Subject: drm/tegra: sor: Hook up I2C-over-AUX to output
Git-commit: 6f684de537bcd813bcbdbc917c5b41b1fc5b7d8d
Patch-mainline: v5.5-rc1
References: bsc#1152472

This is necessary for the output abstraction to retrieve a list of valid
modes from the EDID of a connected panel/monitor. This will be useful in
conjunction with DisplayPort support that will be added in a subsequent
patch, so that the driver can read EDID via the AUX channel.
