ARM: dts: sunxi: Fix dtc 'dma-ranges' warnings
'#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: arch/arm/boot/dts/sun5i.dtsi:189.4-52: Warning (dma_ranges_format): \ /soc/dram-controller@1c01000:dma-ranges: "dma-ranges" property has invalid length (12 bytes) (parent #address-cells == 1, child #address-cells == 2, #size-cells == 1) arch/arm/boot/dts/sun8i-r40.dtsi:742.4-52: Warning (dma_ranges_format): \ /soc/dram-controller@1c62000:dma-ranges: "dma-ranges" property has invalid length (12 bytes) (parent #address-cells == 1, child #address-cells == 2, #size-cells == 1) arch/arm/boot/dts/sunxi-h3-h5.dtsi:563.4-52: Warning (dma_ranges_format): \ /soc/dram-controller@1c62000:dma-ranges: "dma-ranges" property has invalid length (12 bytes) (parent #address-cells == 1, child #address-cells == 2, #size-cells == 1) Cc: Chen-Yu Tsai <wens@csie.org> Acked-by: Maxime Ripard <mripard@kernel.org> Signed-off-by: Rob Herring <robh@kernel.org>
