Subject: [PATCH v11 06/12] dt-bindings: arm-smmu: Add compatible string for Adreno GPU SMMU
Date: Mon, 3 Aug 2020 13:35:41 -0600 [thread overview]
Message-ID: <20200803193547.305660-7-jcrouse@codeaurora.org> (raw)
In-Reply-To: <20200803193547.305660-1-jcrouse@codeaurora.org>
Every Qcom Adreno GPU has an embedded SMMU for its own use. These
devices depend on unique features such as split pagetables,
different stall/halt requirements and other settings. Identify them
with a compatible string so that they can be identified in the
arm-smmu implementation specific code.
