3] with the CLK_IGNORE_UNUSED flag for aclk200_disp1 CLK
on Exynos5420 based chromebook (peach-pit board)
Below procedures were followed to test S2R:
Procedure A:
1. make multi_v7_defconfig
2 enable MCPM for 5420
3. enable S3C RTC
5. echo +20 > /sys/class/rtc/rtc0/wakealarm && echo mem > /sys/power/state
Procedure B:
1. make exynos_defconfig
4. echo +20 > /sys/class/rtc/rtc0/wakealarm && echo mem > /sys/power/state
