/*
* This driver uses two configurable hardware resources that live in the
* AT91SAM9 backup power domain (intended to be powered at all times)
* to implement the Real Time Clock interfaces
*
* - A "Real-time Timer" (RTT) counts up in seconds from a base time.
* We can't assign the counter value (CRTV) ... but we can reset it.
*
* - One of the "General Purpose Backup Registers" (GPBRs) holds the
* base time, normally an offset from the beginning of the POSIX
* epoch (1970-Jan-1 00:00:00 UTC). Some systems also include the
* local timezone's offset.
*
* The RTC's value is the RTT counter plus that offset. The RTC's alarm
* is likewise a base (ALMV) plus that offset.
*
* Not all RTTs will be used as RTCs; some systems have multiple RTTs to
* choose from, or a "real" RTC module. All systems have multiple GPBR
* registers available, likewise usable for more than "RTC" support.
