    ARM: dts: sunxi: Fix dtc 'dma-ranges' warnings · ac5fe2e6
    Rob Herring authored
    '#address-cells' and '#size-cells' are needed in the same node (for the
    child bus) as 'dma-ranges' in order to parse it. The kernel is more lax
    and will walk up the tree to get the properties from a parent node, but
    it's better to be explicit. dtc now does checks on 'dma-ranges' and is
    more strict:
