+Subject: [PATCH] arm64: dts: ls104x: use a pseudo-bus to constrain usb dma
+ size
+
+Wrap the usb controllers in an intermediate simple-bus and use it to
+constrain the dma address size of these usb controllers to the 40 bits
+that they generate toward the interconnect.
+This is required because the SoC uses 48 bits address sizes and this
+mismatch would lead to smmu context faults because the usb generates
+40-bit addresses while the smmu page tables are populated with 48-bit
+wide addresses.
