From: Biwen Li <biwen.li@nxp.com>
This adds uie_unsupported 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 ds1374's INT pin is connected to VCC on T4240RDB, then the RTC cannot inform cpu about the alarm interrupt
