   4 Subject: [PATCH] arm64: dts: ls104x: constrain sata dma address size
   5
   6 Limit the dma mask size for sata to 40 bits to match the actual address
   7 size generated towards the interconnect. Re-use the already existing
   8 auxiliary simple bus meant for usb but drop the usb reference from the
   9 node name.
