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
