-* QCOM IOMMU
-
-The MSM IOMMU is an implementation compatible with the ARM VMSA short
-descriptor page tables. It provides address translation for bus masters outside
-of the CPU, each connected to the IOMMU through a port called micro-TLB.
-
-Required Properties:
-
- - compatible: Must contain "qcom,apq8064-iommu".
- - reg: Base address and size of the IOMMU registers.
- - interrupts: Specifiers for the MMU fault interrupts. For instances that
-support secure mode two interrupts must be specified, for non-secure and
-secure mode, in that order. For instances that don't support secure mode a
-single interrupt must be specified.
- - #iommu-cells: The number of cells needed to specify the stream id. This
- is always 1.
- - qcom,ncb:The total number of context banks in the IOMMU.
- - clocks : List of clocks to be used during SMMU register access. See
- Documentation/devicetree/bindings/clock/clock-bindings.txt
- for information about the format. For each clock specified
- here, there must be a corresponding entry in clock-names
- (see below).
-
- - clock-names: List of clock names corresponding to the clocks
specified in
- the "clocks" property (above).
- Should be "smmu_pclk" for specifying the interface clock
- required for iommu's register accesses.
- Should be "smmu_clk" for specifying the functional clock
- required by iommu for bus accesses.
-
-Each bus master connected to an IOMMU must reference the IOMMU in its device
-node with the following property:
-
- - iommus: A reference to the IOMMU in multiple cells. The first cell is a
- phandle to the IOMMU and the second cell is the stream id.
- A single master device can be connected to more than one iommu
- and multiple contexts in each of the iommu. So multiple entries
- are required to list all the iommus and the stream ids that the
- master is connected to.
-
-Example: mdp iommu and its bus master
-
-mdp_port0: iommu@750 {
- compatible = "qcom,apq8064-iommu";
- #iommu-cells = <1>;
- clock-names =
- "smmu_pclk",
- "smmu_clk";
- clocks =
- < SMMU_AHB_CLK>,
- < MDP_AXI_CLK>;
- reg = <0x0750 0x10>;
- interrupts =
- ,
- ;
- qcom,ncb = <2>;
- };
-
- mdp: qcom,mdp@510 {
- compatible = "qcom,mdp";
- ...
- iommus = <_port0 0
- _port0 2>;
- };
