   4 Subject: [PATCH] arm64: dts: ls104x: make dma-coherent global to the SoC
   5
   6 These SoCs are really completely dma coherent in their entirety so add
   7 the dma-coherent property at the soc level in the device tree and drop
   8 the instances where it's specifically added to a few select devices.
