From 8b9ef71400a382fc5ad5ef98e9a3d11d02be784e Mon Sep 17 00:00:00 2001 From: "Rob Herring (Arm)" Date: Mon, 13 Oct 2025 16:30:35 -0500 Subject: [PATCH] dt-bindings: dma: Convert apm,xgene-storm-dma to DT schema Convert APM X-Gene Storm DMA binding to DT schema format. It's a straight-forward conversion.
