Subject: [PATCH 1/9] arm64: dts: meson: add i2c3/rtc nodes and rtc aliases to
ODROID-N2 dtsi
Enable the onboard pcf8563 rtc hardware on ODROID N2/N2+ boards via the
common dtsi. Also add aliases to ensure vrtc does not claim /dev/rtc0.

Add simple GPIO fan node to support a fan on GPIO J8. Unfortunately the
pad used to control the fan does not support real PWM, hence the RPM
cannot be modulated.

Add the GPIO fan as a cooling device for the CPU thermal zone. Since we
have only full fan speed available with this, set the tripping point to
65°C which is the highest tripping point which Hardkernel used in their
