From: Parker Newman <pnewman@xxxxxxxxxxxxxxx> Nvidia Tegra MGBE controllers require the iommu "Stream ID" (SID) to be written to a register for proper operation. The current driver is hard coded to mgbe0's SID, causing the other mgbe controller instances to not work. This patch enables the other mgbe controllers by reading the SID from the iommus property in the device tree using the existing tegra_dev_iommu_get_stream_id() function in linux/iommu.h.
