+Device-Tree bindings for Samsung Exynos SoC display controller (DECON)
+
+DECON (Display and Enhancement Controller) is the Display Controller for the
+Exynos series of SoCs which transfers the image data from a video memory
+buffer to an external LCD interface.
+
+Required properties:
+- compatible: value should be "samsung,exynos5433-decon";
+- reg: physical base address and length of the DECON registers set.
+- interrupts: should contain a list of all DECON IP block interrupts in the
+ order: VSYNC, LCD_SYSTEM. The interrupt specifier format
+ depends on the interrupt controller used.
+- interrupt-names: should contain the interrupt names: "vsync", "lcd_sys"
+ in the same order as they were listed in the interrupts
+ property.
+- clocks: must include clock specifiers corresponding to entries in the
+ clock-names property.
+- clock-names: list of clock names sorted in the same order as the clocks
+ property. Must contain "aclk_decon", "aclk_smmu_decon0x",
+ "aclk_xiu_decon0x", "pclk_smmu_decon0x", clk_decon_vclk",
+ "sclk_decon_eclk"
+- ports: contains a port which is connected to mic node. address-cells and
+ size-cells must 1 and 0, respectively.
+- port: contains an endpoint node which is connected to the endpoint in the mic
+ node. The reg value muset be 0.
+- i80-if-timings: specify whether the panel which is connected to decon uses
+ i80 lcd interface or mipi video interface. This node contains
+ no timing information as that of fimd does. Because there is
+ no register in decon to specify i80 interface timing value,
+ it is not needed, but make it remain to use same kind of node
+ in fimd and exynos7 decon.
+
+Example:
+SoC specific DT entry:
+decon: decon@13800000 {
+ compatible = "samsung,exynos5433-decon";
+ reg = <0x13800000 0x2104>;
+ clocks = <&cmu_disp CLK_ACLK_DECON>, <&cmu_disp CLK_ACLK_SMMU_DECON0X>,
+ <&cmu_disp CLK_ACLK_XIU_DECON0X>,
+ <&cmu_disp CLK_PCLK_SMMU_DECON0X>,
+ <&cmu_disp CLK_SCLK_DECON_VCLK>,
+ <&cmu_disp CLK_SCLK_DECON_ECLK>;
+ clock-names = "aclk_decon", "aclk_smmu_decon0x", "aclk_xiu_decon0x",
+ "pclk_smmu_decon0x", "sclk_decon_vclk", "sclk_decon_eclk";
+ interrupt-names = "vsync", "lcd_sys";
+ interrupts = <0 202 0>, <0 203 0>;
+
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@0 {
+ reg = <0>;
+ decon_to_mic: endpoint {
+ remote-endpoint = <&mic_to_decon>;
+ };
+ };
+ };
+};
+
+Board specific DT entry:
+&decon {
+ i80-if-timings {
+ };
+};
