Subject: [PATCH v1 07/27] dt-bindings: gpu: mali-valhall-csf: Add Mali Gen5 AM compatible
Date: Tue, 22 Sep 2026 21:45:01 +0100 [thread overview]
Message-ID: <20260922204535.2850094-8-karunika.choo@arm.com> (raw)
In-Reply-To: <20260922204535.2850094-1-karunika.choo@arm.com>
Add the generic "arm,mali-gen5-am" compatible for Mali Gen5 AM GPU
integrations.
Mali Gen5 AM systems use the external AM_GOVERNOR block for frequency
scaling, so OPP, cooling and local GPU supply properties are not valid
for this compatible.
Add a matching example node.
