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
10 "rockchip,rk3288-vop";
11 "rockchip,rk3368-vop";
12 "rockchip,rk3366-vop";
13 "rockchip,rk3366-vop-lit";
14 "rockchip,rk3399-vop-big";
15 "rockchip,rk3399-vop-lit";
16 "rockchip,rk322x-vop";
17 "rockchip,rk3328-vop";
19 - reg: Address and length of the register set for the device.
20 - reg-names: The names of register regions. contain following regions:
21 - "regs" : (Required) Base address and size of the controllers.
22 - "cabc_lut" : (Optinal) cabc function lut table registers,
23 take care of this register's length, driver would use
24 register's length to decide cabc lut table size.
25 - "gamma_lut" : (Optinal) gamma function lut table registers,
26 take care of this register's length, driver would use
27 register's length to decide gamma table size.
29 - interrupts: should contain a list of all VOP IP block interrupts in the
30 order: VSYNC, LCD_SYSTEM. The interrupt specifier
31 format depends on the interrupt controller used.
33 - clocks: must include clock specifiers corresponding to entries in the
36 - clock-names: Must contain
37 aclk_vop: for ddr buffer transfer.
38 hclk_vop: for ahb bus to R/W the phy regs.
39 dclk_vop: pixel clock.
40 dclk_source: optinal, dclk sources from display plls.
42 - resets: Must contain an entry for each entry in reset-names.
43 See ../reset/reset.txt for details.
44 - reset-names: Must include the following entries:
49 - iommus: required a iommu node
51 - port: A port node with endpoint definitions as defined in
52 Documentation/devicetree/bindings/media/video-interfaces.txt.
