Subject: [PATCH v3 03/17] dt-bindings: qcom-bam: Add 'iommus' to required properties
Date:   Wed, 19 May 2021 20:06:46 +0530

Add the missing required property - 'iommus' to the
device-tree binding documentation for qcom-bam DMA IP.

This property describes the phandle(s) to apps_smmu node with sid mask.
