Subject: ARM: dts: qcom: sdx55: Add Qcom SMMU-500 as the fallback for IOMMU node
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=89e99f0b031f273de31cb6bd3cdf076ec9f585d7;p=linux.git

ARM: dts: qcom: sdx55: Add Qcom SMMU-500 as the fallback for IOMMU node

commit af4ab377543853b690cc85b4c46cf976ab560dc2 upstream.

SDX55 uses the Qcom version of the SMMU-500 IP. So use "qcom,smmu-500"
compatible as the fallback to the SoC specific compatible.
