Pull arm-soc device tree description updates from Arnd Bergmann: "This branch contains two kinds of updates: Some platforms in the process of getting converted to device tree based booting, and the platform specific patches necessary for that are included here. Other platforms are already converted, so we just need to update the actual device tree source files and the binding documents to add support for new board and new drivers. In the future we will probably separate those into two branches, and in the long run, the plan is to move the device tree source files out of the kernel repository, but that has to wait until we have completed a much larger portion of the binding documents."

2012-07-17rtc-cmos: report wakeups from interrupt handlerPaul Fox
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.

2012-07-11drivers/rtc/rtc-twl.c: fix threaded IRQ to use IRQF_ONESHOTKevin Hilman
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.

2012-05-29drivers/rtc/rtc-m41t93.c: don't let get_time() reset M41T93_FLAG_OFNikolaus Voss
If the rtc reports the time might be invalid due to oscillator failure, M41T93_FLAG_OF flag must not be reset by get_time() as the read operation doesn't make the time valid. 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.

2012-05-20mfd: Convert wm831x to irq_domainMark Brown
The modern idiom is to use irq_domain to allocate interrupts. This is useful partly to allow further infrastructure to be based on the domains and partly because it makes it much easier to allocate virtual interrupts to devices as we don't need to allocate a contiguous range of interrupt numbers. Convert the wm831x driver over to this infrastructure, using a legacy IRQ mapping if an irq_base is specified in platform data and otherwise using a linear mapping, always registering the interrupts even if they won't ever be used. Only boards which need to use the GPIOs as interrupts should need to use an irq_base. This means that we can't use the MFD irq_base management since the unless we're using an explicit irq_base from platform data we can't rely on a linear mapping of interrupts. Instead we need to map things via the irq_domain - provide a conveniencem function wm831x_irq() to save a small amount of typing when doing so. Looking at this I couldn't clearly see anything the MFD core could do to make this nicer. Since we're not supporting device tree yet there's no meaningful advantage if we don't do this conversion in one, the fact that the interrupt resources are used for repeated IP blocks makes accessor functions for the irq_domain more trouble to do than they're worth.

The reset date of the ST Micro version of PL031 is 2000-01-01. The correct weekday for 2000-01-01 is saturday, but pl031 is initialized to sunday. This may lead to alarm malfunction, so configure the correct wday if RTC_DR indicates reset.

2012-04-12drivers/rtc/rtc-twl.c: use static register while reading timeKonstantin Shlyakhovoy
RTC stores time and date in several registers. Due to the fact that these registers can't be read instantaneously, there is a chance that reading from counting registers gives an error of one minute, one hour, one day, etc. To address this issue, the RTC has hardware support to copy the RTC counting registers to static shadowed registers. The current implementation does not use this feature, and in a stress test, we can reproduce this error at a rate of around two times per 300000 readings. Fix the implementation to ensure that the right snapshot of time is captured.
