-* Mediatek JPEG Decoder

-Mediatek JPEG Decoder is the JPEG decode hardware present in Mediatek SoCs

-Required properties:
-- compatible : must be one of the following string:
-	"mediatek,mt8173-jpgdec"
-	"mediatek,mt7623-jpgdec", "mediatek,mt2701-jpgdec"
-	"mediatek,mt2701-jpgdec"
-- reg : physical base address of the jpeg decoder registers and length of
-  memory mapped region.
-- interrupts : interrupt number to the interrupt controller.
-- clocks: device clocks, see
-  Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
-- clock-names: must contain "jpgdec-smi" and "jpgdec".
-- power-domains: a phandle to the power domain, see
-  Documentation/devicetree/bindings/power/power_domain.txt for details.
-- mediatek,larb: must contain the local arbiters in the current Socs, see
-  Documentation/devicetree/bindings/memory-controllers/mediatek,smi-larb.yaml
