From: Biwen Li <biwen...@nxp.com>
This adds wakeup-source property to drop warning as follows:
- $ hwclock.util-linux
hwclock.util-linux: select() to /dev/rtc0
to wait for clock tick timed out
My case:
- RTC ds1339s INT pin isn't connected to cpus INT pin on T1024RDB,
then the RTC cannot inform cpu about alarm interrupt
How to fix it?
- add wakeup-source property and remove IRQ line
to set uie_unsupported flag
