33193323Sed * All registers controlling various analog aspects of the SoC (such as PLLs or
34193323Sed * voltage regulators or USB VBUS detection) are gathered together under the
35193323Sed * anatop device (because of newbus hierarchical resource management), but other
36193323Sed * drivers such as CMM or USBPHY need access to these registers.  These
