* Mediatek Video Processor Unit
|
|
Video Processor Unit is a HW video controller. It controls HW Codec including
|
H.264/VP8/VP9 Decode, H.264/VP8 Encode and Image Processor (scale/rotate/color convert).
|
|
Required properties:
|
- compatible: "mediatek,mt8173-vpu"
|
- reg: Must contain an entry for each entry in reg-names.
|
- reg-names: Must include the following entries:
|
"tcm": tcm base
|
"cfg_reg": Main configuration registers base
|
- interrupts: interrupt number to the cpu.
|
- clocks : clock name from clock manager
|
- clock-names: must be main. It is the main clock of VPU
|
|
Optional properties:
|
- memory-region: phandle to a node describing memory (see
|
Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt)
|
to be used for VPU extended memory; if not present, VPU may be located
|
anywhere in the memory
|
|
Example:
|
vpu: vpu@10020000 {
|
compatible = "mediatek,mt8173-vpu";
|
reg = <0 0x10020000 0 0x30000>,
|
<0 0x10050000 0 0x100>;
|
reg-names = "tcm", "cfg_reg";
|
interrupts = <GIC_SPI 166 IRQ_TYPE_LEVEL_HIGH>;
|
clocks = <&topckgen TOP_SCP_SEL>;
|
clock-names = "main";
|
};
