[PATCH v5 6/6] arm64: dts: allwinner: orange-pi-3: Enable HDMI output

From: megous
Date: Mon May 20 2019 - 19:52:53 EST


From: Ondrej Jirman <megous@xxxxxxxxxx>

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.
This is realized by the ddc-en-gpios property.
