Subject: rtc: at91sam9 RTC support (RTT and/or RTC)
From: David Brownell <david-b@xxxxxxxxxxx>
AT91sam9 RTC support, primarily in the form of an RTT-as-RTC driver that was
extracted from 2.6.23-at91 patch and updated:
- Relies on now-merged platform updates, which associate the RTT
hardware address with each RTT and use the "at91_rtt" name.
- RTC framework related fixes and cleanups, notably:
* removed now-needless suspend/resume clock offset logic
* alarm read/write now respects the "enabled" flag
* suspend always disables update irqs
* shutdown (and startup) disables all irqs
- Misc cleanup:
* use dev_*() messaging
* add comments
* remove globals,
* ... etc
- Don't force use of RTT0 and GPBR0. Either resource may need
to be used for other purposes (like NO_HZ support).
- Update "AT91RM9200 RTC" Kconfig to allow it on SAM9RL chips
(it has both RTT and RTC).
Driver binding uses bus_find_device() to avoid needing any kind of "timer
library" code when there's more than one RTT module. (This timer can be used
as an RTC, to support NO_HZ operation, or potentially for other stuff. The
choice is a per-system policy.)
