Subject: [PATCH 8/9] arm64: tegra: Hook up VPR to host1x
Date: Tue, 2 Sep 2025 17:46:28 +0200 [thread overview]
Message-ID: <20250902154630.4032984-9-thierry.reding@gmail.com> (raw)
In-Reply-To: <20250902154630.4032984-1-thierry.reding@gmail.com>
From: Thierry Reding <treding@nvidia.com>
The host1x needs access to the VPR region, so make sure to reference it
via the memory-region property.
