Subject: [PATCH v16 18/20] dt-bindings: arm-smmu: Add compatible string for Adreno GPU SMMU
Date: Tue,  1 Sep 2020 09:46:35 -0700	[thread overview]
Message-ID: <20200901164707.2645413-19-robdclark@gmail.com> (raw)
In-Reply-To: <20200901164707.2645413-1-robdclark@gmail.com>

From: Jordan Crouse <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.
