1* Mediatek Video Processor Unit 2 3Video Processor Unit is a HW video controller. It controls HW Codec including 4H.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 base 11 "cfg_reg": Main configuration registers base 12 - interrupts: interrupt number to the cpu. 13 - clocks : clock name from clock manager 14 - clock-names: must be main. It is the main clock of VPU 15 16Optional properties: 17 - memory-region: phandle to a node describing memory (see 18 Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt) 19 to be used for VPU extended memory; if not present, VPU may be located 20 anywhere in the memory 21 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 };
