From 74eac50391ce42c5d0038d6f0e580576e53aec4e Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Mon, 5 Dec 2022 10:45:30 +0100 Subject: [PATCH] dt-bindings: PCI: qcom: Allow 'dma-coherent' property Devices on some PCIe buses may be cache coherent and must be marked as such in the devicetree to avoid data corruption. This is specifically needed on recent Qualcomm platforms like SC8280XP.
