From 94afcfb819b3a07e55d463c29e2d594316f40b4a Mon Sep 17 00:00:00 2001 From: Radhey Shyam Pandey Date: Mon, 7 Aug 2023 11:21:40 +0530 Subject: dt-bindings: dmaengine: xilinx_dma:Add xlnx,axistream-connected property 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.
