+Allwinner A80 Display Engine Clock Control Binding
+------------------------------------
+
+Required properties :
+- compatible: must contain one of the following compatibles:
+		- "allwinner,sun9i-a80-de-clocks"
+
+- reg: Must contain the registers base address and length
+- clocks: phandle to the clocks feeding the display engine subsystem.
+	  Three are needed:
+  - "mod": the display engine module clock
+  - "dram": the DRAM bus clock for the system
+  - "bus": the bus clock for the whole display engine subsystem
+- clock-names: Must contain the clock names described just above
+- resets: phandle to the reset control for the display engine subsystem.
+- #clock-cells : must contain 1
+- #reset-cells : must contain 1
+
+Example:
+de_clocks: clock@03000000 {
+	compatible = "allwinner,sun9i-a80-de-clks";
+	reg = <0x03000000 0x30>;
+	clocks = <&ccu CLK_DE>, <&ccu CLK_SDRAM>, <&ccu CLK_BUS_DE>;
+	clock-names = "mod", "dram", "bus";
+	resets = <&ccu RST_BUS_DE>;
+	#clock-cells = <1>;
+	#reset-cells = <1>;
+};
