Subject: [PATCH v8 3/7] dt-bindings: arm-smmu: Add compatible string for Adreno GPU SMMU
Date: Thu, 11 Jun 2020 16:21:24 -0600 [thread overview]
Message-ID: <20200611222128.28826-4-jcrouse@codeaurora.org> (raw)
In-Reply-To: <20200611222128.28826-1-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.
