-* 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@10020000 {
-		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";
-	};
