[linux-sunxi] [PATCH v2 10/13] arm64: dts: allwinner: orange-pi-3: Enable HDMI output

[megous via linux-sunxi]

From: Ondrej Jirman <meg...@megous.com>

Orange Pi 3 has a DDC_CEC_EN signal connected to PH2, that enables the DDC
I2C bus voltage shifter. Before EDID can be read, we need to pull PH2 high.
