From: Biwen Li <biwen.li@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
