0001 * Mediatek Video Processor Unit
0002
0003 Video Processor Unit is a HW video controller. It controls HW Codec including
0004 H.264/VP8/VP9 Decode, H.264/VP8 Encode and Image Processor (scale/rotate/color convert).
0005
0006 Required properties:
0007 - compatible: "mediatek,mt8173-vpu"
0008 - reg: Must contain an entry for each entry in reg-names.
0009 - reg-names: Must include the following entries:
0010 "tcm": tcm base
0011 "cfg_reg": Main configuration registers base
0012 - interrupts: interrupt number to the cpu.
0013 - clocks : clock name from clock manager
0014 - clock-names: must be main. It is the main clock of VPU
0015
0016 Optional properties:
0017 - memory-region: phandle to a node describing memory (see
0018 Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt)
0019 to be used for VPU extended memory; if not present, VPU may be located
0020 anywhere in the memory
0021
0022 Example:
0023 vpu: vpu@10020000 {
0024 compatible = "mediatek,mt8173-vpu";
0025 reg = <0 0x10020000 0 0x30000>,
0026 <0 0x10050000 0 0x100>;
0027 reg-names = "tcm", "cfg_reg";
0028 interrupts = <GIC_SPI 166 IRQ_TYPE_LEVEL_HIGH>;
0029 clocks = <&topckgen TOP_SCP_SEL>;
0030 clock-names = "main";
0031 };
