The ePAPR standard [1] says:
The name of a node should be somewhat generic, reflecting the function of the
device and not its precise programming model. If appropriate, the name should
be one of the following choices:
[...]

+ compatible = "rockchip,rk3288-usb", "rockchip,rk3066-usb",
+ "snps,dwc2";
