Subject: [PATCH v2 09/19] dmaengine: dmatest: Use dmaengine_get_dma_device
Date: Tue, 17 Nov 2020 12:56:46 +0200 [thread overview]
Message-ID: <20201117105656.5236-10-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <20201117105656.5236-1-peter.ujfalusi@ti.com>
By using the dmaengine_get_dma_device() to get the device for
dma_api use, the dmatest can support per channel coherency if it is
supported by the DMA controller.
