2023-10-20Merge tag 'iio-for-6.7a' of ↵Greg Kroah-Hartman
https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: IIO: 1st set of new device support, features and cleanup for 6.7 Particularly great to see a resolver driver move out of staging via a massive set of changes. Only took 13 years :) One small patch added then reverted due to a report of test breakage (ashai-kasei,ak8975: Drop deprecated enums.) An immutable branch was used for some hid-senors changes in case there was a need to take them into the HID tree as well. New device support ----------------- adi,hmc425a - Add support for HMC540SLP3E broadband 4-bit digital attenuator. kionix,kx022a - Add support for the kx132-1211 accelerometer. Require significant driver rework to enable this including add a chip type specific structure to deal with the chip differences. - Add support for the kx132acr-lbz accelerometer (subset of the kx022a feature set). lltc,ltc2309 - New driver for this 8 channel ADC. microchip,mcp3911 - Add support for rest of mcp391x family of ADCs (there are various differences beyond simple channel count variation. Series includes some general driver cleanup. microchip,mcp3564 - New driver for MCP3461, MCP3462, MCP3464, MCP3541, MCP3562, MCP3564 and their R variants of 16/24bit ADCs. A few minor fixed followed. rohm,bu1390 - New driver for this pressure sensor. Staging graduation ------------------ adi,ad1210 (after 13 or so years :) - More or less a complete (step-wise) rewrite of this resolver driver to bring it up to date with modern IIO standards. The fault signal handling mapping to event channels was particularly complex and significant part of the changes. Features -------- iio-core - Add chromacity and color temperature channel types. adi,ad7192 - Oversampling ratio control (called fast settling in datasheet). adi,adis16475 - Add core support and then driver support for delta angle and delta velocity channels. These are intended for summation to establish angle and velocity changes over larger timescales. Fix was needed for alignment after the temperature channel. Further fix reduced set of devices for which the buffer support was applicable as seems burst reads don't cover these on all devices. hid-sensors-als - Chromacity and color temperatures support including in amd sfh. stx104 - Add support for counter subsystem to this multipurpose device. ti,twl6030 - Add missing device tree binding description. Clean up and minor fixes. ------------------------ treewide - Drop some unused declarations across IIO. - Make more use of device_get_match_data() instead of OF specific approaches. Similar cleanup to sets of drivers. - Stop platform remove callbacks returning anything by using the temporary remove_new() callback. - Use i2c_get_match_data() to cope nicely with all types of ID table entry. - Use device_get_match_data() for various platform device to cope with more types of firmware. - Convert from enum to pointer in ID tables allowing use of i2c_get_match_data(). - Fix sorting on some ID tables. - Include specific string helper headers rather than simply string_helpers.h docs - Better description of the ordering requirements etc for available_scan_masks. tools - Handle alignment of mixed sizes where the last element isn't the biggest correctly. Seems that doesn't happen often! adi,ad2s1210 - Lots of work from David Lechner on this driver including a few fixes that are going with the rework to avoid slowing that down. adi,ad4310 - Replace deprecated devm_clk_register() adi,ad74413r - Bring the channel function setting inline with the datasheet. adi,ad7192 - Change to FIELD_PREP(), FIELD_GET(). - Calculate f_order from the sinc filter and chop filter states. - Move more per chip config into data in struct ad7192_chip_info - Cleanup unused parameter in channel macros. adi,adf4350 - Make use of devm_* to simplify error handling for many of the setup calls in probe() / tear down in remove() and error paths. Some more work to be done on this one. - Use dev_err_probe() for errors in probe() callback. adi,adf4413 - Typo in function name prefix. adi,adxl345 - Add channel scale to the chip type specific structure and drop using a type field previously used for indirection. asahi,ak8985 - Fix a mismatch introduced when switching from enum->pointers in the match tables. amlogic,meson - Expand error logging during probe. invensense,mpu6050 - Support level-shifter control. Whilst no one is sure exactly what this is doing it is needed for some old boards. - Document mount-matrix dt-binding. mediatek,mt6577 - Use devm_clk_get_enabled() to replace open coded version and move everything over to being device managed. Drop now empty remove() callback. Fix follows to put the drvdata back. - Use dev_err_probe() for error reporting in probe() callback. memsic,mxc4005 - Add of_match_table. microchip,mcp4725 - Move various chip specific data from being looked up by chip ID to data in the chip type specific structure. silicon-labs,si7005 - Add of_match_table and entry in trivial-devices.yaml st,lsm6dsx - Add missing mount-matrix dt binding documentation. st,spear - Use devm_clk_get_enabled() and some other devm calls to move everything over to being device managed. Drop now empty remove() callback. - Use dev_err_probe() to better handled deferred probing and tidy up error reporting in probe() callback. st,stm32-adc - Add a bit of additional checking in probe() to protect against a NULL pointer (no known path to trigger it today). - Replace deprecated strncpy() ti,ads1015 - Allow for edge triggers. - Document interrupt in dt-bindings. * tag 'iio-for-6.7a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (201 commits) iio: Use device_get_match_data() iio: adc: MCP3564: fix warn: unsigned '__x' is never less than zero. dt-bindings: trivial-devices: add silabs,si7005 iio: si7005: Add device tree support drivers: imu: adis16475.c: Remove scan index from delta channels dt-bindings: iio: imu: st,lsm6dsx: add mount-matrix property iio: resolver: ad2s1210: remove of_match_ptr() iio: resolver: ad2s1210: remove DRV_NAME macro iio: resolver: ad2s1210: move out of staging staging: iio: resolver: ad2s1210: simplify code with guard(mutex) staging: iio: resolver: ad2s1210: clear faults after soft reset staging: iio: resolver: ad2s1210: refactor sample toggle staging: iio: resolver: ad2s1210: remove fault attribute staging: iio: resolver: ad2s1210: add label attribute support staging: iio: resolver: ad2s1210: add register/fault support summary staging: iio: resolver: ad2s1210: implement fault events iio: event: add optional event label support staging: iio: resolver: ad2s1210: rename DOS reset min/max attrs staging: iio: resolver: ad2s1210: convert DOS mismatch threshold to event attr staging: iio: resolver: ad2s1210: convert DOS overrange threshold to event attr ...

2023-09-23iio: proximity: srf04: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-07-23iio: adc: Explicitly include correct DT includesRob Herring
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2022-09-21iio: proximity: srf04: Use pm_ptr() to remove unused struct dev_pm_opsJonathan Cameron
If CONFIG_PM is not set, the pm_ptr() will ensure that the struct dev_pm_ops and callbacks are removed without the need for __maybe_unused markings. In this case we can't simply use DEFINE_RUNTIME_DEV_PM_OPS() because that would provide suspend and resume functions without the checks the driver is doing before calling runtime_pm functions (whether the necessary GPIO is provided). It may be possible to clean that up in future by moving the checks into the callbacks.

2022-08-16i2c: Make remove callback return voidUwe Kleine-König
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 ...
