| * rtc: wm831x: Feed the write counter into device_add_randomness()Mark Brown2012-07-191-1/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The tamper evident features of the RTC include the "write counter" which is a pseudo-random number regenerated whenever we set the RTC. Since this value is unpredictable it should provide some useful seeding to the random number generator. Only do this on boot since the goal is to seed the pool rather than add useful entropy.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | When suspending the system with an important RTC wake alarm active, it is possible that the RTC alarm will expire before the system has gone to sleep (e.g. short alarm timer, or an unusually long suspend routine). If this happens, the RTC alarm should trigger a wakeup event, possibly aborting system suspend. This condition can be detected in the form of an RTC alarm interrupt.

* | drivers/rtc/rtc-twl.c: fix threaded IRQ to use IRQF_ONESHOTKevin Hilman2012-07-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Requesting a threaded interrupt without a primary handler and without IRQF_ONESHOT is dangerous, and after commit 1c6c6952 ("genirq: Reject bogus threaded irq requests"), these requests are rejected. This causes ->probe() to fail, and the RTC driver not to be availble. To fix, add IRQF_ONESHOT to the IRQ flags. Tested on OMAP3730/OveroSTORM and OMAP4430/Panda board using rtcwake to wake from system suspend multiple times.

Without this patch, only the first get_time() reported an invalid time, the second get_time() reported a valid time althought the reported time is probably wrong due to oscillator failure. Instead of resetting in get_time(), with this patch M41T93_FLAG_OF is reset in set_time() when a valid time is to be written.
