Subject: [PATCH 03/11] arm64: dts: meson: add support for the ODROID-N2+
HardKernel ODROID-N2+ uses an Amlogic S922X rev. C chip capable of higher
clock speeds than the original ODROID-N2.
The rev. C support a slighly higher VDDCPU_A & VDDCPU_B voltages and supports
the same OPPs as the Amlogic A311D SoC from the same G12B family.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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
downstream kernel.

Subject: [PATCH 11/11] arm64: dts: meson: add i2c2 node to ODROID N2/N2+
The J2 connectors pinout documents "I2C.SDA0/SCL0" on pin 3 and 5, which
are connected to GPIOX_17/18. This GPIO allow to mux I2C to the second
I2C instance. Enable i2c2 and use the appropriate pinmux.
