Subject: [PATCH 3/4] dt-bindings: memory: tegra: Add Tegra264 stream IDs
Date: Tue, 8 Jul 2025 12:52:44 +0200 [thread overview]
Message-ID: <20250708105245.1516143-4-thierry.reding@gmail.com> (raw)
In-Reply-To: <20250708105245.1516143-1-thierry.reding@gmail.com>
From: Thierry Reding <treding@nvidia.com>
Add the stream IDs for various hardware blocks found on Tegra264. These
are allocated as blocks of 256 IDs and each block can be subdivided for
additional fine-grained isolation if needed.
