2022-11-23iio: adc128s052: add proper .data members in adc128_of_match tableRasmus Villemoes
Prior to commit bd5d54e4d49d ("iio: adc128s052: add ACPI _HID AANT1280"), the driver unconditionally used spi_get_device_id() to get the index into the adc128_config array. However, with that commit, OF-based boards now incorrectly treat all supported sensors as if they are an adc128s052, because all the .data members of the adc128_of_match table are implicitly 0. Our board, which has an adc122s021, thus exposes 8 channels whereas it really only has two.

Add smart calibration support for STM32MP1. - STM32MP15x: both linear & offset calibration are supported - STM32MP13x: Only offset calibration is supported Linear calibration: Linear calibration is SoC dependent and does not change over time so it can be done only once. Linear calibration may have already been done in u-boot. Skip calibration execution if calibration data are already available. Save calibration factors in private data and restore them from private data on next ADC start. Offset calibration: This calibration may vary over time, depending on temperature or voltage. Run offset single-ended and differential calibration on each ADC start, as it is not time consuming. This calibration do not need to be saved.

2022-11-23iio: Don't silently expect attribute typesMatti Vaittinen
The iio_triggered_buffer_setup_ext() and the devm_iio_kfifo_buffer_setup_ext() were changed by commit 15097c7a1adc ("iio: buffer: wrap all buffer attributes into iio_dev_attr") to silently expect that all attributes given in buffer_attrs array are device-attributes. This expectation was not forced by the API - and some drivers did register attributes created by IIO_CONST_ATTR(). When using IIO_CONST_ATTRs the added attribute "wrapping" does not copy the pointer to stored string constant and when the sysfs file is read the kernel will access to invalid location. Change the function signatures to expect an array of iio_dev_attrs to avoid similar errors in the future. Merge conflict resolved whilst applying due to patch crossing with two new drivers (kx022a accelerometer and ad4130 ADC).
