Subject: [PATCH 2/7] dt-bindings: dmaengine: xilinx_dma: Move xlnx,irq-delay to common AXI DMA and MCDMA section
Date: Thu, 12 Feb 2026 19:21:41 +0530 [thread overview]
Message-ID: <20260212135146.1185416-3-srinivas.neeli@amd.com> (raw)
In-Reply-To: <20260212135146.1185416-1-srinivas.neeli@amd.com>
xlnx,irq-delay property is applicable to both AXI DMA and MCDMA
designs. Move it from "Optional properties for AXI DMA" to "Optional
properties for AXI DMA and MCDMA" section to correctly reflect its usage.
