Message-ID: <20250708105245.1516143-4-thierry.reding@gmail.com> Date: Tue, 8 Jul 2025 12:52:44 +0200 From: Thierry Reding <thierry.reding@...il.com> To: Thierry Reding <thierry.reding@...il.com>, Krzysztof Kozlowski <krzk@...nel.org> Cc: Rob Herring <robh@...nel.org>, Conor Dooley <conor+dt@...nel.org>, Jonathan Hunter <jonathanh@...dia.com>, linux-tegra@...r.kernel.org, devicetree@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 3/4] dt-bindings: memory: tegra: Add Tegra264 stream IDs From: Thierry Reding <treding@...dia.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.
