Is this block in all arm SoCs from Mediatek?
If not, then I would prefer to use "mediatek,mtXXXX-jpgdec"
where XXXX stands for the oldest model which has this block.

In parallel to that the dts should have this compatible plus the one for 
mt2701, for example:
compatible = "mediatek,mt2701-uart", "mediatek,mt6577-uart"

Thanks,
