* 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@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>;
|
|
};
