I went tried to this on exynos5800-peach-pi and found first that
exynos_defonfig is missing the MAX77802 kconfig options for the RTC
source clock:
CONFIG_REGULATOR_MAX77802=y
CONFIG_COMMON_CLK_MAX77802=y
With those, rtc0 then comes up, but isn't waking from suspend. However,
writing something to rtc0/wakealarm does result in /proc/interrupts
having an interrupt for the RTC, it's just not waking the system.
Anyone else tried this on 5800/peach-pi?
Kevin
