Subject: [v2 1/2] dts: ppc: t4240rdb: remove interrupts property
Date: Wed, 20 May 2020 17:15:42 +0800 [thread overview]
Message-ID: <20200520091543.44692-1-biwen.li@oss.nxp.com> (raw)
From: Biwen Li <biwen.li@nxp.com>
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 interrupt
