-* 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 at 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>;
- memory-region = <&video_engine_memory>;
-};
