*	rtc: armada38x: fix concurrency access in armada38x_rtc_set_time	Gregory CLEMENT	2015-05-05	1	-12/+12
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	While setting the time, the RTC TIME register should not be accessed. However due to hardware constraints, setting the RTC time involves sleeping during 100ms. This sleep was done outside the critical section protected by the spinlock, so it was possible to read the RTC TIME register and get an incorrect value. This patch introduces a mutex for protecting the RTC TIME access, unlike the spinlock it is allowed to sleep in a critical section protected by a mutex. The RTC STATUS register can still be used from the interrupt handler but it has no effect on setting the time.

*	drivers/rtc/rtc-armada38x: add a new RTC driver for recent mvebu SoCs	Gregory CLEMENT	2015-02-13	1	-0/+320
	The new mvebu SoCs come with a new RTC driver. This patch adds the support for this new IP which is currently found in the Armada 38x SoCs. This RTC provides two alarms, but only the first one is used in the driver. The RTC also allows using periodic interrupts.
