Subject: [PATCH 0/2] rtc: rtc-omap: add support for DT wakeup & alarm events

Current rtc-omap driver expects the rtc module wake-up capabilities to
be set up by board specific code. However, in case of DT, this is not
possible.

So, add a DT property "ti,wakeup_capable" to indicate that the module
is wake-up capable.

Also, on some platforms (like AM33xx), a special register
(RTC_IRQWAKEEN) is available to enable Wakeup feature for Alarm Events.

Since new platforms/Boards are now added through DT only, this feature
is supported via DT property only. Platforms using such IP should add
the property "ti,has_irq_wake_enb" in rtc DT node.

Kernel Base for the series is

linux-omap-dt.git
	> linux-omap-git/for_3.11/dts
