The driver uses its own default, if not set in the devicetree. This information is hardware specific and should therefore be maintained in the devicetree rather than in the source. To be backward compatible, this field is not mandatory. If 'atu' resource is not specified in the devicetree, the driver=E2=80=99s default= value is used.
