Subject: [PATCH v2 3/4] dt: bindings: add bindings for wifi iommu node
Date: Mon, 1 Oct 2018 16:56:35 +0530 [thread overview]
Message-ID: <20181001112636.31715-4-govinds@codeaurora.org> (raw)
In-Reply-To: <20181001112636.31715-1-govinds@codeaurora.org>
WCN3990 wifi module can optionally make use of the IOMMU.
Add binding documentation for phandle to the IOMMU and
the stream id of wifi iommu block.
