+* 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 = < 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 "< portid>"
+don't be added.

+Example:
