    iio: Add a DMAengine framework based buffer · 2d6ca60f
    Lars-Peter Clausen 提交于
    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.
