changes in v2:
- rename "lcdc" to "vop"
- add vop reset
- add iommu node
- add port for display-subsystem

+device-tree bindings for rockchip soc display controller (vop)
+
+VOP (Visual Output Processor) is the Display Controller for the Rockchip
+series of SoCs which transfers the image data from a video memory
+buffer to an external LCD interface.
+
+Required properties:
+- compatible: value should be one of the following
+ "rockchip,rk3288-vop";
+
+- interrupts: should contain a list of all VOP IP block interrupts in the
+ order: VSYNC, LCD_SYSTEM. The interrupt specifier
+ format depends on the interrupt controller used.
+
+- clocks: must include clock specifiers corresponding to entries in the
+ clock-names property.
+
+- clock-names: Must contain
+ aclk_vop: for ddr buffer transfer.
+ hclk_vop: for ahb bus to R/W the phy regs.
+ dclk_vop: pixel clock.
+
+- resets: Must contain an entry for each entry in reset-names.
+ See ../reset/reset.txt for details.
+- reset-names: Must include the following entries:
+ - axi
+ - ahb
+ - dclk
+
+- iommus: required a iommu node
+
+- port: A port node with endpoint definitions as defined in
+ Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Example:
+SoC specific DT entry:
+ vopb: vopb@...30000 {
+ compatible = "rockchip,rk3288-vop";
+ reg = <0xff930000 0x19c>;
+ interrupts = <GIC_SPI 15 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&cru ACLK_VOP0>, <&cru DCLK_VOP0>, <&cru HCLK_VOP0>;
+ clock-names = "aclk_vop", "dclk_vop", "hclk_vop";
+ resets = <&cru SRST_LCDC1_AXI>, <&cru SRST_LCDC1_AHB>, <&cru SRST_LCDC1_DCLK>;
+ reset-names = "axi", "ahb", "dclk";
+ iommus = <&vopb_mmu>;
+ vopb_out: port {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ vopb_out_edp: endpoint@0 {
+ reg = <0>;
+ remote-endpoint=<&edp_in_vopb>;
+ };
+ vopb_out_hdmi: endpoint@1 {
+ reg = <1>;
+ remote-endpoint=<&hdmi_in_vopb>;
+ };
+ };
+ };
