2016-05-21rtc: tps6586x: rename so module can be autoloadedNicolas Chauvet1-1/+1
This module is loaded by the related mfd driver which has the needed MODULE_DEVICE_TABLE(i2c,...). This patch fix the modalias when the rtc driver is built as a module, so the right name is used. Everything operates correctly when this module is builtin.

2016-05-20rtc: zynqmp: Update seconds time programming logicAnurag Kumar Vulisha1-6/+39
We program RTC time using SET_TIME_WRITE register and read the RTC current time using CURRENT_TIME register. When we set the time by writing into SET_TIME_WRITE Register and immediately try to read the rtc time from CURRENT_TIME register, the previous old value is returned instead of the new loaded time. This is because RTC takes nearly 1 sec to update the new loaded value into the CURRENT_TIME register. This behaviour is expected in our RTC IP. This patch updates the driver to read the current time from SET_TIME_WRITE register instead of CURRENT_TIME when rtc time is requested within an 1sec period after setting the RTC time. Doing so will ensure the correct time is given to the user. Since there is a delay of 1sec in updating the CURRENT_TIME we are loading set time +1sec while programming the SET_TIME_WRITE register, doing this will give correct time without any delay when read from CURRENT_TIME.

2016-05-20rtc: da9053: fix access ordering error during RTC interrupt at system power onSteve Twiss1-5/+8
This fix alters the ordering of the IRQ and device registrations in the RTC driver probe function. This change will apply to the RTC driver that supports both DA9052 and DA9053 PMICs. A problem could occur with the existing RTC driver if: A system is started from a cold boot using the PMIC RTC IRQ to initiate a power on operation. For instance, if an RTC alarm is used to start a platform from power off. The existing driver IRQ is requested before the device has been properly registered. i.e. ret = da9052_request_irq() comes before rtc->rtc = devm_rtc_device_register(); In this case, an interrupt exists before the device has been registered and the IRQ handler can be called immediately: this can happen be before the memory for rtc->rtc has been allocated. The IRQ handler da9052_rtc_irq() contains the function call: rtc_update_irq(rtc->rtc, 1, RTC_IRQF | RTC_AF); which in turn tries to access the unavailable rtc->rtc. The fix is to reorder the functions inside the RTC probe. The IRQ is requested after the RTC device resource has been registered so that da9052_request_irq() is the last thing to happen.

2016-05-20rtc: ds1307: ensure that any pending alarm is cleared before a new alarm is ↵Nicolas Boullis1-5/+8
enabled If a previously-set alarm was disabled and then triggered, it may still be pending when a new alarm is configured. Then, if the alarm is enabled before the pending alarm is cleared, then an interrupt is immediately raised. Unfortunately, when the alarm is cleared and enabled during the same I²C block write, the chip (at least the DS1339 I have) considers that the alarm is enabled before it is cleared, and raises an interrupt. This patch ensures that the pending alarm is cleared before the alarm is enabled.
