Subject: [PATCH v18 3/4] dt-bindings: arm-smmu: Add compatible string for Adreno GPU SMMU
Date: Tue, 27 Oct 2020 16:34:07 -0600 [thread overview]
Message-ID: <20201027223408.469893-4-jcrouse@codeaurora.org> (raw)
In-Reply-To: <20201027223408.469893-1-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.
