+Subject: [PATCH] net: stmmac: notify the PM core of a wakeup event.
+
+In PM_SUSPEND_FREEZE and WOL(Wakeup On Lan) case, when the driver gets a
+wakeup event, either the driver or platform specific PM code should notify
+the pm core about it, so that the system can wakeup from low power.
+
+In cases where there is no involvement of platform specific PM, it
+becomes driver responsibility to notify the PM core to wakeup the
+system.
+
+Without this WOL with PM_SUSPEND_FREEZE does not work on STi based SOCs.
