1 * Device tree bindings for Aspeed Video Engine
2
3 The Video Engine (VE) embedded in the Aspeed AST2400/2500/2600 SOCs can
4 capture and compress video data from digital or analog sources.
5
6 Required properties:
7 - compatible: "aspeed,ast2400-video-engine" or
8 "aspeed,ast2500-video-engine" or
9 "aspeed,ast2600-video-engine"
10 - reg: contains the offset and length of the VE memory region
11 - clocks: clock specifiers for the syscon clocks associated with
12 the VE (ordering must match the clock-names property)
13 - clock-names: "vclk" and "eclk"
14 - resets: reset specifier for the syscon reset associated with
15 the VE
16 - interrupts: the interrupt associated with the VE on this platform
17
18 Optional properties:
19 - memory-region:
20 phandle to a memory region to allocate from, as defined in
21 Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt
22
23 Example:
24
25 video-engine@1e700000 {
26 compatible = "aspeed,ast2500-video-engine";
27 reg = <0x1e700000 0x20000>;
28 clocks = <&syscon ASPEED_CLK_GATE_VCLK>, <&syscon ASPEED_CLK_GATE_ECLK>;
29 clock-names = "vclk", "eclk";
30 resets = <&syscon ASPEED_RESET_VIDEO>;
31 interrupts = <7>;
32 memory-region = <&video_engine_memory>;
33 };
