+Subject: arm64: dts: add MUSB node to Allwinner A64 dtsi
+
+Allwinner A64 SoC has a MUSB controller like the one in A33, so add
+a node for it, just use the compatible of A33 MUSB.
+
+Host mode is tested to work properly on Pine64 and will be added into
+the device tree of Pine64 in next patch.
+
+Peripheral mode is also tested on Pine64, by changing dr_mode property
+of usb_otg node and use a non-standard USB Type-A to Type-A cable.
