iio: accel: fxls8962af: fixup buffer scan element type

2023-07-19T14:35:06Z

commit d1cfbd52ede5e5fabc09992894c5733b4057f159 upstream. Scan elements for x,y,z channels is little endian and requires no bit shifts. LE vs. BE is controlled in register SENS_CONFIG2 and bit LE_BE, default value is LE.

iio: accel: kx022a fix irq getting

2023-05-13T18:45:08Z

The fwnode_irq_get_byname() was returning 0 at device-tree mapping error. If this occurred, the KX022A driver did abort the probe but errorneously directly returned the return value from fwnode_irq_get_byname() from probe. In case of a device-tree mapping error this indicated success. The fwnode_irq_get_byname() has since been fixed to not return zero on error so the check for fwnode_irq_get_byname() can be relaxed to only treat negative values as errors. This will also do decent fix even when backported to branches where fwnode_irq_get_byname() can still return zero on error because KX022A probe should later fail at IRQ requesting and a prober error handling should follow. Relax the return value check for fwnode_irq_get_byname() to only treat negative values as errors.

iio: accel: st_accel: Fix invalid mount_matrix on devices without ACPI _ONT method

2023-05-13T16:54:57Z

When apply_acpi_orientation() fails, st_accel_common_probe() will fall back to iio_read_mount_matrix(), which checks for a mount-matrix device property and if that is not set falls back to the identity matrix. But when a sensor has no ACPI companion fwnode, or when the ACPI fwnode does not have a "_ONT" method apply_acpi_orientation() was returning 0, causing iio_read_mount_matrix() to never get called resulting in an invalid mount_matrix: [root@fedora ~]# cat /sys/bus/iio/devices/iio\:device0/mount_matrix (null), (null), (null); (null), (null), (null); (null), (null), (null) Fix this by making apply_acpi_orientation() always return an error when it did not set the mount_matrix.

Jonathan writes: 1st set of IIO new device support, features and cleanups for the 6.4 cycle. New device support * bosch,bmp280 - Add support for BMP580 - includes significant refactoring and general driver cleanup + support for non-volatile memory for trimming and config parameters. * rohm BU27034 - New driver for this 3 channel ambient light sensor. - New support library for devices where both integration time and amplifier gain are configurable. In these cases a scale change may require changing bother underlying values. This library module provides code to help with this. * st,accel - Add support for IIS328DQ (ID only as compatible wtih LIS331DL) * st,lsm6dsx - Add support for ASM330LHB automotive MEMS sensor. * ti,ads1100, ads1000 - New driver for these 16 bit ADCs. * ti,tmp117 - Add support for older tmp116 device. Includes some general driver cleanup. Staging driver drops * adi,ade7854 - Driver was a very long way from compliant with IIO infrastructure and ABI. If anyone wants a non staging version of this driver they are better off starting from scratch. Hence drop it and the associated meter.h header. Features * adi,ad7441r - Add DT binding to set sink current for digital input. * semtech,sx9324,9360 - Support older register mapping from firmware designed for windows. Core improvements. * Move iio_trigger_poll() docs to next to the implementation and add a note on expected caller context. * Rename iio_trigger_poll_chained() to iio_trigger_poll_nested() so as to use more standard / common terminology. * Improve main ABI docs references to offset and scale for raw values by making them consistent and clear. Cleanups and minor fixes: * adi,ad5592r - Add GPIO names - useful for debug. * adi,ad7441r - Fix current input, loop powered mode configuration setup. * adi,adis16475 - Fix wrong commented value for minimum advised lower rate. * adi,admv1013 - Use devm_clk_get_enabled() to reduce boilerplate. * adi,ads1210 - Fix wrong bits for writing config register (late fix and has been broken a long time so not rushed upstream) * amlogic,meson-saradc - Improve cleanup in error handling if BL30 handshake fails. * apex-embedded,stx104 - Migrate to regmap and use regmap_read_poll_timeout() to neatly handle retries. - Add local mutex to close various races. - Use define U16_MAX rather than value for limit. - Improve code readability with minor reorganization. * atmel,ad91-sama5d2 - Drop trivial dead code. * kionix,kx022a - Drop unused structure element. * linear,ltc2983 - Reorganize bindings doc to enable unevaluatedProperties to be set in one place for all child nodes. - Make binding for adi,custom-thermocouple accept signed values. * maxim,max44000 - Add OF Device matching (of_match_table was not correctly set). * maxim,max5522 - Missing static * measurement-computing,cio-dac - Fix wrong part name in comments. - Migrate to regmap. - Improve includes by replacing bitops.h with more direct bits.h * qcom,pm8xxx-xoadc - Remove a check that can never fail. * renesas,rcar-gyroadc - DT binding documentation improvements. - Tidy up an unused warning with __maybe_unused. * semtech,sx_common - Drop docs for a structure element that doesn't exist. * semtech,sx9500 - Drop ACPI_PTR() and of_match_ptr() protections that just complicate the code / block some firmware registration types that would otherwise work. * sensiron,sps30 - Comment formatting tidy up. * st,sensors - Drop duplicate text in DT binding. * st,stm32-adc - Add some missing static markings. * ti,ads1100 - Use correct return code in dev_err_probe() call. * x-powers,axp20x_adc - precursor series to simplify addition of AXP192. - General code cleanup / minor refactoring for better readabilty of code. - Switch from boolean value to mask for adc_en2 field to avoid hard coding a mask that will be different in AXP192 * tag 'iio-for-6.4a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (63 commits) MAINTAINERS: Add ROHM BU27034 iio: light: ROHM BU27034 Ambient Light Sensor dt-bindings: iio: light: Support ROHM BU27034 MAINTAINERS: Add IIO gain-time-scale helpers iio: light: Add gain-time-scale helpers doc: Make sysfs-bus-iio doc more exact iio: dac: set variable max5522_channels storage-class-specifier to static dt-bindings: iio: temperature: ltc2983: Make 'adi,custom-thermocouple' signed dt-bindings: iio: temperature: ltc2983: Fix child node unevaluated properties iio: addac: stx104: Use regmap_read_poll_timeout() for conversion poll iio: addac: stx104: Migrate to the regmap API iio: addac: stx104: Improve indentation in stx104_write_raw() iio: addac: stx104: Use define rather than hardcoded limit for write val iio: addac: stx104: Fix race condition when converting analog-to-digital iio: addac: stx104: Fix race condition for stx104_write_raw() dt-bindings: iio: st-sensors: Fix repeated text staging: iio: resolver: ads1210: fix config mode iio: adc: ti-ads1100: fix error code in probe() iio: accel: add support for IIS328DQ variant dt-bindings: iio: st-sensors: Add IIS328DQ accelerometer ...
