| Subject: [PATCH] arm64: dts: ls104xa: set mask to drop TBU ID from StreamID
 | |
| 
 | |
| 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.
