-* QCOM IOMMU v1 Implementation
-
-Qualcomm "B" family devices which are not compatible with arm-smmu have
-a similar looking IOMMU but without access to the global register space,
-and optionally requiring additional configuration to route context irqs
-to non-secure vs secure interrupt line.
-
-** Required properties:
-
-- compatible : Should be one of:
-
- "qcom,msm8916-iommu"
-
- Followed by "qcom,msm-iommu-v1".
-
-- clock-names : Should be a pair of "iface" (required for IOMMUs
- register group access) and "bus" (required for
- the IOMMUs underlying bus access).
-
-- clocks : Phandles for respective clocks described by
- clock-names.
-
-- #address-cells : must be 1.
-
-- #size-cells : must be 1.
-
-- #iommu-cells : Must be 1. Index identifies the context-bank #.
-
-- ranges : Base address and size of the iommu context banks.
-
-- qcom,iommu-secure-id : secure-id.
-
-- List of sub-nodes, one per translation context bank. Each sub-node
- has the following required properties:
-
- - compatible : Should be one of:
- - "qcom,msm-iommu-v1-ns" : non-secure context bank
- - "qcom,msm-iommu-v1-sec" : secure context bank
- - reg : Base address and size of context bank within the iommu
- - interrupts : The context fault irq.
-
-** Optional properties:
-
-- reg : Base address and size of the SMMU local base, should
- be only specified if the iommu requires configuration
- for routing of context bank irq's to secure vs non-
- secure lines. (Ie. if the iommu contains secure
- context banks)
