Subject: [PATCH v4 05/10] iio: buffer-dmaengine: Enable write support
Date: Fri, 19 Apr 2024 10:25:38 +0200 [thread overview]
Message-ID: <20240419-iio-backend-axi-dac-v4-5-5ca45b4de294@analog.com> (raw)
In-Reply-To: <20240419-iio-backend-axi-dac-v4-0-5ca45b4de294@analog.com>
From: Paul Cercueil <paul@crapouillou.net>
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.
