Subject: the dp helper would try to enable the i2c channel for rockchip-edp
Date: Wed, 19 Oct 2016 21:52:26 +0800 [thread overview]
Message-ID: <24daffe0-42a4-2a37-d685-7d9ecf9c3b11@rock-chips.com> (raw)
Hello,
Recently, I want to use a eDP panel in my RK3288 platform, but I got
the following message:
[ 8.935918] i2c i2c-6: of_i2c: modalias failure on /dp@ff970000/ports
[ 8.936018] rockchip-drm display-subsystem: bound ff970000.dp (ops
rockchip_dp_component_ops [analogix_dp_rockchip])
It try to enable the eDP aux channel and add a new I2C controller, but
it failed then the whole display subsystem is broken, the panel doesn't
power on either.
I hope somebody could figure out what is wrong with it.
