-* Device tree bindings for Aspeed Video Engine
-
-The Video Engine (VE) embedded in the Aspeed AST2400/2500/2600 SOCs can
-capture and compress video data from digital or analog sources.
-
-Required properties:
- - compatible:		"aspeed,ast2400-video-engine" or
-			"aspeed,ast2500-video-engine" or
-			"aspeed,ast2600-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
-
-Optional properties:
- - memory-region:
-	phandle to a memory region to allocate from, as defined in
-	Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt
-
-Example:
-
-video-engine@...00000 {
-    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>;
-    memory-region = <&video_engine_memory>;
