Subject: [PATCH 1/1] arm64: dts: meson: g12b: odroid-n2: Add I2C RTC device node
Date: Tue,  2 Feb 2021 18:08:46 +0100	[thread overview]
Message-ID: <20210202170846.81685-1-alexander.stein@mailbox.org> (raw)

This is taken from the downstream kernel and works out of the box.
Similar to other boards, this RTC should be the primary one, rather than
the internal one.

A wakeup alarm by writing to /sys/class/rtc/rtc0/wakealarm works as well.
