Subject: [PATCH] arm64: dts: ls1028a: fix dwc pci over smmu
|
|
|
|
In order for the dwc controller to work with SMMU it needs the
|
|
bootloader to fixup it's iommu-map property. In the current
|
|
implementation to bootloader will not perform the fixup if the
|
|
property is not already in the device tree with dummy fields.
|
|
Add it to fix DWC PCI over SMMU.
