Subject: [PATCH net-next v5 01/10] dt-bindings: dmaengine: xilinx_dma:Add xlnx,axistream-connected property
Date: Mon, 7 Aug 2023 11:21:40 +0530 [thread overview]
Message-ID: <1691387509-2113129-2-git-send-email-radhey.shyam.pandey@amd.com> (raw)
In-Reply-To: <1691387509-2113129-1-git-send-email-radhey.shyam.pandey@amd.com>
Add an optional AXI DMA property 'xlnx,axistream-connected'. This
can be specified to indicate that DMA is connected to a streaming IP
in the hardware design and dma driver needs to do some additional
handling i.e pass metadata and perform streaming IP specific
configuration.

Changes for v5:
- New patch in this series. Just a note that dmaengine series
was earlier sent as separate series[1] and now it's merged
with axiethernet series[2].
