* iio: dac: ad5766: Fix alignment for DMA safetyJonathan Cameron2022-06-141-1/+1
| | | | | | | | | | | ____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.

* iio: expose shared parameter in IIO_ENUM_AVAILABLEAntoniu Miclaus2021-11-271-11/+2
| | | | | | | | | | | | | | | | | | | | | | | The shared parameter should be configurable based on its usage, and not constrained to IIO_SHARED_BY_TYPE. This patch aims to improve the flexibility in using the IIO_ENUM_AVAILABLE define and avoid redefining custom iio enums that expose the shared parameter. An example is the ad5766.c driver where IIO_ENUM_AVAILABLE_SHARED was defined in order to achieve `shared` parameter customization. The current state of the IIO_ENUM_AVAILABLE implementation will imply similar redefinitions each time a driver will require access to the `shared` parameter. An example would be admv1013 driver which will require custom device attribute for the frequency translation modes: Quadrature I/Q mode and Intermediate Frequency mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | In the documentation the name for the property is output-range-microvolts which is a standard name, therefore this name must be used.
