Subject: [PATCH 08/11] dts: arm64: layerscape: add dma-ranges property to pcie nodes
Date: Tue, 24 Sep 2019 20:12:39 +0200 [thread overview]
Message-ID: <20190924181244.7159-9-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20190924181244.7159-1-nsaenzjulienne@suse.de>
The bus behind the board's PCIe core has DMA addressing limitations. Add
an empty 'dma-ranges' property on all PCIe bus descriptions to inform
the OF core that a translation is due further down the line.
