Subject: [PATCH v1 1/2] dmadev: add DMA operation structure
Date: Mon, 18 Sep 2023 18:02:26 +0530 [thread overview]
Message-ID: <20230918123227.1562074-1-amitprakashs@marvell.com> (raw)
For the event based DMA transfer, all the required parameters are to
be sent as part of a structure. This patch adds a structure
containing the parameters for event based DMA operation.
