[PATCH v2 8/8] ARM: bcm2835: Disable i2c2 in the Device Tree
From: Noralf TrÃnnes
Date: Tue Sep 27 2016 - 07:59:48 EST
i2c2 is connected to the HDMI connector and is controlled by the
firmware. Disable it to stay out of harms way.
>From the downstream commit:
i2c-bcm2708/BCM270X_DT: Add support for I2C2
The third I2C bus (I2C2) is normally reserved for HDMI use. Careless
use of this bus can break an attached display - use with caution.
It is recommended to disable accesses by VideoCore by setting
hdmi_ignore_edid=1 or hdmi_edid_file=1 in config.txt.
