Subject: [PATCH 4/7] dt-bindings: xilinx-dma: Extend 'xlnx,axistream-connected' property to MCDMA
Date: Thu, 12 Feb 2026 19:21:43 +0530 [thread overview]
Message-ID: <20260212135146.1185416-5-srinivas.neeli@amd.com> (raw)
In-Reply-To: <20260212135146.1185416-1-srinivas.neeli@amd.com>
Extend the xlnx,axistream-connected property for MCDMA IP. MCDMA also
supports AXI-Stream based designs, so the same property can be used to
enable stream-specific behavior and metadata handling.
