    1 * Mediatek Video Processor Unit
    2 
    3 Video Processor Unit is a HW video controller. It controls HW Codec including
    4 H.264/VP8/VP9 Decode, H.264/VP8 Encode and Image Processor (scale/rotate/color convert).
    5 
    6 Required 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 
   16 Optional 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 
   22 Example:
   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 	};
