+* Mediatek Video Processor Unit
+
+Video Processor Unit is a HW video controller. It controls HW Codec including
+H.264/VP8/VP9 Decode, H.264/VP8 Encode and Image Processor (scale/rotate/color convert).
+
+Required properties:
+ - compatible: "mediatek,mt8173-vpu"
+ - reg: Must contain an entry for each entry in reg-names.
+ - reg-names: Must include the following entries:
+ "tcm": tcm base
+ "cfg_reg": Main configuration registers base
+ - interrupts: interrupt number to the cpu.
+ - clocks : clock name from clock manager
+ - clock-names: must be main. It is the main clock of VPU
+
+Optional properties:
+ - memory-region: phandle to a node describing memory (see
+ Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt)
+ to be used for VPU extended memory; if not present, VPU may be located
+ anywhere in the memory
+
+Example:
+ vpu: vpu@...20000 {
+ compatible = "mediatek,mt8173-vpu";
+ reg = <0 0x10020000 0 0x30000>,
+ <0 0x10050000 0 0x100>;
+ reg-names = "tcm", "cfg_reg";
+ interrupts = <GIC_SPI 166 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&topckgen TOP_SCP_SEL>;
+ clock-names = "main";
+ };
