+* Device tree bindings for Aspeed Video Engine
+
+The Video Engine (VE) embedded in the Aspeed AST2400 and AST2500 SOCs can
+capture and compress video data from digital or analog sources.
+
+Required properties:
+ - compatible: "aspeed,ast2400-video-engine" or
+ "aspeed,ast2500-video-engine"
+ - reg: contains the offset and length of the VE memory region
+ - clocks: clock specifiers for the syscon clocks associated with
+ the VE (ordering must match the clock-names property)
+ - clock-names: "vclk" and "eclk"
+ - resets: reset specifier for the syscon reset associated with
+ the VE
+ - interrupts: the interrupt associated with the VE on this platform
+
+Example:
+
+video-engine@1e700000 {
+ compatible = "aspeed,ast2500-video-engine";
+ reg = <0x1e700000 0x20000>;
+ clocks = <&syscon ASPEED_CLK_GATE_VCLK>, <&syscon ASPEED_CLK_GATE_ECLK>;
+ clock-names = "vclk", "eclk";
+ resets = <&syscon ASPEED_RESET_VIDEO>;
+ interrupts = <7>;
+};
