From a63b3bc7db32b63bfe5f48fa8582f931db81c86e Mon Sep 17 00:00:00 2001 From: "Dongsheng.wang@freescale.com" Date: Tue, 9 Apr 2013 10:22:32 +0800 Subject: powerpc/fsl: add MPIC timer wakeup support The driver provides a way to wake up the system by the MPIC timer. For example, echo 5 > /sys/devices/system/mpic/timer_wakeup echo standby > /sys/power/state After 5 seconds the MPIC timer will generate an interrupt to wake up the system.
