Subject: [PATCH 2/2] arm64: dts: qcom: remove an unused property dma-ranges
Date: Tue, 13 Oct 2020 14:06:23 +0800	[thread overview]
Message-ID: <20201013060623.1711-3-thunder.leizhen@huawei.com> (raw)
In-Reply-To: <20201013060623.1711-1-thunder.leizhen@huawei.com>

ipq6018.dtsi is only included by ipq6018-cp01-c1.dts. I searched the
entire expanded ipq6018-cp01-c1.dts file, and only one dma-ranges was
defined. No conversion range is specified, so it cannot work properly.
I think this property "dma-ranges" is added by mistake, just remove it.
Otherwise, the following error will be reported when any YAML detection
is performed on arm64.

arch/arm64/boot/dts/qcom/ipq6018.dtsi:185.3-14: Warning \
(dma_ranges_format): /soc:dma-ranges: empty "dma-ranges" property but \
its #address-cells (1) differs from / (2)
arch/arm64/boot/dts/qcom/ipq6018.dtsi:185.3-14: Warning \
(dma_ranges_format): /soc:dma-ranges: empty "dma-ranges" property but \
its #size-cells (1) differs from / (2)
