-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.
