WebSigned-off-by: Alexandru Ardelean Cc: Alexandru Ardelean Signed-off-by: Paul Cercueil --- WebIIO triggered buffer depends on IIO buffer which is missing from Kconfig file. This should go unnoticed most of the time because there's a chance something else has already enabled buffers. In some rare cases though one might experience kbuild warnings about unmet direct dependencies and build failures due to missing symbols.

WebUpdate the iio_dmaengine_buffer_submit() function to handle input buffers as well as output buffers. Signed-off-by: Paul Cercueil Reviewed-by: Alexandru Ardelean --- WebThe buffer-dma code was using two queues, incoming and outgoing, to manage the state of the blocks in use. While this totally works, it adds some complexity to the code, especially since the code only manages 2 blocks. easier to just check each block's state manually, and keep a counter for the next block to dequeue.
