[PATCH 5/7] arm64: dts: apple: t6030: Add NVMe device nodes
From: Janne Grunau
Date: Fri Sep 25 2026 - 05:50:33 EST
Apple silicon SoCs have a built-in NVMe host controller. Using it
requires device nodes for its IOMMU (SART), its mailbox and the ANS
coprocessor implementing the NVMe host controller.
