2022-08-19dt-bindings: iio: temperature: use spi-peripheral-props.yamlKrzysztof Kozlowski3-6/+10
Instead of listing directly properties typical for SPI peripherals, reference the spi-peripheral-props.yaml schema. This allows using all properties typical for SPI-connected devices, even these which device bindings author did not tried yet. Remove the spi-* properties which now come via spi-peripheral-props.yaml schema, except for the cases when device schema adds some constraints like maximum frequency. While changing additionalProperties->unevaluatedProperties, put it in typical place, just before example DTS.

2022-08-16iio: magnetometer: yas530: Add YAS537 variantJakob Hauser2-3/+423
Add support for the magnetometer Yamaha YAS537. The additions are based on comparison of Yamaha Android kernel drivers for YAS532 [1] and YAS537 [2]. In the Yamaha YAS537 Android driver, there is an overflow/underflow control implemented. For regular usage, this seems not necessary. A similar overflow/ underflow control of Yamaha YAS530/532 Android driver isn't integrated in the mainline driver. It is therefore skipped for YAS537 in the mainline too. Also in the Yamaha YAS537 Android driver, at the end of the reset_yas537() function, a measurement is saved in "last_after_rcoil". Later on, this is compared to current measurements. If the difference gets too big, a new reset is initialized. The difference in measurements needs to be quite big, it's hard to say if this is necessary for regular operation. Therefore this isn't integrated in the mainline driver either.

2022-08-16iio: magnetometer: yas530: Change data type of calibration coefficientsJakob Hauser1-2/+4
This is a preparation for adding YAS537 variant. YAS537 uses other data types on the calibration coefficients [1] than YAS530 [2] and YAS532 [3]. On YAS537, at least for a4 and a7 this could matter because 8-bit unsigned data from the register gets stored into a signed data type, therefore this should be 8-bit as well. For YAS530/532, on the other hand, it doesn't seem to matter. The size of a2-a9 and k is smaller than 8-bit at extraction, also the applied math is low. And Cx/Cy1/Cy2, now being defined as signed 16-bit, are extracted as unsigned 8-bit and undergo only minor math.

2022-08-16iio: magnetometer: yas530: Correct temperature handlingJakob Hauser1-23/+76
The raw temperature value is a number of counts from a certain starting point. The resolution of the temperature counts is different for the YAS variants. Temperature compensation for YAS532 version AC seems to be handled differently. It uses the deviation from 20 degree Celsius [1] whereas YAS530 and older versions of YAS532 apply solely the t value as a multiplier [2][3]. In funtion yas5xx_read_raw(), add case IIO_CHAN_INFO_PROCESSED. Remove scale of temperature as this isn't applied. Additionally correct sign of temperature channel in iio_chan_spec. It's already defined that way in the yas5xx_get_measure() function.

____cacheline_aligned is an insufficient guarantee for non-coherent DMA on platforms with 128 byte cachelines above L1. Switch to the updated IIO_DMA_MINALIGN definition. As the tx[] an rx[] buffers are only used in the same SPI exchanges, we should be safe with them on the same cacheline. Hence only mark the first one __aligned(IIO_DMA_MINALIGN).
