From 347e40f0302c7e817e64256284b9e69a8b2711d2 Mon Sep 17 00:00:00 2001 From: Sudeep Holla Date: Wed, 21 Oct 2015 11:10:00 +0100 Subject: [PATCH] rtc: opal: enable support for the stardard "wakeup-source" property Though the opal rtc driver should and will continue to support the legacy "has-tpo" property to enable RTC as the wakeup source, we need to add support for the new standard property "wakeup-source" This patch adds support for "wakeup-source" property in addition to the existing "has-tpo" property.
