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

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	};
