* Mediatek JPEG Codec

Mediatek JPEG Codec device driver is a v4l2 driver which can decode
JPEG-encoded video frames.

Required properties:
  - compatible : "mediatek,mt2701-jpgdec"
  - reg : Physical base address of the jpeg codec registers and length of
        memory mapped region.
  - interrupts : interrupt number to the cpu.
  - clocks : clock name from clock manager
  - clock-names: the clocks of the jpeg codec H/W
  - power-domains : a phandle to the power domain.
  - larb : must contain the larbes of current platform
  - iommus : Mediatek IOMMU H/W has designed the fixed associations with
        the multimedia H/W. and there is only one multimedia iommu domain.
        "iommus = <&iommu portid>" the "portid" is from
        dt-bindings\iommu\mt2701-iommu-port.h, it means that this portid will
        enable iommu. The portid default is disable iommu if "<&iommu portid>"
        don't be added.

Example:
	jpegdec: jpegdec@15004000 {
			compatible = "mediatek,mt2701-jpgdec";
			reg = <0 0x15004000 0 0x1000>;
			interrupts = <GIC_SPI 143 IRQ_TYPE_LEVEL_LOW>;
			clocks =  <&imgsys CLK_IMG_JPGDEC_SMI>,
				  <&imgsys CLK_IMG_JPGDEC>;
			clock-names = "venc-jpgdec-smi",
				      "venc-jpgdec";
			power-domains = <&scpsys MT2701_POWER_DOMAIN_ISP>;
			larb = <&larb2>;
			iommus = <&iommu M4U_PORT_JPGDEC_WDMA>,
				 <&iommu M4U_PORT_JPGDEC_BSDMA>;
	};
