Subject: [PATCH v2 1/3] dt-bindings: arm-smmu: Add binding doc for Qcom smmu-500
Date: Tue, 14 Aug 2018 15:57:38 +0530 [thread overview]
Message-ID: <20180814102740.30222-2-vivek.gautam@codeaurora.org> (raw)
In-Reply-To: <20180814102740.30222-1-vivek.gautam@codeaurora.org>
Qcom's implementation of arm,mmu-500 works well with current
arm-smmu driver implementation. Adding a soc specific compatible
along with arm,mmu-500 makes the bindings future safe.
