From 6ec29d4086ed8b951fa794ac6c0e7cd7ae3762d9 Mon Sep 17 00:00:00 2001 From: Inochi Amaoto Date: Mon, 3 Mar 2025 14:56:48 +0800 Subject: [PATCH] dt-bindings: dma: snps,dw-axi-dmac: Allow devices to be marked as noncoherent A RISC-V platform can have both DMA coherent/noncoherent devices. Since the RISC-V architecture is marked coherent, devices should be marked as noncoherent when coherent devices exist. Add dma-noncoherent property for snps,dw-axi-dmac device. It will be used on SG2044, and it has other coherent devices.
