1 device-tree bindings for rockchip soc display controller (vop)
3 VOP (Visual Output Processor) is the Display Controller for the Rockchip
4 series of SoCs which transfers the image data from a video memory
5 buffer to an external LCD interface.
8 - compatible: value should be one of the following
11 - interrupts: should contain a list of all VOP IP block interrupts in the
12 order: VSYNC, LCD_SYSTEM. The interrupt specifier
13 format depends on the interrupt controller used.
15 - clocks: must include clock specifiers corresponding to entries in the
18 - clock-names: Must contain
19 aclk_vop: for ddr buffer transfer.
20 hclk_vop: for ahb bus to R/W the phy regs.
21 dclk_vop: pixel clock.
23 - resets: Must contain an entry for each entry in reset-names.
24 See ../reset/reset.txt for details.
25 - reset-names: Must include the following entries:
30 - iommus: required a iommu node
32 - port: A port node with endpoint definitions as defined in
33 Documentation/devicetree/bindings/media/video-interfaces.txt.
