From: Laurentiu Tudor <laurentiu.tudor@xxxxxxx> The StreamID entering the SMMU is actually a concatenation of the SMMU TBU ID and the ICID configured in software. Since the TBU ID is internal to the SoC and since we want that the actual the ICID configured in software to enter the SMMU witout any additional set bits, mask out the TBU ID bits and leave only the relevant ICID bits to enter SMMU.
