| Device Tree bindings for Arm Komeda display driver |
| |
| Required properties: |
| - compatible: Should be "arm,mali-d71" |
| - reg: Physical base address and length of the registers in the system |
| - interrupts: the interrupt line number of the device in the system |
| - clocks: A list of phandle + clock-specifier pairs, one for each entry |
| in 'clock-names' |
| - clock-names: A list of clock names. It should contain: |
| - "aclk": for the main processor clock |
| - #address-cells: Must be 1 |
| - #size-cells: Must be 0 |
| - iommus: configure the stream id to IOMMU, Must be configured if want to |
| enable iommu in display. for how to configure this node please reference |
| devicetree/bindings/iommu/arm,smmu-v3.txt, |
| devicetree/bindings/iommu/iommu.txt |
| |
| Required properties for sub-node: pipeline@nq |
| Each device contains one or two pipeline sub-nodes (at least one), each |
| pipeline node should provide properties: |
| - reg: Zero-indexed identifier for the pipeline |
| - clocks: A list of phandle + clock-specifier pairs, one for each entry |
| in 'clock-names' |
| - clock-names: should contain: |
| - "pxclk": pixel clock |
| |
| - port: each pipeline connect to an encoder input port. The connection is |
| modeled using the OF graph bindings specified in |
| Documentation/devicetree/bindings/graph.txt |
| |
| Optional properties: |
| - memory-region: phandle to a node describing memory (see |
| Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt) |
| to be used for the framebuffer; if not present, the framebuffer may |
| be located anywhere in memory. |
| |

| interrupts = <0 168 4>; |
| clocks = <&dpu_aclk>; |
| clock-names = "aclk"; |
| iommus = <&smmu 0>, <&smmu 1>, <&smmu 2>, <&smmu 3>, |
| <&smmu 4>, <&smmu 5>, <&smmu 6>, <&smmu 7>, |
| <&smmu 8>, <&smmu 9>; |

| reg = <0>; |
| |
| port { |

| }; |
| }; |
| }; |
| }; |
| ... |
