From 6ac02df3fff71ddacc71e2ae79b73c16873b41c5 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Wed, 9 Mar 2022 19:35:27 -0600 Subject: dt-bindings: virtio,mmio: Allow setting devices 'dma-coherent' 'virtio,mmio' devices are always coherent within a guest. As Arm DTs are default non-coherent, the 'dma-coherent' property needs to be set on the virtio device to mark them as such. This aligns with the QEMU 'virt' machine DTB.
