Subject: [PATCH v10 07/13] dt-bindings: arm-smmu: Add compatible string for Adreno GPU SMMU
Date: Mon, 20 Jul 2020 09:40:41 -0600	[thread overview]
Message-ID: <20200720154047.3611092-8-jcrouse@codeaurora.org> (raw)
In-Reply-To: <20200720154047.3611092-1-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.
