Subject: [PATCH v3 03/11] dt-bindings: gpu: host1x: Document memory-regions for NVDEC
Date: Wed, 01 Jul 2026 18:08:14 +0200 [thread overview]
Message-ID: <20260701-tegra-vpr-v3-3-d80f7b871bb4@nvidia.com> (raw)
In-Reply-To: <20260701-tegra-vpr-v3-0-d80f7b871bb4@nvidia.com>
From: Thierry Reding <treding@nvidia.com>
The video protection region is a reserved memory region that can be used
for secure video playback. NVDEC can access this region to decode images
into securely.
