[PATCH v4 05/10] iio: buffer-dmaengine: Enable write support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Paul Cercueil <paul@xxxxxxxxxxxxxxx>

Use the iio_dma_buffer_write() and iio_dma_buffer_space_available()
functions provided by the buffer-dma core, to enable write support in
the buffer-dmaengine code.
