483 RTC driver for the Atmel AT91SAM9x internal RTT (Real Time Timer).
484 These timers are powered by the backup power supply (such as a
485 small coin cell battery), but do not need to be used as RTCs.

487 (On AT91SAM9rl chips you probably want to use the dedicated RTC
488 module and leave the RTT available for other uses.)

497 More than one RTT module is available. You can choose which
498 one will be used as an RTC. The default of zero is normally
499 OK to use, though some systems use that for non-RTC purposes.

509 The RTC driver needs to use one of the General Purpose Backup
510 Registers (GPBRs) as well as the RTT. You can choose which one
511 will be used. The default of zero is normally OK to use, but
512 on some systems other software needs to use that register.
