2016-09-21rtc: omap: Support ext_wakeup configurationMarcin Niestroj
Support configuration of ext_wakeup sources. This patch makes it possible to enable ext_wakeup and set it's polarity, depending on board configuration. AM335x's dedicated PMIC (tps65217) uses ext_wakeup to notify about power-button presses. Handling power-button presses enables to recover from RTC-only power states correctly.

2015-09-05ARM: dts: AM437x: Add the internal and external clock nodes for rtcKeerthy
rtc can either be supplied from internal 32k clock or external crystal generated 32k clock. Internal clock is SOC specific and the external clock is board dependent. Adding the corresponding nodes.

2015-08-12ARM: dts: AM4372: Add the am4372-rtc compatible stringKeerthy
am4372-rtc string was already part of dts, introduced to identify the rtc specific to am4372 family of SoCs. It was removed in one of the previous patches. Adding back the same with appropriate documentation. Signed-off-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2014-12-10rtc: omap: drop vendor-prefix from power-controller dt propertyJohan Hovold
Drop the vendor-prefix from the "ti,system-power-controller" device-tree property name. It has been agreed to make "system-power-controller" a standard property and to drop the vendor-prefix that is currently used by several drivers. Note that drivers that have used "<vendor>,system-power-controller" in a released kernel will need to support both versions.

2014-12-10rtc: omap: add support for pmic_power_enJohan Hovold
Add new property "ti,system-power-controller" to register the RTC as a power-off handler. Some RTC IP revisions can control an external PMIC via the pmic_power_en pin, which can be configured to transition to OFF on ALARM2 events and back to ON on subsequent ALARM (wakealarm) events. This is based on earlier work by Colin Foe-Parker and AnilKumar Ch.

2013-09-11drivers/rtc/rtc-omap.c: add rtc wakeup support to alarm eventsHebbar Gururaja
On some platforms (like AM33xx), a special register (RTC_IRQWAKEEN) is available to enable Alarm Wakeup feature. This register needs to be properly handled for the rtcwake to work properly. Platforms using such IP should set "ti,am3352-rtc" in rtc device dt compatibility node.
