1* Mediatek Video Processor Unit2 3Video Processor Unit is a HW video controller. It controls HW Codec including4H.264/VP8/VP9 Decode, H.264/VP8 Encode and Image Processor (scale/rotate/color convert).5 6Required properties:7 - compatible: "mediatek,mt8173-vpu"8 - reg: Must contain an entry for each entry in reg-names.9 - reg-names: Must include the following entries:10 "tcm": tcm base11 "cfg_reg": Main configuration registers base12 - interrupts: interrupt number to the cpu.13 - clocks : clock name from clock manager14 - clock-names: must be main. It is the main clock of VPU15 16Optional properties:17 - memory-region: phandle to a node describing memory (see18 Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt)19 to be used for VPU extended memory; if not present, VPU may be located20 anywhere in the memory21 22Example:23 vpu: vpu@10020000 {24 compatible = "mediatek,mt8173-vpu";25 reg = <0 0x10020000 0 0x30000>,26 <0 0x10050000 0 0x100>;27 reg-names = "tcm", "cfg_reg";28 interrupts = <GIC_SPI 166 IRQ_TYPE_LEVEL_HIGH>;29 clocks = <&topckgen TOP_SCP_SEL>;30 clock-names = "main";31 };32
