From cab4ae7eb3045afe5874739653da7c5d686fd115 Mon Sep 17 00:00:00 2001 From: Laurentiu Tudor Date: Thu, 3 May 2018 18:05:43 +0300 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.
