Subject: [PATCH v3 18/22] arm64: dts: ls104xa: set mask to drop TBU ID from StreamID
Date: Wed, 10 Oct 2018 15:07:33 +0300 [thread overview]
Message-ID: <20181010120737.30300-16-laurentiu.tudor@nxp.com> (raw)
In-Reply-To: <20181010120737.30300-1-laurentiu.tudor@nxp.com>
From: Laurentiu Tudor <laurentiu.tudor@nxp.com>
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.
