git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC boardfile updates from Arnd Bergmann "Unused boardfile removal for 6.3 This is a follow-up to the deprecation of most of the old-style board files that was merged in linux-6.0, removing them for good. This branch is almost exclusively dead code removal based on those annotations. Some device driver removals went through separate subsystem trees, but the majority is in the same branch, in order to better handle dependencies between the patches and avoid breaking bisection. Unfortunately that leads to merge conflicts against other changes in the subsystem trees, but they should all be trivial to resolve by removing the files.

2023-01-21iio: light: vcnl4000: Make irq handling more genericMårten Lindahl
This driver supports 4 chips, by which only one (vcnl4010) handles interrupts and has support for triggered buffer. The setup of these functions is hardcoded for vcnl4010 inside the generic vcnl4000_probe, and thus ignores the chip specific configuration structure where all other chip specific functions are specified. This complicates adding interrupt handler and triggered buffer support to chips which may have support for it. Add members for irq threads and iio_buffer_setup_ops to the generic vcnl4000_chip_spec struct, so that instead of checking a chip specific boolean irq support, we check for a chip specific triggered buffer handler, and/or a chip specific irq thread handler.

2023-01-21iio: light: cm32181: Fix PM support on system with 2 I2C resourcesKai-Heng Feng
Commit c1e62062ff54 ("iio: light: cm32181: Handle CM3218 ACPI devices with 2 I2C resources") creates a second client for the actual I2C address, but the "struct device" passed to PM ops is the first I2C client that can't talk to the sensor. That means the I2C transfers in both suspend and resume routines can fail and blocking the whole suspend process. Instead of using the first client for I2C transfer, use the I2C client stored in the cm32181 private struct so the PM ops can get the correct I2C client to really talk to the sensor device.

2023-01-08iio: imu: st_lsm6dsx: fix build when CONFIG_IIO_TRIGGERED_BUFFER=mVladimir Oltean
The following kernel linkage error: st_lsm6dsx_core.o: in function `st_lsm6dsx_sw_buffers_setup': st_lsm6dsx_core.c:2578: undefined reference to `devm_iio_triggered_buffer_setup_ext' is caused by the fact that the object owning devm_iio_triggered_buffer_setup_ext() (drivers/iio/buffer/industrialio-triggered-buffer.o) is allowed to be built as module when its user (drivers/iio/imu/st_lsm6dsx/st_lsm6dsx_core.c) is built-in. The st_lsm6dsx driver already has a "select IIO_BUFFER", so add another select for IIO_TRIGGERED_BUFFER, to make that option follow what is set for the st_lsm6dsx driver. This is similar to what other iio drivers do.

2022-12-28iio: imu: fxos8700: fix ACCEL measurement range selectionCarlos Song
When device is in active mode, it fails to set an ACCEL full-scale range(2g/4g/8g) in FXOS8700_XYZ_DATA_CFG. This is not align with the datasheet, but it is a fxos8700 chip behavior. Keep the device in standby mode before setting ACCEL full-scale range into FXOS8700_XYZ_DATA_CFG in chip initialization phase and setting scale phase.

Apply a 2 bits signed right shift to the raw data from ACCEL output data register but keep that from MAGN sensor as the origin.
