From 317d4e577ede33f226d24bd12a8edbaafee22e57 Mon Sep 17 00:00:00 2001

Subject: [PATCH] arm64: dts: ls104x: add iommu-map to pci controllers
The pci controllers are also behind the smmu so add the iommu-map
property to reflect this. The bootloader needs to patch the stream id
ranges to some sane values.
