Subject: [PATCH 10/20] dt-bindings: arm-smmu: Add compatible string for Adreno GPU SMMU
Date: Mon, 17 Aug 2020 15:01:35 -0700 [thread overview]
Message-ID: <20200817220238.603465-11-robdclark@gmail.com> (raw)
In-Reply-To: <20200817220238.603465-1-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.
