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.
