Add basic support for NXP FXLS8962AF/FXLS8964AF Automotive accelerometers. It will allow setting up scale/gain and reading x,y,z axis. Datasheet: https://www.nxp.com/docs/en/data-sheet/FXLS8962AF.pdf Datasheet: https://www.nxp.com/docs/en/data-sheet/FXLS8964AF.pdfSigned-off-by:

With CONFIG_ACPI=n and -Werror, 0-day reports: drivers/iio/chemical/bme680_i2c.c:46:36: error: 'bme680_acpi_match' defined but not used Apparently BME0680 is not a valid ACPI ID. Remove the ID. Note the driver will still work with ACPI bindings that use the PRP0001 mechanism as that uses the of_device_id table instead. Reported-by:

BME0680 is not an official ACPI ID, so let's remove it before someone starts using it. Note that ACPI can still be used with this driver via the PRP0001 method which will use the of_device_id table to match. Signed-off-by:

With CONFIG_ACPI=n, W=1 and -Werror, 0-day reports: drivers/iio/accel/stk8312.c:644:36: error: 'stk8312_acpi_id' defined but not used Apparently STK8312 is not a valid ACPI ID. Remove the ID table as this is the only entry. If ACPI support is desired an explicit of_device_id table should be added (rather than relying on the fallback to the existing ID table). Reported-by:

With CONFIG_ACPI=n and -Werror, 0-day reports: drivers/iio/humidity/am2315.c:259:36: error: 'am2315_acpi_id' defined but not used According to Andy Shevchenko, the ACPI ID used in this driver is fake and does not really exist. Remove it and with it ACPI support from the driver. Note that, if an explicit of_device_id table is added to the driver it could support the PRP0001 based ACPI approach. Reported-by:

We can utilize separate drivers for accelerometer and magnetometer, so here is the glue driver to enable LSM9DS0 IMU support. The idea was suggested by Crestez Dan Leonard in [1]. The proposed change was sent as RFC due to race condition concerns, which are indeed possible. In order to amend the initial change, I went further by providing a specific multi-instantiate probe driver that reuses existing accelerometer and magnetometer.

In case we would initialize two IIO devices from one physical device, we shouldn't have a clash on regulators. That's why move st_sensors_power_enable() call from core to bus drivers. Signed-off-by:

Provide default platform data for magnetometer in case it supports DRDY. One case is LSM9DS0 IMU, on which it is the case. Since accelerometer is using INT1, default magnetometer to INT2. While at it, update description of the drdy_int_pin field. Signed-off-by:

Continuing move to hide internal elements from drivers, move this structure element over. It's only accessed from iio core files so this one was straight forward and no accessor functions are needed. Signed-off-by:

indio_dev was both the macro input parameter and the field name in this macro. That causes trouble if the instance of struct iio_dev passed in is not called indio_dev. Whilst a fix of sorts, no need to backport as it seems we never hit this previously due to some very consistent naming in IIO. Signed-off-by:

Continuing from Alexandru Ardelean's introduction of the split between driver modifiable fields and those that should only be set by the core. This could have been done in two steps to make the actual move after introducing iio_device_id() but there seemed limited point to that given how mechanical the majority of the patch is. Includes fixup from Alex for missing mxs-lradc-adc conversion. Signed-off-by:

Basically the TI TSC2046 touchscreen controller is 8 channel ADC optimized for the touchscreen use case. By implementing it as an IIO ADC device, we can make use of resistive-adc-touch and iio-hwmon drivers. Polled readings are currently not implemented to keep this patch small, so iio-hwmon will not work out of the box for now. So far, this driver was tested with a custom version of resistive-adc-touch driver, since it needs to be extended to make use of Z1 and Z2 channels. The X/Y are working without additional changes.

Commit 63cd35f3 ("iio: Documentation: update definitions for bufferY and scan_elements") updated iio documentation in order to point to the newly per-buffer API, as it is now possible to support multi buffers. While the previous ABI will be kept forever, the best is for applications to use the 5.11+ ABI. So, move the legacy one ABI/obsolete. This fixes an issue with scripts/get_abi.pl, that doesn't accept two different Kernel version support for the same API set.

The adf4371 has channels that are very closely coupled, so additional documentation is needed to express these constraints. Unfortunately having the same sysfs filename in multiple documentation does not work well when generating automated documentation. To avoid this issue, we add a new device specific description to the main docs and remove the one in the device specific file.
