This removes interrupts 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 interruptThe commit message need a little bit improvement. Something like: Since the interrupt pin for RTC DS1374 is not connected to the CPU on T4240RDB, remove the interrupt property from the device tree. This also fix the following warning for hwclock.util-linux: $ hwclock.util-linux hwclock.util-linux: select() to /dev/rtc0 to wait for clock tick timed out
