Re: [PATCH v5] rtc: omap: Support ext_wakeup configuration

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.

Hi,

This patch adds support for ext_wakeup using generic pinconf device-tree
bindings, with one added custom property.

Changes v4 -> v5 (suggested by Rob):
 * Don't use GPIO defines in ti,input-polarity, use optional ti,active-high
   boolean instead.
 * Use '-' instead of '_' in node name.

Changes v1 -> v4:
 * This is a total reimplementation, so it is not based on any of the previous
   patch versions. This approach has been suggested by Tony and Grygorii
   in [1].

Patch was developed on 4.7, rebased on 4.8-rc5, tested using chiliBoard.
