rtc: add support for the S-35390A RTC chip

2008-03-05T00:35:09Z

This adds basic get/set time support for the Seiko Instruments S-35390A. This chip communicates using I2C and is used on the QNAP TS-109/TS-209 NAS devices.

rtc-cmos: display HPET emulation mode

2008-02-24T01:12:14Z

For the "cmos" RTC, have /proc/driver/rtc say whether HPET based IRQ emulation is in effect. Given the problems we've had with this particular hardware maldesign (and the fact that most BIOS code seems not to provide the IRQ routing needed to use the saner HPET modes), this should help troubleshooting.

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

2008-02-06T18:41:14Z

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

2008-02-06T18:41:14Z

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

2008-02-06T18:41:14Z

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.
