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
