33 * All registers controlling various analog aspects of the SoC (such as PLLs or
34 * voltage regulators or USB VBUS detection) are gathered together under the
35 * anatop device (because of newbus hierarchical resource management), but other
36 * drivers such as CMM or USBPHY need access to these registers.  These
37 * functions let them have at the hardware directly.  No effort is made by these
38 * functions to mediate concurrent access.
