    arm64: tegra: Enable SMMU support for USB on Tegra194 · c667dcd4
    Thierry Reding authored
    As of commit c7289b1c ("arm64: tegra: Enable SMMU support on
    Tegra194"), SMMU support is enabled system-wide on Tegra194. However,
    there was a bit of overlap between the SMMU enablement and the USB
    support addition, so the USB device tree nodes are missing the iommus
    and interconnects properties. This in turn leads to SMMU faults for
    these devices, since by default the ARM SMMU will fault.
    
    Add the iommus and interconnects properties to the XUSB and XUDC device
    tree nodes to restore their functionality.
    
    Fixes: c7289b1c
