Subject: [PATCH 07/11] dts: arm64: layerscape: add dma-ranges property to qoric-mc node
Date: Tue, 24 Sep 2019 20:12:38 +0200	[thread overview]
Message-ID: <20190924181244.7159-8-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20190924181244.7159-1-nsaenzjulienne@suse.de>

qoriq-mc's dpmacs DMA configuration is inherited from their parent node,
which acts a bus in this regard. So far it maked all devices as
dma-coherent but no dma-ranges recommendation is made.

The truth is that the underlying interconnect has DMA constraints, so
add an empty dma-ranges in qoriq-mc's node in order for DT's DMA
configuration code to get the DMA constraints from it.
