Now I have two RTC driver registered
$ dmesg | grep rtc
[ 4.737315] rtc-pcf8563 0-0051: registered as rtc0
[ 4.738763] rtc-pcf8563 0-0051: setting system clock to
2020-07-16T08:00:46 UTC (1594886446)
[ 4.790206] meson-vrtc ff8000a8.rtc: registered as rtc1
And there are two nodes
# ls /dev/rtc*
/dev/rtc /dev/rtc0 /dev/rtc1
So it seames an issue that /dev/rtc0 is not able to handle wakeup events.
How can we resolve this issue?
# time rtcwake -s 30 -m mem
rtcwake: /dev/rtc0 not enabled for wakeup events
real 0m0.002s
user 0m0.001s
sys 0m0.002s
