return 0 where it was the case before but not easy to tell. - adi,ad5380 - adi,ad5446 - adi,ad5686 - adi,ad5592r - bosch,bma400 - bosch,bmc150 - fsl,mma7455 - honeywell,hmc5843 - kionix,kxsd9 - maxim,max5487 - meas,ms5611 - ti,afe4403 Driver specific changes * adi,ad5770r - Bring driver inline with documented bindings. * adi,ad7746 - Trivial style fix * adi,ad7949 - Express some magic values as the underlying parts via new #defines. - Make it work with SPI controllers that don't support 14 or 16 bit messages - Support selection of voltage reference from dt including expanding the dt-bindings to cover this new functionality. * adi,ad799x - Implement selection of external reference voltage on AD7991, AD7995 and AD7999. - Add missing dt-bindings doc for devices supported by this driver. * adi,adislib - Move interrupt startup to better location in startup flow. - Handle devices that cannot mask/unmask the drdy pin and must instead mask at the interrupt controller. Applies to the adis16460 and adis16475 from which we then drop equivalent code. * adi,ltc2983 - Add support for optional reset pin. - Fail to probe if no channels specified in dt binding. * asahi-kasei,ak8975 - dt-binding additions of missing vid-supply regulator. * aspeed,aspeed-adc - Typo fix. * fsl,mma7660 - Mark acpi_device_id table __maybe_unused to avoid build warning. * fsl,imx25-gcq - Avoid initializing regulators that aren't used. * invensense,mpu3050 - Drop a dead protection against a clash with the old input driver. * invensense,mpu6050 - Rework code to not use strcpy() and hence avoid possibility of wrong sized buffers. Note this wasn't a bug, but the new code is a lot more readable. - Mark acpi_device_id table __maybe_unused to avoid build warning. * kionix,kxcjk1013 - dt-binding addition to note it supports interrupts. * marvell,berlin2-adc - Enable COMPILE_TEST building. * maxim,max1027 - Avoid returning success in an error path. * nxp,imx8qxp - Fix warning when runtime pm not enabled via __maybe_unused. * ricoh,rn5t618 - Use the new devm_iio_map_array_register() instead of open coding the same. * samsung,exynos_adc - Improve kconfig help text. * st,lsm6dsx - Move max_fifo_size into the fifo_ops structure where the other configuration parameters are found. * st,st_sensors: - Reorder to ensure we turn the power off after removing userspace interfaces. * senseair,sunrise - Add missing I2C dependency. * ti,twl6030 - Small code tidy up. -----BEGIN PGP SIGNATURE----- iQJFBAABCAAvFiEEbilms4eEBlKRJoGxVIU0mcT0FogFAmFudVERHGppYzIzQGtl cm5lbC5vcmcACgkQVIU0mcT0Foiepg//R5DRm1gMFGP/dl2P8u6KD2oXNmbqc3J0 +EPRTkyTyawQzc21wdxUh3oObgxmDS6P7Cr17z9viGse2PsUjza4Sptic3Zqi3Kv FzeXZaP0GY9nC+hAyz+dSkMKNw19mkCYYEIWhDwYFpXMiOV8QlT+6pFgOiffofeR GYMUoV2XeuxR6OH0zMOuYKTzjOCYC+VJTP4BfeUetpRZQyllgFOA+5KX4ZWTiJMV eGCaq3Hhn6IQa7ATgYUBYJyMkAXQDrKDaMxiaCIuh/k3bgjAkfhkV48mu2cHTsX9 v0q21JkgmBenwNP/OQ6mxmWR9SFY4eB22Ptkd1foTPjAsqoST7qmqEBhhLrRb/fB HkL0I7M4tWDqSTJKgdn+UHYrKFW9oBHIt5SK1tCS+zTYIn1wEmkY/w/9MuZllBFO VKu5q2ypf/yGgCqPIZilK69mrZd7/72rE6tr3oefUF2iUVLdh9fI1TjGGyoT6GZ5 ZlEIfGHRpcRGHFiA4e+6tTx9VLr8m1B5YVvBWWPlruYe8ep7MmD3KjUcwINiRyNs 5rdBl2RI8VAUBbQ+60VWn03e/0kuRESpFC3Gf/ng+6hRSUbRFe4lZw60GbyFDXwV m1odTlkXA7l6oRG9f5COhE/oNO7dsfMO74W6+yzhWICnxjgJFosaaZTLw8F9QJdS m3z9tSU84js= =htmG -----END PGP SIGNATURE----- Merge tag 'iio-for-5.16a-split-take4' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: First set of IIO new device and feature support for the 5.16 cycle Counter subsystem changes now sent separately.

Support added to the ad5766 DAC driver. * Core, devm_iio_map_array_register() to avoid need for devm_add_action_or_reset() based cleanup in fully managed allocation drivers. * Core iio_push_to_buffers_with_ts_unaligned() function to safely handle a few drivers where it really hard to ensure the correct data alignment in an iio_push_to_buffers_with_timestamp() call. Note this uses a bounce buffer so should be avoided whenever possible. Used in the ti,adc108s102, invense,mpu3050 and adi,adis16400. This closes the last known set of drivers with alignment issues at this interface. * maxim,max1027 - Substantial rework to this driver main target of which was supporting use of other triggers than it's own EOC interrupt. - Transfer optimization. * nxp,fxls8962af - Threshold even support including using it as a wakeup source. Cleanups, minor fixes etc ------------------------- Chances of a common type to multiple drivers: * devm_ conversion and drop of .remove() callbacks in: - adi,ad5064 - adi,ad7291 - adi,ad7303 - adi,ad7746 - adi,ad9832 - adi,adis16080 - dialog,da9150-gpadc - intel,mrfld_adc - marvell,berlin2 - maxim,max1363 - maxim,max44000 - nuvoton,nau7802 - st_sensors (includes a lot of rework!) - ti,ads8344 - ti,lp8788 * devm_platform_ioremap_resource() used to reduce boilerplate - cirrus,ep93xx - rockchip,saradc - stm,stm32-dac * Use dev_err_probe() in more places to both not print on deferred probe and ensure a reason for the deferral is available for debug purposes. - adi,ad8801 - capella,cm36651 - linear,ltc1660 - maxim,ds4424 - maxim,max5821 - microchip,mcp4922 - nxp,lpc18xx - onnn,noa1305 - st,lsm9ds0 - st,st_sensors - st,stm32-dac - ti,afe4403 - ti,afe4404 - ti,dac7311 * Drop error returns in SPI and I2C remove() functions as they are ignored and long term plan is to change these all over to returning void. In some cases these patches just make it 'obvious' they always return 0 where it was the case before but not easy to tell. - adi,ad5380 - adi,ad5446 - adi,ad5686 - adi,ad5592r - bosch,bma400 - bosch,bmc150 - fsl,mma7455 - honeywell,hmc5843 - kionix,kxsd9 - maxim,max5487 - meas,ms5611 - ti,afe4403 Driver specific changes * adi,ad5770r - Bring driver inline with documented bindings. * adi,ad7746 - Trivial style fix * adi,ad7949 - Express some magic values as the underlying parts via new #defines. - Make it work with SPI controllers that don't support 14 or 16 bit messages - Support selection of voltage reference from dt including expanding the dt-bindings to cover this new functionality. * adi,ad799x - Implement selection of external reference voltage on AD7991, AD7995 and AD7999. - Add missing dt-bindings doc for devices supported by this driver. * adi,adislib - Move interrupt startup to better location in startup flow. - Handle devices that cannot mask/unmask the drdy pin and must instead mask at the interrupt controller. Applies to the adis16460 and adis16475 from which we then drop equivalent code. * adi,ltc2983 - Add support for optional reset pin. - Fail to probe if no channels specified in dt binding. * asahi-kasei,ak8975 - dt-binding additions of missing vid-supply regulator. * aspeed,aspeed-adc - Typo fix. * fsl,mma7660 - Mark acpi_device_id table __maybe_unused to avoid build warning. * fsl,imx25-gcq - Avoid initializing regulators that aren't used. * invensense,mpu3050 - Drop a dead protection against a clash with the old input driver. * invensense,mpu6050 - Rework code to not use strcpy() and hence avoid possibility of wrong sized buffers. Note this wasn't a bug, but the new code is a lot more readable. - Mark acpi_device_id table __maybe_unused to avoid build warning. * kionix,kxcjk1013 - dt-binding addition to note it supports interrupts. * marvell,berlin2-adc - Enable COMPILE_TEST building. * maxim,max1027 - Avoid returning success in an error path. * nxp,imx8qxp - Fix warning when runtime pm not enabled via __maybe_unused. * ricoh,rn5t618 - Use the new devm_iio_map_array_register() instead of open coding the same. * samsung,exynos_adc - Improve kconfig help text. * st,lsm6dsx - Move max_fifo_size into the fifo_ops structure where the other configuration parameters are found. * st,st_sensors: - Reorder to ensure we turn the power off after removing userspace interfaces. * senseair,sunrise - Add missing I2C dependency. * ti,twl6030 - Small code tidy up. * tag 'iio-for-5.16a-split-take4' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (148 commits) iio: imx8qxp-adc: mark PM functions as __maybe_unused iio: pressure: ms5611: Make ms5611_remove() return void iio: potentiometer: max5487: Don't return an error in .remove() iio: magn: hmc5843: Make hmc5843_common_remove() return void iio: health: afe4403: Don't return an error in .remove() iio: dac: ad5686: Make ad5686_remove() return void iio: dac: ad5592r: Make ad5592r_remove() return void iio: dac: ad5446: Make ad5446_remove() return void iio: dac: ad5380: Make ad5380_remove() return void iio: accel: mma7455: Make mma7455_core_remove() return void iio: accel: kxsd9: Make kxsd9_common_remove() return void iio: accel: bmi088: Make bmi088_accel_core_remove() return void iio: accel: bmc150: Make bmc150_accel_core_remove() return void iio: accel: bma400: Make bma400_remove() return void drivers:iio:dac:ad5766.c: Add trigger buffer iio: triggered-buffer: extend support to configure output buffers iio: kfifo-buffer: Add output buffer support iio: Add output buffer support iio: documentation: Document scd4x calibration use drivers: iio: chemical: Add support for Sensirion SCD4x CO2 sensor ... |

iio: accel: fxls8962af: add wake on event
This adds ways for the SoC to wake from accelerometer wake events. In the suspend function we skip disabling the sensor if wakeup-source and events are activated. If buffered reads are enabled they will be deactivated before suspend. As the onboard buffer is only holding up to 32 12-bit X/Y/Z data triplets.

iio: accel: fxls8962af: add hw buffered sampling
When buffered sampling is enabled, the accelerometer will dump data into the internal fifo and interrupt at watermark. Then the driver flushes all data to the iio buffer. As the accelerometer doesn't have internal timestamps, they are approximated between the current and last interrupt.
