Subject: [PATCH v3 1/9] dt-bindings: host1x: Add memory-contexts property
Date: Fri, 18 Feb 2022 13:39:44 +0200	[thread overview]
Message-ID: <20220218113952.3077606-2-mperttunen@nvidia.com> (raw)
In-Reply-To: <20220218113952.3077606-1-mperttunen@nvidia.com>

Add schema information for the memory-contexts property used to
specify context stream IDs. This uses the standard iommu-map property
inside a child node.

Signed-off-by: Mikko Perttunen <mperttunen@nvidia.com>
