Subject: [PATCH v2 10/13] arm64: dts: allwinner: orange-pi-3: Enable HDMI output
Date: Tue,  9 Apr 2019 02:24:49 +0200	[thread overview]
Message-ID: <20190409002452.14551-11-megous@megous.com> (raw)
In-Reply-To: <20190409002452.14551-1-megous@megous.com>

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.
