Lars-Peter Clausen	9d452184fc	iio: buffer-dmaengine: Use dmaengine_terminate_sync() ... The DMAengine framework gained support for synchronized transfer termination. Use the new dmaengine_terminate_sync() function instead of dmaengine_terminate_all(), this avoids a potential race condition when disabling the buffer.

Lars-Peter Clausen	2d6ca60f32	iio: Add a DMAengine framework based buffer ... Add a generic fully device independent DMA buffer implementation that uses the DMAegnine framework to perform the DMA transfers. This can be used by converter drivers that whish to provide a DMA buffer for converters that are connected to a DMA core that implements the DMAengine API. Apart from allocating the buffer using iio_dmaengine_buffer_alloc() and freeing it using iio_dmaengine_buffer_free() no additional converter driver specific code is required when using this DMA buffer implementation.
