[PATCH v4 1/2] dt-bindings: arm-smmu: Add binding doc for Qcom smmu-500
From: Vivek Gautam
Date: Thu Oct 11 2018 - 05:49:50 EST
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.
