+Exynos MIPI DSI Master
+
+Required properties:
+  - compatible: value should be one of the following
+		"samsung,exynos3250-mipi-dsi" /* for Exynos3250/3472 SoCs */
+		"samsung,exynos4210-mipi-dsi" /* for Exynos4 SoCs */
+		"samsung,exynos5410-mipi-dsi" /* for Exynos5410/5420/5440 SoCs */
+		"samsung,exynos5422-mipi-dsi" /* for Exynos5422/5800 SoCs */
+		"samsung,exynos5433-mipi-dsi" /* for Exynos5433 SoCs */
+  - reg: physical base address and length of the registers set for the device
+  - interrupts: should contain DSI interrupt
+  - clocks: list of clock specifiers, must contain an entry for each required
+    entry in clock-names
+  - clock-names: should include "bus_clk"and "sclk_mipi" entries
+		 the use of "pll_clk" is deprecated
+  - phys: list of phy specifiers, must contain an entry for each required
+    entry in phy-names
+  - phy-names: should include "dsim" entry
+  - vddcore-supply: MIPI DSIM Core voltage supply (e.g. 1.1V)
+  - vddio-supply: MIPI DSIM I/O and PLL voltage supply (e.g. 1.8V)
+  - samsung,pll-clock-frequency: specifies frequency of the oscillator clock
+  - #address-cells, #size-cells: should be set respectively to <1> and <0>
+    according to DSI host bindings (see MIPI DSI bindings [1])
+
+Optional properties:
+  - power-domains: a phandle to DSIM power domain node
+
+Child nodes:
+  Should contain DSI peripheral nodes (see MIPI DSI bindings [1]).
+
+Video interfaces:
+  Device node can contain video interface port nodes according to [2].
+  The following are properties specific to those nodes:
+
+  port node inbound:
+    - reg: (required) must be 0.
+  port node outbound:
+    - reg: (required) must be 1.
+
+  endpoint node connected from mic node (reg = 0):
+    - remote-endpoint: specifies the endpoint in mic node. This node is required
+		       for Exynos5433 mipi dsi. So mic can access to panel node
+		       throughout this dsi node.
+  endpoint node connected to panel node (reg = 1):
+    - remote-endpoint: specifies the endpoint in panel node. This node is
+		       required in all kinds of exynos mipi dsi to represent
+		       the connection between mipi dsi and panel.
+    - samsung,burst-clock-frequency: specifies DSI frequency in high-speed burst
+      mode
+    - samsung,esc-clock-frequency: specifies DSI frequency in escape mode
