Rebased on
1] Kukjin Kim's tree, master branch
http://git.kernel.org/cgit/linux/kernel/git/kgene/linux-samsung.git/log/
2] My 5420 PMU Series :
http://www.mail-archive.com/linux-samsung-soc@vger.kernel.org/msg35699.html

Tested on Exynos5800 based chromebook (peach-pi board) with help of
http://www.spinics.net/lists/linux-samsung-soc/msg33750.html (modified to support 5800)

Below procedures were followed to test S2R:
Procedure A:
	1. make multi_v7_defconfig 
	2  enable MCPM for 5420
	3. enable S3C RTC
	4. pass "no_console_suspend" in bootargs
	5. echo +20 > /sys/class/rtc/rtc0/wakealarm && echo mem > /sys/power/state
Procedure B:
	1. make exynos_defconfig 
	2  disable BL_SWITCHER
	3. pass "no_console_suspend" in bootargs
	4. echo +20 > /sys/class/rtc/rtc0/wakealarm && echo mem > /sys/power/state
