[PATCH 07/11] arm64: dts: ls1043a: make dma-coherent global to the SoC

Wed Aug 24 15:36:58 PDT 2022


ls1043a is really completely dma coherent in their entirety so add the
dma-coherent property at the soc level in the device tree and drop the
instances where it's specifically added to a few select devices.
