[PATCH v3 20/22] arm64: dts: ls104x: add iommu-map to pci controllers

From: laurentiu.tudor@nxp.com
Date: 2018-10-10 12:08:07
Also in: linux-arm-kernel, lkml, netdev
Subsystem: arm/freescale layerscape arm architecture, the rest · Maintainers: Frank Li, Linus Torvalds

From: Laurentiu Tudor <laurentiu.tudor@nxp.com>

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.
