From: Joonyoung Shim <jy0922.shim@samsung.com>

DECON(Display and Enhancement Controller) is new IP replacing FIMD in
Exynos5433. This patch adds Exynos5433 decon driver.

Signed-off-by: Joonyoung Shim <jy0922.shim@samsung.com>
Signed-off-by: Hyungwon Hwang <human.hwang@samsung.com>
---
Changes for v2:
- change file names and variable names of decon to represnt exynos5433 instead
of exynos to distinguish them from exynos7 decon

Changes for v3:
- fail fast when the proper image format is not set
- remove unnecessary checking code
- add and modify the function to make DPMS work well

Changes for v4:
- rebased to exynos-drm-next with the clean-up patchset by Gustavo Padovan.

Changes for v5:
- None

+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 {
+	};
+};
