Subject: [PATCH v3 08/11] arm64: dts: allwinner: orange-pi-3: Enable HDMI output
Date:   Thu, 11 Apr 2019 12:19:48 +0200

From: Ondrej Jirman <megous@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.
