Subject: [PATCH v2 09/10] arm64: tegra: Hook up VPR to host1x
Date: Thu, 22 Jan 2026 17:10:08 +0100 [thread overview]
Message-ID: <20260122161009.3865888-10-thierry.reding@kernel.org> (raw)
In-Reply-To: <20260122161009.3865888-1-thierry.reding@kernel.org>
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.
Signed-off-by: Thierry Reding <treding@nvidia.com>
