rtc: at91sam9 RTC support (RTT and/or RTC)

2008-02-06T18:41:14+00:00

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.)

rtc: remove more dev->power.power_state usage

2008-02-06T18:41:14+00:00

Remove some more references to dev->power.power_state.  That field is overdue
for removal, but we can't do that while it's still referenced in the kernel.
The only reason to update it was to make the /sys/devices/.../power/state
files (now removed) work better.

rtc: add HPET RTC emulation to RTC_DRV_CMOS

2008-02-06T18:41:14+00:00

That patch adds the RTC emulation of the HPET timer to the new RTC_DRV_CMOS.
The old drivers/char/rtc.ko driver had that functionality and it's important
on new systems.

Blackfin RTC driver: read_alarm() checks the enabled field, not the pending field.

also, dont bother using memcpy since we can just do an assignment of the same structure.
