1* Device tree bindings for Aspeed Video Engine 2 3The Video Engine (VE) embedded in the Aspeed AST2400/2500/2600 SOCs can 4capture and compress video data from digital or analog sources. 5 6Required 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 18Optional 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 23Example: 24 25video-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}; 34
